Let the wing construction begin. The wings will be foam rib construction. About 20 years ago I made this jig to build a Urley 33% Laser. The ends have sagged over the years so before beginning I added 2'X4'x5/8" particle board to the top. This really increased the weight but it is flat now. The jigs are made to bolt together to allow the wing tube to be cut at the same time in both panels. The wing tube centerline is layed out from tip to tip. Parting stock is use to retain the foam blanks in place per plan spacing. The strips are held in place with braids.
I normally use 1/2" thick blue foam with 5" rib spacing, the plans show slightly less than 4" spacing so I plan to reduce the 1/2" foam to 3/8" to keep similar weight construction.
