Yes, it is nice having Ms Jones help out, sure speeds up the process and adds an element of quality control that I sometimes do not have. Unfortunately, she is off to Ireland to take her 90 year old mother back home to visit the extended family, so I am on my own for a few weeks. Today,I made my cabin rooftop beams out of white oak. Uses my CNC to make a template for a pattern cutting bit, and used my router to cut out the beams. Amazing what a sharp router bit will do. I also cut scarfs on my 3 1/2 sheets of 1/4 ply for my cabin roof and coated them with epoxy. We have a stretch of good weather, so I can use my barn for coating sheets of plywood as my shop is full with the boat. My plan is to make a sandwich roof with two layers of 1/4 inch ply with insulation and room for wiring between them. Plan to build right on the top of the boat, and "scarf in place" the pieces of plywood. Would love any thoughts on this idea, also suggestions on what to use for insulation between the layers.
