Steel doesn't require structural epoxy. I would much rather weld than glue. You don't have to worry about getting the mixture ratio correct, getting the components thoroughly mixed, more tolerance for gaps between parts, and you don't have to wait a week for the part to cure before you go on to the next operation.
I also have this dream of having a low cost twin using a pair of VW engines (although the fact that the corvair engines can be run both ways may make them more desirable). I don't think hanging an engine on an existing KR wing spar is going to be practical. Because of the twisting moment generated by the engine hanging out in front of the wing, I expect the mounts are going to have to connect to both spars or the spars are going to need to be connected. Also, the spar loads will change significantly with the engine weight on the wing not the fuselage. I don't want to think about trying to do the design analysis with material that has directional strength properties (i.e. spruce). If you are going to use a steel (or aluminum) wing, you might as well convert the fuselage also. -- wesley scott [email protected] ----- Original Message ----- From: "Colin & Bev Rainey" <[email protected]> To: "KRnet" <[email protected]> Sent: Wednesday, June 23, 2004 2:20 PM Subject: KR> steel frame > Wesley > Why would you want a steel frame? Pound for pound spruce is lighter at the same strength unless you use one of the exotic metals, then you might as well pick a different plane. > > Colin & Bev Rainey > KR2(td) N96TA > Sanford, FL > [email protected] > http://kr-builder.org/Colin/index.html > _______________________________________ > to UNsubscribe from KRnet, send a message to [email protected] > please see other KRnet info at http://www.krnet.org/info.html > > >
