I did pretty much the same as Jeff except I used blind nut which has little serrations that seat it into the wood and then I also epoxied a small slab of plywood over it before closing the spar to capture the nut permanently. Then the 1/4" by 2" eye-bolt goes into the flight bag. Joe Horton
----- Original Message ----- From: "Jeff Scott via KRnet" <krnet at list.krnet.org> I have a nut buried in the last outboard segment of spar on either wing and an eye bolt that threads in from the bottom of the wing through the spar and into the nut. ?Since the nut was only floxed into place, I don't remove the eye bolts, but it wouldn't be difficult to make the nut captive and the eyebolts removable. -Jeff Scott Los Alamos, NM > > > I'm searching or some tie down attach points. ?What have you KR builders > found to work well? ?What was used and where/how installed? > Thanks, > Gary >
