For the good advice they passed along.

On my jointer I found out that both set screws were loose, so I
remounted both pulleys (shaft fit of each was nice and tight) from
scratch using a plum bob and then squirting locktite in the holes before
tightening the allen screws down. I tightened down so hard that I broke
the shell on each.  

Next time around I'll retap and maybe go for two screws with nylon
locking inserts.

For my bandsaw, I think I'll retap to start with and maybe even use an
old fashioned sqare headed set screw.  These might cause balance
problems, but they sure tighten down more firmly than the allen screws.

Cheers!

Kit

I know I'm a little late on this one, and there were many good
suggestions already. But there is one other tactic that I can suggest.
Use the two setscrews as others mentioned, and set the one over the key
first. Then using a drill of the correct tap size, drill down thru the
second setscrew hole (with the screw removed first) and spot the motor
shaft with the drill point. Just drill deep enough to get a dimple the
full diameter of the drill. Then loctite the screw in place in the
dimple. Your pulley will never drift using this method. This is commonly
done of mechanical drives.
