Hi
Unfortunately mechanical skills are not my forte. I am mounting a buffer atachment to my used motor.This comes with a shaft adapter which is almost completely round with a slice cut out. Am I supposed to place the set screws so that they contact and tighten thru the cutout to the motor shaft, or tighten them on the adapter itself? Its a dumb question? but having said that I am of the belief that there are no stupid questions, maybe stupid answers.

In a perfect setup you would tighten the screw onto a flat cut on the shaft. That way when the set screw marks the shaft you could still slide on a pulley because the flat is below the shaft. (make sense). If you mess up the shaft it it's very hard to add or remove a puller. Of course most motor shafts don't have a flat on them.
So I would say, tighten it in the slot, thats a keyway slot BTW, that way you don't mess up the shafts surface. If you ever want to put a pulley on the motor you can file the keyway flat again. Make sense?
Thanks it makes perfect sense. Thank You

Hi Keith You say you adapter is almost round with a slice cut out, right? That would be for a key, and if your motor shaft also has a key way than you could use a key to keep your adapter from turning, the set screws would keep it from sliding off. However there is not much torque normally when buffing or polishing so just using the set screws should be ok, but if you ever have a problem with the adapter slipping get a key in there that will stop it.
Did you mount your motor in a box already ?? Make sure you have enough ventilation in there. I have a small motor buffer, I have it just sit on the bench, have look if you will it's in one of my photo albums, I find that there is not that much dust buildup and never bothered to enclose it.

If you are talking about a Beall buffing system, the adapter has a taper to it, and is used for a Morse Taper (MT) device, like a lathe. So the mandrel mounts on the adapter, which goes into the Lathe.
Otherwise, mount the buffer to the shaft of the motor, without using the adapter.
Hi Bruce
Bruce you are muddling things up a bit imo
The Beall system comes with 3 buffs with mandrels, 2 polishing bars and a wax bar, and a quick change shaft adapter, it fits on a straight 1/2" or 5/8" shaft.
A #2 Morse Taper with a straight end is available separately, the quick change shaft adapter fits on the straight end of the MT mandrel and the mandrel can be used in a lathe, the MT mandrel is drilled and tapped for a draw bar to use in a lathe
Here's a link for a quick look for those interested

NEWS!
The beale system I have is the model intended for a separate motor other than lathe mounting. It comes with 3 buffers that screw indivually into an adapter to fit a motor separate from the lathe. I tried to purchase the lathe mounting system but was unable to get a unit with a #2 morse taper only a #1. Strange or what!
