I have been known to use the RBs for A lot of things but CharlieP just showed me something new. Holding spars??? Why haven't I come up with that one. Today I was out of ammonia so I just shot down the 1/32 ply with water then bent with RBs to shape. I let it set up then tomorrow I will glue and epoxy the sheeting down. This is just pre shaping to make life easier. Thanks for that tip Charlie!!!!!!!
