Well, I can hear a tiny bit of hesitation in my Tech Counselor's voice when we
talk about my decision to use marine grade 1/2" ply built up into an I beam for
the spar on my Air Camper.
Sure would be nice to show him the calculations the Brits are using or anything
else that (clearly) shows the numbers. I can review the shear/moment/etc numbers
on ply versus spruce/doug fir but if anyone knows of a good paper that's
been done, that would sure help me present my case.
Doc Mosher? Alan James?
Thanks,
Jim in Plano

Thanks for the good words about the video tape, Oscar. (cute dog, by the
way) Info on the video and
ordering info is available at this web
site: http://users.aol.com/bpabpabpa/cuyvideo.html
Fred-- if you have a VCR in Australia that can play a non-PAL format my
tape will work fine for you. Otherwise
you'll have to take the tape to a place and have it dubbed from the US into
the PAL format so it will play
correctly on your VCR. Simon McCormack (Tasmania, Australia) and I found
this out while exchanging video
tapes over that past several years)

Fred: The US format is NTSC if you do not allready know that.... And Mike's
tape is well worth having converted....

You could try reading the NACA paper entitled "The Strength of One-Piece Solid
Built Up and Laminated Wood Airplane Wing Beams" it's from 1920. It tests a bunch
of different types of construction for built up wing spars. You can find
it at.
