Title: GA28 in Silverton Oregon
Post by: rhenryinoregon on October 31, 2020, 10:32:42 PM
After about six months of studying plans, reading these blogs, meeting builders, cleaning and organizing my shop, and buying tools and basic supplies, Iím starting my GA28! Today I bought supplies to build the saw horses, building jig and epoxy cabinet. Iíd told a lot of people I was going to start this project in October and by God I did!  Ladies and Gentlemen, the saw horse. Hey, you gottta start somewhere.

Awesome Bro! Huge Milestone. I'm still in the planning stages, can't wait to see your build come along.

I built mine from left over scrap material from an unrelated project.  One of my biggest regret is not building stackable horses with a removable/replaceable top since I like to cut through the tops.  They take up a lot of room in the shop when they are not being used

I haven't cut a horse in half yet, but I definitely like the design of the ones in the book; stackable, durable, easy. Good luck with your build, I remember the day I laminated the first part of my (1st) stem, and thinking if I was getting in over my head and whatnot. Then you blink and it's 2 years later and you look up at a big giant boat. Willamette valley is becoming a GA hot spot...

Thanks all. I know there are many different saw horse designs out there and I looked at a few. This design works and is stout. On to epoxy bench now. I think Iím going to use a greenhouse seed bed heat mat on the back wall as a heat source. Simple and Iíve already got one. Iíll be ordering my first batch of plywood and epoxy later this week.

I called Barry today to order my first 15 gallons. Should be here next week. I spent my lunch calling plywood dealers to source my first batch of wood and am very glad I called around. Prices vary A LOT! Will probably drive to PDX on Saturday to pick up a load of Okoume. Happy to be started!

Iíve not checked prices, but use crosscut hardwoods for everything.   Descent supply and a couple different options.

If you're in Oregon/Washington, you can often save $$$ in shipping by ordering from Edensaw ... call them and ask if there are any local businesses close to you that have a shipment coming up. The local businesses will often agree to have your stack of plywood delivered with theirs for little cost or for free.  I did it ... it works.

Post by: rhenryinoregon on November 06, 2020, 10:00:40 AM
Thanks, now that's a helpful tip (plenty here). I will call them today. I had planned to call Edensaw today. One question and I know it's been discussed lots on these pages, but I'm reading up on the differences between Okoume and Hydrotek. I'm wondering if Hydrotek on for the bottom construction would be an advantage because of it's rot restistance and strength? I know fully encapsulating all the plywood in epoxy should mitigate concerns, but anything that reduces risk of rot can't be a bad thing. It's a little extra weight, but as noted, this boat will still be plenty light. Thoughts?

I used hydrotek on the bottom of my build, and okoume on the roof... I liked working with hydrotek better. It's heavier and stiffer but as you pointed out more rot resistant, and the extra weight on the bottom will probably be (marginally) advantageous keeping the vertical c/g lower. I also found the quality of hydrotek/aquatek to be better, the okoume I got had some voids but from what I have heard that was an exception, not the rule. I have yet to find a void in hydrotek or aquatek. That said, if I had a do-over I would probably use aquatek for the whole thing except the roof and/or up high, it's great for any structural application where you aren't going to bright finish it (and costs about half as much as the same dimension panels of joubert okoume). Something else to note, I also used some cdx and other fir ply from home depot for some under deck stuff (secondary stringers, non-critical sole supports, etc) and for the amount of extra work to even fill voids and glass the panels I would not go that route again I don't think. I would however not hesitate to use MDO, from what I have used of it it has all been high quality, very few voids and also perfectly fair surfaces to start with. It's just very heavy.

That's very helpful as well. I've now called 15 suppliers for price quotes - around the US as well as Oregon and Washington. Mr. Plywood in PDX is cheapest on hydrotek, and Crosscut is best on Okoume. I have a couple of quotes coming on line. Your logic is where I'm ending up so I'll probably do the same - hydrotek down low and okoume up high. Thanks!

