I don't own a lathe nor do I know anyone in the Portland OR area with
one. I did find a 43/64 drill bit at my hardware store which is 0.472 or
about 3 thou over. Is it feasible to use it and then use shim stock to take
up the difference? Or am I just begging for a wobbly pulley?

Don't do it.
Find a lathe and do it right.
Or find a local hobby machinist and spring for a 6-pack of his choice.
