My wing is a three piece with solid 3/4"spars.Now for some questions:1. Has anyone actually weighed a three piece wing and a one piece wing that werebuilt similarly and truly found the weight difference is 15-16 lbs. or are weall going along with a fifty year old assumption that came from a casual remarkby someone at a fly-in?2. Why would BHP's method of scarfing be good in 1930 but not in 2001?3. Why do my e-mails to Mike Cuy keep getting returned?4. Why does it take me three tries to get one good cowl?Larry________________________________________________________________________________

I have weighed all the parts and bolts needed for the three piece wing and came up with about 4 pounds. I posted this information a while back, so it could be in the archieve. The scarf method used by BHP would still work fine in that exact application and spar thickness. Other scarf methods may be better, however. You won't need a scarf at all with a three piece wing. Not sure where Mike is. What part of the cowl are you building? Doug Bryant________________________________________________________________________________