I built the hull from hydrotech, and everything else from okoume.  like said above.  Hydrotech is heavier, I used on the hull.  That's not to say I didn't use bits for small stuff that was laying around, but I bought nothing except okoume for the above deck stuff.  My supplier when asked gave me the various weights of the sheets by comparison.  1/4" okoume was 7 pounds lighter per sheet than hydrotech.  I didn't weigh it, I'm not convinced it could be that much lighter.  It is a featherweight, super light stuff!
  It should be noted that aquateck is for use above the waterline and not intended for below the waterline.

Iím continuing on but with hiccups. My wife left her job because repeated Covid exposures were causing us to be constantly quarantined, so weíre a one-income family for the moment. I have some supplies stockpiled but didnít make it up for the wood purchase yet - had to let the dust settle and do some financial prioritization. Once we decided food and heat were less important than building the boat, I was able to start up again. Some questions on the platform: itís not LVL, instead I glued up my own wood I-beam from 2x6ís and OSB webbing. Iíll show a cross section. Itís very stout, straight and will be sufficient. Casters are on and itís supported mid-section. Iím about to square it up. Heavy bolts hold the legs to frame and the casters are set.  Iíll go take some photos. I noticed another builder had used TJI joists for the frame and it worked well, so thatís my logic. I still need to do a little cleaning!

Today I got the epoxy cabinet built today. Made completely of scrapped or repurposed wood and hinges and stuff. Insulated it with foam padding - sort of minimal but it might be okay. The heat source is a seed bed warmer. Iíll see how it works.

Good to see you getting going.  That batch of epoxy will be the first of many!   I think Iím up to 30 gallons, with about 2 gallons to go before Iím out.  Hope the mixer works well for you.  I tend to over pour the gardener by a gram or two on every batch

Iíll be cutting the bow stem and sheer shelves this weekend. Question. I have access to two very nice and sentimental pieces of wood that would be great for the stem. One is a 4x6 rough cut ponderosa beam from the original cabin my grandfather built in 1960, since torn down. Knot-free, solid, and straight. The other is a gorgeous tight/straight grain old growth Douglas fir beam Iíve used in various places for 30 years - kids swing for a while, then as a porch post. itís more weathered then the ponderosa but is solid. Would the Ponderosa be okay for the stem? Iíll plane it down to ensure itís solid. Iíd love to say Iíve got a piece of Grandpaís cabin in my boat. I know the Doug fir is probably better though.

My first effort at scarfing yesterday. I wonít be able to glue today because I donít have my fiberglass additives yet, but I should be able to work on some other parts. The plywood is all cut to width, the stem is done and the shop organization continues as I go.

Well, my first bonehead move of the build, the first of a few Iím sure. I was finishing up scarfing and realized the two half-sheets of plywood that needed scarfing were not 3/8Ē! They weíre 1/2Ē. Wasted sheet. Hopefully there will be opportunity to use the 1/2Ē as scrap of or for other parts.
Title: Re: GA28 in Silverton Oregon
Post by: Todd j on November 29, 2020, 10:39:22 PM
Those scarfs look perfect enough.  Great work!   One thin I discovered was it was easier to make all the scarfs just right when I put an extra sheet on the bottom of the stack to sacrifice.  Makes it easier for me to get the ďfirstĒ sheet I need,  to a better scarf.  Your doing a good job

There will be PLENTY of need for that 3/8" wood later :) ...

I usually just use a narrow, full-width, piece of scrap under the bottom sheet when milling the scarfs ... say 48" wide by 14" to 16" wide.  You can re-use this piece on subsequent scarfing work - just line up the previously-cut scarf with the scarf lines on the edges of the to-be scarfed wood on top.  It'll still help guide that power hand planer.

Hey Brian. I need to buy the stringers and Iím not sure what length to get. If Iím going to do the extended euro or rounded stern with outback motor mount, do I add a couple feet to the 28í length? I think that takes me to two 25í LVLs, is that correct?

Yes.  That's the short answer.  The stringers just extend further aft with the same 14-deg deadrise bevel.  If your extended (for swim platform or whatever) hull is a hull extension like I recommend, then just add the extra length ... take what's specified for 28-foot boat as the base - if building a 30-footer or putting a 24" extended bottom (swim platform) onto a 28-footer ... it's the same as a 30-foot boat regardless.  Just add 2 feet to the length specified for a 28-footer.

