We're not talking about going down to Home Depot and getting a sheet of 1" CDX. All the layers would have the grain running spanwise, but every other one is flipped so any grain angularity is cancelled out. I know that laminated wood is stronger, I've done it myself and seen the results, but I have no idea how to calculate it to put a number to the strength. I know the design, built to plans, is more than strong enough, but I'd really like to put the dihedral break in the middle of the fuselage instead of out in the airstream. -- Steve N205FT [email protected] He who seeks will find, and he who knocks will be let in.
