Ha! I live in a condo and have no shop tools, but I figure out a way to do stuff with a DeWalt drill, a couple of Dremels and the little Dremel drill press, sanding blocks, razor saws, and... um... that's about it! Already I have figured out a work-around for making the ply discs and a clean, level cut of the balsa dount using the hand drill, a bolt and 2 nuts and a razor saw. The order of construction will have to be modified a bit, but it will absolutely work.

Your photo depicts what I had in mind, so I'm on the right track. Seems you have about 2.5 deg right thrust?

Hmm... looks as if your new design has a canalizer. Craftsmanship looks excellent. I hope to see the final product in person next season!