Try to get uncoated LVL, e.g. I believe Boise Cascade makes them for your neck of the woods.  If you can only get coated, just lightly plane off the surface, taking the coating with it.  If you can't get the full length required, scarf extra LVL length onto the aft end of the ones you CAN get.  Instructions for scarfing LVL beams to make longer beams is shown in the Kodiak Addendum.

Hope that helps!

You can get them plenty long without scarfing. Just need to go to an actual lumber yard not the big box stores. When I do kits I just tell them how long (Lineal Feet) I want each type and size. Here in bend I get them the next day

Huh. I was figuring on adding some height at the deck level later but maybe I should go with taller studs...  shoot. Later I guess.

Post by: Todd j on December 02, 2020, 08:29:51 PM
Add sheer deck height with the horses and move the stringers with them.  Add to the stringers tops after the flip.  Thats what I  did.  You can slope the deck in the cockpit this way.  Glass the primary stringers all around then add, also provides a rot stop.

"Add sheer deck height with the horses and move the stringers with them". Feeling stupid - I don't know what you mean here.


The horses support the stringers while you put the sides on (when the bottom assembly is laying upside down on top of them) and define where they lay in relation to the shelves and ultimately define how tall your side panels will be. So if you have taller lvl or want your sheer taller you need to account for it in the height of the support structure (horses) and make them taller or shorter so that the shelves and the stringers have the correct spatial relationship. Then once you have built that the way you intend and have flipped the boat you can pay more attention to how much of a cockpit sole raise and slope you want (which hopefully was considered when changing the sheer and/or stringer height), you have more options to play with instead of a dead flat stringer surface. I built with all standard kodiak dimensions and just raised my cockpit deck about 5" and the sheer is still mid-thigh high for me, which I think is plenty for what I intend to use the boat for (I am not especially tall though). I think the kodiak sheer is 4 or 5" higher than the standard though, but would have to double check that.
Title: Re: GA28 in Silverton Oregon
Post by: Brian.Dixon on December 03, 2020, 06:33:16 AM

The 'horses' are called "temporary frames" in the plans, FYI.

If you change things up to adjust the height of the sides, as explained above, don't forget that you also need to adjust the length of the stem to match, and loft your transom to match as well.

Post by: Todd j on December 03, 2020, 06:44:31 AM
Sorry for confusing terminology.  I was thinking you wanted to increase the freeboard dimension over the plans.  I raise the tops of the framing 4 1/2Ē as Brian described.  You can then Add that number to height dimension of the stringers.  Then everything inside the boat above the decks is design height.    If you donít raise the sheer decks obviously you lose the design height after the boat is decked.  It does have some trickledown  as Brian describes.  If I had it to do again I would not keep the same transom overall width.  I would use the angles as designed and made the transom slightly wider to accommodate the larger height.  More reserve displacement, though minimal you get a bigger boat.  HTH

Post by: rhenryinoregon on December 03, 2020, 08:15:01 AM
Got it, thanks all. Iím still learning the lingo. Iíll have to think about that. Wouldnít raising the sheer, if you want to keep the side angle the same also mean the lofting for the sheers would have to be modified to make them wider because they would be moved up and out? It would only be an inch or two but still different. I guess I could graph that out and adjust the lofting dimensions, probably not too hard. But Iíd need to do that now.

I've never known anyone to keep the side flare the same when adjusting side height - going taller by a couple of inches makes an invisible difference on the boat - can't see the difference with your eyes (and the ocean doesn't care, so?).  Making the boat wider on a Standard Great Alaskan risks blowing the 8'6" highway width limitation and require a Wide Load permit and sign.  On the Kodiak model of the Great Alaskan, making the sheer a little wider is NOT a problem ... It's already wide enough to require the Wide Load permit ... the next limit is 10' wide ... quite a bit wider.  If you managed to blow the 10' limit, then you'll need a pilot car and driver, signage, possible lights/markers etc.  It's not advisable to build a 10-ft wide Great Alaskan ... for other reasons as well.

The boat's got plenty of interior freeboard if you just want to raise the cockpit deck (commonly done) ... especially if you add the cockpit coaming as shown on the Prince Rupert.

Actually thatís what I plan on doing on the coaming. I have a sailrite sewing machine and plan to do a nice detachable pad on either side, plus davit, electric downriggers and radar, which I already have.

I just had a nice visit from FedEx with my fiberglass tape and various powders so tomorrow should be my first real day of glueing hopefully. Got my LVLs coming on Tuesday and theyíre delivering to my door which is super helpful as well.

Looking good, Randy!  Note that when the side panels are put on, that they'll naturally fair that outside curve and bumps/hollows just result in a place for epoxy to fill and make the joint stronger.  No need to over-work that outside curve.  And the inside curve will be hidden under sheer deck plywood or have coaming on it ... again, a little wiggle here and there is no big deal either.  Just an FYI that may help save time and effort.

That'll work.  When you get to lofting the chine flats, note that from the bow aft, they get wider up to amidships ... but taper a little bit narrower as they continue onward to the transom.  Don't be alarmed ... this is by design and provides the widest chine flat at the point of greatest lift -- In the image below, the pointy blue line is the waterline when on plane at 22 knots ... the red line is the line of highest pressure (lift), also when on plane at 22 knots (for a 26-foot Great Alaskan):

Yup ... for a boat this size, it's an iterative slow process to get everything optimized ... And it performs exactly as predicted :D.  Based on how badly so many commercially-made boats perform, I'm quite certain that the Great Alaskan got FAR more due diligence and FAR more optimization than most boats out there.  I had a friend with a SeaSwirl ... we all had to go f'w'd, 2 people in the cuddy, to get the thing on plane.  It would just stick it's nose up in the air and jam along, not going on plane until everyone charged forward to get some weight in the bow ... amazing how some outfits will go all the way into manufacturing and production on a boat that just 'looks good on paper'... You're right!

Brian - when it comes time for hatches and covers, seems like it would be as good as anything to fabricate them from 1/2Ē Aquatech with 30 oz of glass cured in a vacuum. Wouldnít that be as stout and long lasting as commercially made products if well fitted? I suppose ďwell fittedĒ is the key.

I would think so.  I'm not a huge fan of plastic - it's convenient more than anything and there's a million selections.  And if you want to keep the space under a deck dry, those screw-in or quick-release plastic deck plates aren't going to work for you.  Hatches tend to be fine regardless (the several hundred dollar options for on top of the cuddy roof etc).  For vertical surfaces, or areas where you don't care if a little water makes it in (like over the bilge, just inside the transom), then the plastic stuff works fine and saves you time (Bomar, SeaDog etc).  You can probably do a better job with wood and glass if you want to take the time.

In your video you talk about putting a layer of 10oz glass on the one joint that did not turn out as well as the rest. I could be wrong but I am pretty sure Brian calls for an extra layer of glass backing on all scarf joints, both sides. Maybe that's just my rule I tend to over build a tad :)

Your moving right along!  I only remember taping the scarfs on the shelves for what it is worth.  I will say that i broke the scarfs on the spray rails on both sides of the boat when applying them to the hull.  I used the 2 layer method with 8 foot chunks of cvg.  Lessons learned there was long pieces from to start with from the bow, aft.  Shorter pieces where the boat was less turn-ie were fine.  The break caused only aggravation as I would have put the front pieces on a day sooner.  There was a pretty good discussion in my build thread on the placement of the rails when I did my build and Brian mentioned changing some numbers in future plans packages.  I know this  isn't much help to you yet, but thought it worth mentioning as there are several projects that are new right now.  Cheers and Merry Christmas all

The strip of 10-oz tape over the scarf joints is not required ... but if those long unwieldy plywood assemblies are lifted and moved around before the scarf joints have really cured well, especially if moving the wood understaffed, then it doesn't hurt to add the glass reinforcement.  Personally, I'd avoid it, let it cure well, then handle the wood carefully as you go ... who wants to do more fairing?

Yes, you want to avoid having spray rail, or rub rail, scarfs in the forward third of the boat where the sharpest bends are.  If you must, just make sure you use a nice long scarf, 8:1 minimum, and cure well before installing.  Not just a good idea during the build process, note that if you ding up your spray rails badly enough to expose wood, and then don't get them sealed up well again, then moisture can swell the wood to the point that the can break and pop off the boat - when the wood swells, it wants to straighten back out ... with amazing force ... no fun.  Saw it happen just once.  It's not a bad idea to at least have glass over the scarf joints ... then they'll never break.  Plywood is FAR LESS likely to have this issue, BTW.  Swelling and breaking is primarily an issue with solid wood rails.  Your boat will out-last you if you just make sure that it's always encapsulated with epoxy ... fix the dings when they occur ... you can still go fishing while the new epoxy is still a little green.  Water won't hurt it ...

Title: Re: GA28 in Silverton Oregon
Post by: rhenryinoregon on December 23, 2020, 10:58:51 AM
Thanks for all the feedback and tips. The main reason for the glass strip is I was trying to figure out if that skarf could be salvaged. I ran my electric planer down the joint and took off 1/32" of wood and resin to open it up. I gouged out the unevenly filled gap and refilled it with thickened epoxy, then laid the 3" strip down it. It inset into the 1/32" recess well and will be smooth and easily faired. Probably overkill but I'll feel better knowing it's there. After reading the comments, I think I'll use plywood for the spray rails as well.

Question: After trimming the bottom to shape, I've got a good, long well-skarfed 3/4" strip that will work very well for the aft sheer shelf. I know I'll need to add 3/8" to that as well, but I'm seeing no downside and probably an upside for using it there.  Any issues?

Last question for the moment: I'm going to cut the 3/8" fore-hull sections today so I can stitch the boat bottom together on the jig, maybe tomorrow (after work of course). I guess I need to decide on my transom design sooner or later. Probably either option will be to extend the planing hull by 24" for a swim deck arrangement. Should I skarf an additional 24" to the aft of the hull bottom now? I'm thinking I should.. The transom will stay at 28' so those measurements should all be good.

It's because the shelf lofting is wider than a 48" wide sheet of plywood and unless you want to do some funky scarfing, it's easiest to make templates for these and then either scarf or laminate shelves to fit.  In the case  of bottom panels and chine flats, the first one you make IS a template (for the other side).

You need the proverbial 'moaning chair' in the shop, eh?  Mistakes are part of the game...

So, on the f'w'd chine, the inside line that fits the outer edge of the bottom panels is supposed to be cut before installation.  The f'w'd OUTER line, however is not.  This leaves material that can be clamped to an athwartships 'straight edge' ... so you can get your chine flat installation just right, pulled in at the bow if necessary.  Once locked in and glassed, then the f'w'd chine flat outer line is cut to produce a nice taper inward to the bow where the flats end in a point.

If you already cut the outer line, I guess you can try fitting it.  The thin f'w'd tips can break if you have to pull them inward with clamps and with the chine flat being narrower in the f'w'd sections, it may be hard to clamp them to the aforementioned 'straight edge' above.  It's free to try, however, so why not?  If it appears too difficult, then you can replace the forward end at that time ... there's more than one way to skin a cat...

Guess I missed not cutting the outer line on the chines until after installing on the bottom. Every kit I have ever done both Tolman & the GA has always been finish cut on both inside and outside lines. So far I am on my 2nd GA and built one Tolman all 3 chines were cut prior to installing on the hull. Zip ties with 1x6 clamped on top going across both chines with peanut butter works for me. sorry don't have a picture of the chine tips.
P.S. Just found a picture from my widebody build that shows the chine attached with bailing wire. I use zip ties now

I went one step further.    I bought 2 remote control air filters and put them in opposite corners.  Itís amazing how quickly they fill up with dust.   I reuse the filters a couple of times.   When you empty them it reminds you what you are breathing

Of course you are right. I donít like my current mask a lot so Iíll look into the suggestions and get one ordered. I do have an air cleaner in my main shop and will move it out here once I really get going, especially sanding fiberglass.

