Wheel repair; Dumb idea?

Dumb idea?

Old school American Racing Torque Thrust wheels on the 57.

9 or 10 of the screws holding on the spinners were broken off in the wheels. I got all of them out on three of the wheels. The fourth wheel still has three broken screws (8 x 32) that I cannot get out.

I used a “rescue bit” on most of the others. But, I am afraid my small rescue bit is now worn out. Rescue bits are not drill bits, but more like little bitty rotary files that cut through almost anything.... until they wear out. I used one to chip out an easy out and a broken drill bit from an old exhaust manifold off my brother’s MG a few years ago. But alas, I think I finally wore it out. They are really expensive ($150 bucks for a set of three if I remember correctly).

Thinking I will affix this last wheel to the drill press, then drill around the three broken screws with a 5/16 hole saw bit. After removing the core, I can tap for a 3/8 standard thread bolt. Will fill the hole with a hardware grade 3/8 bolt, cut it off close to flush, then grind it smooth with the surface of the wheel, then drill and tap for an 8 x 32 screw.

The larger bolt will be completely hidden by the flange on the spinner.

Dumb idea?
