Found a few more errors in the plans and building instructions tonight. After all of the bottom formers were installed the instructions direct you to glue a 1/8" ply former (Z-1) to the front of the second F-1 former. OK... there is a nice schedule on Plan #3 that shows all of the Formers except - yes you guessed it Z-1 no biggie just annoying. The other mistake is that Z-1 is supposed to be 1/8" thick, the Z-1 ply is actually 3/32" not 1/8". Again no big deal just not acurate. Hopefully anyone building this model in the future will have this info.... Note: the side strigers are left long as I like to trim them all flush by sanding when they are all glued in place. Ply Z-1 is visable in the photo.
