I dont think they grow stickaspruce any where near the east coast. You might try contacting Fred Trebb and Sons Inc. Spruce Specialists http://home.att.net/~jr-vanslyke/fredtebb/index.htm I think they are in Oragon. Marine plywood is plane old 3ply plywood except they don't have voyds in the inside plys like regular construction grades. Aircraft plywood is good stuff. You might need to join the EAA and get there wood working hand book it would be a lot easyer than trying to learn all you need to know here. I hope this helps WEBERHARD@aol.com wrote: > FlyBaby > > Hi, > I,m a new flybaby builder. I have been diligently studying the plans and am > at the point of ordering materials.
