I have a huge sheet of 1/32 ply but I want to use balsa for the gussets so I can use CA. I think the last time I built a stick plane like this was in 1960, a 62 inch cub. This is good practice for when I get to the Howard Pete but it has a lot more formers to glue to. I did build a couple of Proctor RB planes teaching a kid how to do it about 10 years ago? The building went OK but using silk span was a thrill. Now there is a lot of top formers to epoxy in, more hurry up and wait!