Post by: Grady300 on December 31, 2020, 12:30:14 PM
Maybe I am making a huge mistake but I rarely wear a mask while applying epoxy or sanding unless I am in a more confined area. I use a 42" fan that seems blow all the fumes away. I also have a high volume fan in the bow of the hull blowing aft at all times. If I smell anything I put my mask on. They are spendey but if you get one of the electric DA sanders that hook to a vacuum and use the sanding disk that have the holes in the pad to suck up the dust works great. I suspect the better the unit the better is sucks up the dust. I have a festool DA sander and it picks up 98% of all dust, with the fans ya don't need anything IMHO. 
here is a link to the main system. You also need the sander which is another $425+- you will get your money out of it works really well

Yes but... You have an amazing big beautiful shop with lots of space and good equipment that helps control the dust.  I think youíve taken plenty of precautions. One thing about putting the videos out - I get lots of advice and some of its even good! I have used my dust mask and respirator but Iíll need to be more consistent as I go. Eye protection too. My brother took a shard of metal in the eye a few years ago and the result has been incredibly expensive and painful.

When I built my Tolman Widebody it was at my shop at my home at the time. That shop was only 28x36 so much smaller. I still utilized fans but I used a mask a whole lot more for both epoxy work and especially sanding. I didn't have the Festool sander at that time

Hey Brian: I have a few days away with family so Iím scrolling through the feeds trying to find transom design information. I want to do the swim step or Euro design. I like DJeffreyís rounded boat transom a lot. I see his initial sketch on page 1 of his build thread. I have my LVLs long enough to have this configuration on a 28í GA with 26Ē platform length. However my bottom pieces are not this long. So I assume I need to scarf the additional length to the end of my bottom pieces, as well as the chine pieces. Correct? Do you have any additional suggestions on the main and secondary transom - 1Ē thick for forward and 2Ē for motor mounting transom. Any other advice as I pursue this angle?

Yeah ... you'll have to ask around for further details since I haven't worked through that stuff yet, but several have extended the hull with a swim platform as you know.  The 1" thick f'w'd (original) transom with a 2" thick aft transom on a swim platform is perfect.  Extending the stringers, bottom panels and chine flats, with a swim platform on top is the best way to do it and works very well.  The curved transom is strongest, but must be laminated up on a mold to build it.  These 'little adjustments' to the original plan eat up a LOT of time to figure out and do, so consider carefully and keep it simple.   Do a lot of research on those that have gone before and already done it.  Someday, I'll add the instructions to the plans, perhaps as an addendum, but life is far too busy for that now!

Iíve been making it too hard... I think all I want to do is build 29-30í GA with a short transom/motor mount and a bulkhead at the 27-28í mark (with door) to maintain the freeboard. Then I donít really have to do any structural modifications. Spending all day on this probably saved me a lot of time later.

For air filtration in my 14'x20' garage with a 20' widebody shoved in I bought a box fan, some 20x25 furnace filters (they are a little big though cheaper than the right size), and duct tape them on. The fan is hung horizontally in the rafters with some bailing wire. It's wired to come on with the shop lights. I change the filters every couple days. Super half ass compared to some setups though it has the same results for a lot less time and money.  It definitely helps the air in the shop, not perfect though better than nothing. I've also been using the vacuum attachment for my circular and table saw and ordered but haven't tried one for my power plane. My sanders have built in dust collection.

I actually have a homage unit my son made in shop class that uses two bathroom fans and a couple of filters. Itís pretty good but I keep that in my smaller enclosed shop. Iíve considered something like what your describing for the boat cave. I have ordered a coupler for my DeWalt hand tools so I can put them directly to my shop vac. Having that for the planer would have saved a BIG mess. I actually lost my boat manual under that one day!
Title: Re: GA28 in Silverton Oregon
Post by: ghelland on January 03, 2021, 06:44:57 PM
I went to Home depot and got this cyclone separator (on the bucket) to save on filters.  It works pretty good.
With your changes to the stern it looks like we are building the same boat.

Thanks for the tips on dust control. I did just receive a new dust mask and I think Iíll relocate my present air cleaner to the building area.

Also, after a great deal of consideration, I think Iím going with the stern design that Brian detailed in the plans. Itís so clean looking and the extra storage will be appreciated. I guess now Iíll consider fish boxes and additional storage back there. Now I can build my stern!

