At .009" I would think about some epoxy and a spiral flute reamer another way would be a smear of epoxy and clamp a bit of Aluminium in the slot with the edge aligned so that a straight flute reamer could be used.
I ended up using some aluminum shim stock and have the pulley mounted tight and straighter with less torque on the clamp bolt. I now have .090" of wobble, I'm going to leave it there and watch to make sure the aluminum shims don't loosen up. Maybe I'll rebore it later if this doesn't hold.
Thanks for all the ideas.
That it is...The best thing about aluminum shim stock is it's always close at hand

Breakage is a concern, but if it bent one way will it bend back? probably not worth the risk.
I tried 2 belts, the motor has a 2 groove pulley but they were not a matched pair and the length difference was to much so I ran the shorter one until it gave up then ran the longer one and now it's given up. I bought a double belt to fix it but I must have measured wrong and it was to long so I tossed it aside and ran it the way it was. I'm in the process of changing the motor pulley to a larger size, should increase the compressor speed about 20%, it's only turning about 325 RPM now, the new pulley will get it up to about 400 RPM. I modified the mounting hardware so with the bigger pulley and more adjustment room the double belt should fit.
With 5HP compressors running single belts I figured that this would be ok with a single belt, it's a 5 HP motor, I don't know what the compressor head is rated for.
