Re: Reducing Size
Chuck it in a lathe, turn it down then rethread it. Guess drilling the hole bigger is a no go?

Re: Reducing Size
TTOP is correct. Take it to a small machine shop and I am sure they could help you out. If its a hardened stud, they may make you buy a new cutter though. What is that a stud for?

Re: Reducing Size
Make your own lathe with a drill, vice and a file.
Put the drill in the vise.
Place the stud in the drill.
Spin it up and work it with the file until the appropriate outside diameter is reached (might take a while depending on drill speed and the file used).
Run your die down the finished stud.
Alternatively, grind it down with a bench grinder. Precision isn't paramount but you can get decent results with a steady hand.
I've done similar.

Re: Reducing Size
Do you have a technical school in your area with a machine shop? Take it there.

Re: Reducing Size
I did this a couple times, but i used my angle grinder w/ a 4" wheel to "turn down" the stud. The i just re-tapped the threads. Worked better than i thought as both threads are still holding fine.I wouldnt do it for a high torque application, but that stud goes to the carb linkage, so should be fine.
