If you're an EAA member, you can get free access to scanned copies of all the oldSport Aviation magazines. N3513 was featured in an article in July 1969, writtenby the original builder. In the article, there is a bit about the struts- apparently 1/4" ply sandwiched between two layers of 3/8" Douglas Fir. Also,the strut fittings were made of .065 4130 steel, with steel bushings throughthe wood at each bolt location.Gotta agree whole-heartedly with Clif on the wingtip thing. The plans-built tipsare elegant. I have not seen a variation that looks anywhere nearly as good.In looking through old magazine and newsletter articles I recall seeing referencesto builders installing spill plates - back in the sixties, I think (andseem to think that even BHP tried them), but the trend died - thankfully.
