grrrrrrr...OK i feel like an idiot already. I finally got to tart building my plane today and the first dang step I feel like I have messed up already. please help clear this up if you can.

step 1. cut 9 1/16" off the end of each of two pieces 1/4" x 1/2" x 36" main spar stock. Glue these pieces to the remainder as center section spar doublers. cut two piece of 1/4" square stock 28 5/8" long. cut two other pieces 9 1/16" long. glue the 9 1/16" to the 28 5/8" pieces in the same was shown in Picture 1 above of the 1/4" x 1/2" spar.

OK. now the 9 1/16 = 9 inches and 1/16 of an inch correct?
