I have a set of the WAF that TET made and they are nice,as Mark said I had to ream the holes out,but other then that they have not chipped at all.I don't know how with a wood spar you could torque them and think the would stay torque.I'm snugging them up and using AN lock nuts with a cotter key.I'm not a expert and have not flown it yet,but I feel pretty good about it staying together.And I'm not gluing mine on in any way,just in case I have to remove them for any reason down the road.
