Still waters.

Bmatthews.would it matter which way I biased the support bearing ? Closer to the engine,or indifferent ? Plucking my Guitar string didn't teach me much about a shaft I don't have yet.
Further,I know a hollow shaft,versus a solid one is better for most variables involved in these dynamics..
My intent was to press the forward end of the hollow shaft into an interference fit hole in the prop support ,and forget about it..We intend to turn a 14 x 6 prop so the proper fit will be sufficient....
At the engine end ,I want an adapter that will screw on the crankshaft,and be locked by a nut screwed AWAY from the cylinder,toward the prop,to lock the adapter from coming loose with the starting force.
I envisioned the shaft sliding into the adapter,with set screws on opposite sides,to lock it down.
Is a universal joint necessary? I'd prefer not to use one.
