that's an idea for thought. I'm getting ready to start machining parts Don Reid suggests that the waf's almost as they are, are probably sufficient my view is that how the spar sets are attached to the stock fuselage it shouldn't bve too hard to come up with something at least that structurally soundhartwi...@juno.com wrote: Don, It might be better to install "butterfly" blocks between the spar caps at the attach point with the steel fuselage (similar to the landing gear attach blocks seen on Lynn Hyder's KR2-- http://home.hiwaay.net/~langford/lhyder/)-- one 1/2 " bolt through the block and an attach fitting welded at each side of the fuselage for the main spar and smaller bolts for the rear spar. The block would also even out the stresses at the fuselage juncture. Check out Falconar or Jodel plans--they have wood fuselages, but I believe they only use bolts to attach the wing spar to the fuselage. An alternative would be to box in the spar with the steel of the fuselage sides and require only small bolts through the "butterfly" block to hold it in place. Dick H
