Found some aluminum at the local scrap dealer - good price! At least what I could drop from what was in the wallet.
So my question is how to extend longerons (of an airframe to be covered with cloth) by putting wood on the end? My thinking:
* Aluminum front for crash resistance
* Wood on the back for lightness/cost/whatever
* All materials "Available In Town" to save freight
* And cheaply, so I can "build one to throw away."
The aluminum extrusion has an "C" channel like area that the wood would go into. It would be epoxied in. Questions:
?=Should bolts be used, or would they tear out faster than the strength they add?
?=How much overlap (wood inside the aluminum)?
?=Where to join them? Closer to front? Back?
Thanking you all in advance!
