Decided to go "Van's" route, and built the all-moving stabilizer first. AND the extra forty two 3 inch corner blocks that the twelve 1/8 birch ply ribs will require. The latter are now cut out to symmetrical form and only require sanding edges and holes drilled to lighten. Have not planned out the structure of the anti-servo tab yet. Final cutting of ribs from their blanks was accomplished with the part in my lap, bridged across one knee with one hand stabilizing and the other holding an 18 tooth per inch small wave hack saw blade. You may now burst out laughing hysterically and roll on floor if necessary. Wooden planes are most definitely "hand built".
