I have a used table that has a problem with the motor pulley. The set screw is present but the brass pulley's threads are stripped bare where the set screw goes in.Because of this, the set screw cannot be tightened, and the pulley just spins freely on the motor shaft.
I have contacted the Table MFG and a new pulley is no longer avail.
I would like to get the pulley re-tapped on the opposite side so that the table can operate once again.
Anyone in here know someone who could do this for me at reasonable cost?
Follow Ups:
Use the existing hole as a guide, drill through the other side with the recommended drill size for the required tap.Tap the new hole running the tap at low speed on a battery drill / screwdriver with a slip clutch. Set the clutch to a level high enough to cut the threads but low enough that the drill stops if the tap binds (rather than snapping the tap which, being hardened steel, is fairly brittle).
Always use cutting compound. When the tap binds, reverse the drill, back it out a few turns, start again.
Sounds like a DIY project to me. As mentioned, the easiest way is to just go to the next larger size. That's a trip to the hardware store to buy a tap and a new set screw. You could also be a gentleman about it and install a Heli-Coil.
Remember how small the set screw is for a drive pulley.Helicoils require material plus they prefer a flat surface.
I Helicoil all my aluminum race heads if they do no come that way from the manufacturer.
You could probably take it to a machine shop locally. It shouldn't be much. Alternatively, you could epoxy the whole thing together yourself, being careful to keep the pulley in line. The revolver turntables just had a pulley pressed on to a metal shaft and it was common to epoxy them back on when they got loose. I would try the epoxy . Going to a higher quality table the Linn pulley is a press fit, ableit a very tight press fit. I have never heard of them coming off, probably because it is metal to metal.
It is generally easier to just go up the next size if possible. I can do this for you. drilling the opposite side is ok too. Just send me the set screw as well so I can measure the threads.
