On mounting the motor to the plate you used countersunk screw, would a pan head screw not have been better. Would the countersunk not tend to want to split the wood after a while due to how it grips?
Looking neat as usual
With the mounting bolts, I used the ones that came with the motor because they are mated by the manufacturer
to the internal threadson the motor. Since the 53mm diameter,plywood circle mount seemed to be aircraft
quality and very sturdy, I did not mind that the phillips headbolt had a tapered shoulder. Also, I used the supplied
screws to mount the plate, with motor attached, to the"cowl" which was reinforced with two layers of plywood
behind the fiberglass exterior opening.
I always drill pilot holes first and then screw in the bolt or screw. Then I remove the bolt or screw and apply a drop
of thin CA into each hole and when it dries, your threaded hole had been strengthened substantially. Give it a try.
