Steve I definitely wanna chat about rail shaping. That's my only problem with the parallel profile method, shaping end grain is a timely process so any ideas on making that aspect better is a plus. Roy seems to obviously have it down but his boards take hundreds of hours ! Can you post some pics of your rails on the 10-7 u made ? Thanks dude !
That's an interesting variant--incorporating the torsion frame into the edge veneers. I can't picture what you're trying to accomplish with the concave, so I'm very interested to see what your plan is.
Actually it's my standard 4 layer parallel profile method, not a variant.
