Hey All Contributors. You Guys rock! I've glued up the shafts on my first set, 3/4" CVG doug fir (1x4 trim easiest to get a hold of). So shaft will be made of 3 laminated pieces. Without giving it much thought till now I was going to make the blades parallel to the glue joints, loading perpendicular to leaves of laminate, just like in a glulam beam. I did notice in a few pics early in this thread that glue joint was parallel to load. Opinions one way or another? Or don't overthink it... build... test... repeat.
