[HELP] Suggestions for 3 jaw chuck lubrication

[Highpower]

The setscrews are commonly known as 'dutchman pins' that lock components together. I believe the plugs should be a snug slip-fit into the chuck body. Threading a screw into the hole and using a slide hammer should pop them right out if I'm not mistaken. A press fit would make lining up the forks around the chuck screws near impossible to do without them binding up the chuck screws. If nothing else you could always drill new holes on the other side of the plugs/chuck body and install new pins or screws after the plugs/forks are aligned properly in the chuck.

I had to replace the tail stock quill on my lathe and make up a new lead screw and quill nut for it. Same type of set-up basically.
