Nice plane. I have one built up and doped, ready for color. I have had mine built up since who knows when, as I bought the plans immediately after they were released to the public, as the designer is local to me. However, I am a very slooooooooow builder sometimes, and this is one of them. Ok. I looked at the plan, and it is dated 2005, so sometime in 2005 I will assume I started mine....
And add to Ken's comment on the spruce. I too added a spruce stringer to mine as well to stiffen it ip a good bit. It is something I actually do on 99% of my all sheet 1/2a planes for strength. If I have to laminate 2 pieces for the correct chord, I put the stringer in the middle. If I use just a single sheet, I add it to the front.
