If one were drill through the 5/8 square spruce and epoxy in that hole a steel tube, would that make the piece weaker? I plan to do a destructive test to find out, but your thoughts would be appreciated. If epoxy is stronger than the wood, and the steel is stronger than the wood, would it not

I have thought that if I were to do this again on a plane that was not already skinned, that I would make a space for the tube to pass through the stringers, but would put a doubler at the place where I drilled the hole. In that case, I would think that you could use any material you wish for a con

I don't see how it could be much stronger being skinned on the outside and inside ++ I would like to see the structural guys reaction on this one - I would like to do exactly that in my 115% rendition of a KR. In fact, I would like to take the inner skin from the firewall to the

RE: making something stronger may be causing a structural problem somewhere else That is very true. I think that skinning behind the rear spar will add much weight where you don't want it. I would like to see someone use a triangle of skin glued over the stringer joints, instead of gussets an

RE: I might use a pulley on the back side of the forward spar and one mounted off the aft spar or I might just use the nylaflow tube again If you use the pulleys, you will never have to be concerned about the wear. I may have a couple extra around here somewhere that you can have. "There is a ti