A latest acquisition: Lewmar Prosport 550 anchor windlass. I got it used and tore it down, put in all new bearings, new grease and seals, and sealed it back up. Sanded and repainted as well. Iím not sure this is adequate for a 28í GA and it doesnít have free fall so I might be looking to trade up at some point if anyone is interested.  Or maybe Iíll put it on my Thunderjet.

Hey Brian or anyone else. Happy Friday. Iím starting on my transom now and revising the plans. I have decided to go with the standard design and for a single main motor. Should I consider a small offset to the main motor? And why would I do that? Is it to counteract torque or to address the kicker weight? What are the downsides of an offset? Maybe thereís already a thread...
Title: Re: GA28 in Silverton Oregon
Post by: Brian.Dixon on January 08, 2021, 04:17:52 PM

The only real downside to having an off-center motor, especially if you raise the motor a tad since the deadrise goes up, is that you can get some cavitation when turning hard (usually when going slow) towards the opposite side... if that makes sense.  No real reason that I can think of to mount the motor off center.

I don't have the plans in front of me but Brian does call out a height for the jig to be off the floor. You might also add a few inches if you are raising your sides up past the sheer shelves up front. If you go much lower on your jig you may not have enough height above the floor where the sheer shelfs meet at the bow while its upside down. Leave yourself a way to get under the hull while on the jig you will do it a lot. You will have a few new bruises on you head and your shins!!!

Good advice Todd. I had both sizes left over from another build I never finished. The 50" was way more versatile, if you are buying a smaller size for a specific use then that makes sense just don't get a lot of extra IMHO.

So when you say ďsome,Ē roughly what are you talking? Just for the exterior hull and maybe parts of the cabin? Iím not terribly concerned about the interior hull bottom, or should I be?   Noahís had the best prices by far on fabric but they are way behind on shipments.
Title: Re: GA28 in Silverton Oregon
Post by: Todd j on January 25, 2021, 06:18:11 PM
I usually roughly using head scratch math think about what I have next to glass.  For instance you will use at least 4 sheets for the deck.  Preglass the top and bottom of each sheet.  Thatís 64 feet right there.  I did 6 on bottom and 10 oz on top.  Preglass pilothouse bulkhead.  Fore and aft. Thatís another 50 feet.  Pilothouse side panels 4 sheets-ish.  You get the idea.  60 linear feet of each in 6 and 10 oz is a good starting point.  All the left over chunks are already glassed and ready to use elsewhere.  For me itís cheap enough I donít care if bits wind up in the trash.  My time is too valuable.  I like to glass one side of a sheet at the end of a work session.  End of next session do the other side.   Then you always have a sheet or two ready to rip.  Same goes for all the extra stringers.  The list goes on.  I would never buy the 30Ē cloth if I could do over.  You can even use up the scrap pieces of cloth on under deck parts where the overlap doesnít need fairing. 
  I think Brian should add it to the BOM itís super useful
  My .02
Also.  I use Foberglass Supply.  Sometimes I take delivery the next day and Iím west of eugene

You will find the 50" cloth to give you the best yield with less seams which means less sanding.

On the Epoxy from E-bond, I found the 1285/1285 better for fillets and smaller tasks, for glassing large panels 1285/1289 is far easier, thinner and wets out glass faster and no rushing.

That's what extra epoxy is for ... when you finish glassing something, or saturating end grain on something, and you find you have extra epoxy ... keep applying it to available end grain ... and if nothing else, paint it onto something - extra epoxy doesn't hurt.  Don't waste it!

Randy, you are correct I noticed the fairbady seam being glassed the whole way, no big deal. If you haven't been to Harbour Freight yet to get there cheap small hand held grinder with 36 grit flapper sand disk, go get one best $50 you will ever spend. It will make quick work of ANY grinding job you have. Extra glas on the chine perfect but like you say not necessary. I take every chance I get to overlap a seam if I can, I don't just want bulletproof I want crash proof ya never know what's 6" under the surface. See ya Saturday if ya make it

Post by: Rbob on January 28, 2021, 09:00:54 AM
Randy,

Funny I did the same thing, glassing all the way to the end of the fairbody, I am sure others have or will.  Chuck gave good advice on removing the fillet but to remove just the glass its quite easy.  A strait edge to make a cut in the glass and a heat gun to soften the epoxy enough to get the glass to pull off.  Once you can get a scraper or putty knife under the edge of the glass you can grab a hold of it and pull while using a heat gun along the edge you are pulling.

