I used a milling machine on mine.
A drill press with a brake cylinder hone mounted in it on low speed would probably work.
A lathe might work if you mounted the throttle body in the tail stock somehow and your tool bit in the chuck.

Throttle body spacers don't do a damn thing on our trucks. Waste of time, money, and hood clearance.

Yup, TB spacers are just paperweights. On older TB injected vehicles, they would help a lot of the time. However, our trucks are port injected, so all a TB spacer does is delay the air from getting into the intake manifold by an extra millisecond. That has no positive effect whatsoever on the truck, sometimes even having an adverse effect on performance.
