That's one reason I went with a gear motor at 105 rpm's. Another plus is the fact that now I don't have as much stress and wear on the mill bearings that I would from a belted application and less danger from moving parts like belts and pulleys.

Okay only issue I have found is that I cannot find a 12" that can go onto the mill shaft that is 3/8". The motor shaft is 1/2" so no issues there. Anyone know of a way around this?

Buy a piece of 1/2 in bar stock and drill a 3/8 hole down the center. Drill and tap a hole in the side for a set screw.

Should I make it wider or the same width of the pulley. Worried about keeping in balance and stability.

I would make it the same width but it really doesn't matter. I would also use a lathe or drill press to insure that you are drilling exactly down the center of the bar stock or you will get a wobble in the pulley.

Mine is the exact spec you list. 120 volt single phase, 1750 rpm, 1/3 hp, and 60 hz.

I run a 1.5 inch pulley on the motor shaft and a 9 incher on the grain mill. Works wonderfully. Starts up with grain in the hopper, and never seems to be burdened.