You guys are working too hard!  The bottom panel assembly rests on the (upside down) transom when it's installed.  I would just trim the bottom edge of the transom to fit the shape of the fillet/glass that went all the way to the end.  Stay away from hot epoxy!

Extra glass is just extra weight, and not much at that.  This isn't a canoe!  Keep on truckin'... Git'r done, Billy Bob!

I think you got your glass from Nohas, they have good pricing but they are slow. I couldn't even get the on the phone after 3 attempts. I started going to Fiberglass supply in WA. normally once I place the order I get it the next day or the day after. I'm sure you would be the same shipping time.

I am rigging chain hoists now and will hopefully flip it this week so I can glass the backside this weekend. I added a bracket to the platform and hung the fiberglass roll in it.

Hopefully when you say "glass the backside this weekend", you mean taping the bottom (towards water) chine flat-to-bottom panel seams ... not glassing the whole thing, right?  You won't do that until the transom, side panels, and bottom panel assembly (including 2nd layer in the bow area) are all assembled and you're glassing the whole exterior of the boat.

Looking great!  Well done!

I thought about my wording after I posted but was too lazy to fix it. Just the fair body up to the 3/8Ē , and the chines too, right? Iíll double check before I get in there. Thanks for keeping me honest. Not like Iíve got this nailed.

The chine flats are very solid after being glassed on the inside, even though there's no glass tape on the outside seam.  You'll assemble everything as mentioned, add the 2nd layer of 3/8" ply on the bow, then (see constr. manual) you may want to fair things in a bit at the bow before doing any glassing .... then finally, fill all gaps and screw holes and glass the chine flat-to-bottom panel seam.  After the side panels are on and fair, then you'll glass the side panel-to-chine flat seam, then sheath the whole boat in glass.  I like to scrape edges and fair them before each subsequent layer of glass ... makes the final fairing easier.

Nothing like a good ice storm and power outage to screw up a three day weekend of boat building!

We got 7" or 8" here in Star, Idaho ... refreshing since this part of Idaho almost never gets more than a spotty 1/2" snowfall...

About all Iíve managed to do between cutting up trees and clearing limbs is flip my boat bottom. My son was very helpful and the chain hoists made it easy. I prepped the chines and bottom for taping but alas Iím exhausted and will now sit by the wood stove for the evening.

Thanks. Been slow lately. I think Iíve decided to do an 8í temp extension off my shop. Itís getting a bit tight. Really looking forward to getting it up on the frame and adding the shelves and sides.

Chines and fair body are taped and drying. Looks good. If I donít work tomorrow I may hoist it up and start building the frame. Looking forward to that.

Video update! Power outages really out a crimp in things. I spent yesterday getting the platform ready for the boat frame and laying down the sheer shelves.

This is the first video update.  https://youtu.be/vd_P8U9W7HM (https://youtu.be/vd_P8U9W7HM)

And here is the second.  https://youtu.be/Lwj1lMpTx_0 (https://youtu.be/Lwj1lMpTx_0)

Power is back on! Got the shelves down yesterday, temporarily placed with stem in approximate location. Nothing glued yet as I want to make sure this stage is done to the letter.

This is the first time Iíve really felt the size of this beast!

This is really fun and Iím totally stoked. But boy itís gonna be a tight fit as the build moves on. Once the LVLs are in place Iím really gonna do some remodeling to squeeze out every inch of space.

Tight shops sometimes mean rolling the boat/jig out of the shop, doing stuff, then rolling it back in ... or building a temporary shop extension so you can leave the boat out longer.  It's worth it in the end!

Yup, Iím thinking about 8-12í longer would be good. Iíve always figured that as an option. I can live with the limited space side to side but I need space to pre-glass and assemble stuff.
