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?

(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.

It tests a bunch of different types of construction for built up wing spars. You can find it at. http://naca.larc.nasa.gov/reports/1920/naca-report-35/ Chris Sacramento, CA --- Jim Markle wrote: --> Pietenpol-List message posted by: Jim Markle 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.
