Stimson Roof Shed

[Rbob]

For those of you that want a cheap shelter, you may not get plans anymore but you can do it yourself.  You can use the midievel math (video below) and a string or use paper and a compass, or even Sketchup will work.  There are lots of videos on assembly of the stimson roof or gothic arch.

Once you have the arc drawn you can take measurements along a strait line drawn the end points, similar to making a roof template.

On Edit, Or use a long batten like this video:

If you use sketch up I would make the arc intersect with the diagonal line, I tried using a circle to intersect the points but it does not work very good.  pic of the arc:
