Last night I finally got my lathe's countershaft out.
It's FUBARed.
Then I remembered that Danny Shields had given me some bar stock last year when I was picking up the T&A. It's perfect.
So there's two pulleys and two stops that use set screws. The two pulleys have two screws each at 90 degrees. Perfect world I'd want two groves milled at 90 degrees about 1/8 inch deep. Obviously we're not in a perfect world right now.
I'm thinking mount everything up center punch all the set screw holes then drill about 1/8 inch deep. Sound good?
Standard cup point set screws are designed for exactly this
Tighten them "good'n'tight" then back off 90 degrees then back up tight again, you will get another 45 degrees rotation as it cuts slightly into the shaft.
Those cup point screws hold all industrial non-keyed shafts. Like billions in use every day. They are built into most pillow block bearings.

+1 to this
So what you're saying is I'm overthinking this.

Usually, which is impressive given the state you were born in

Thanks but not sure how that puts me against average people.
Having had the standard set screws work loose more than once, I always grind or drill a flat spot for them to tighten against.

Drilling a low spot for the set screw to dig into is the right thing to do.
It's not about coming the screw getting loose, it's about being able to disassemble it later after the set screw raises a burr.

Well since we're from the same state I'll ignore Patrick and go with that plan.

Is that the state of confusion or the State of SC. I'm never sure which.

Both?
