Throttle Shaft Bushing Cutter

I needed to replace the throttle shaft bushings on a Rochester Quadrajet.  I know, everybody does as well.

But I’m cheap.

Actually a pretty simple tool:  3/8″ rod machined down to 5/16″ to pilot the cutter by the center bushing location.  Flutes cut with a Zip Disc.  Back rake cut with a file.  Works well enough to cut aluminum.

Bushings tapped in with a hammer, using a 5/16″ bolt as a driver.
