Clamp Knurler Repair

[Frank S]

jjr2001 you may be looking at this from the wrong perspective. instead of trying to drill and tap into the end use a pin wiht a large head then grind a flat so it cannot turn then hold it in with a dog ear from the side. the body of the clamp has a lot of meat on it you could drill and tap in the thicker part close enough to the head of the pin that a washer would hold it in place.
Just get you some drill rod or even a couple of old broken drill bits large enough to make the heads out of then heat them up and normalize or anneal them turn the pin then re harden them

Hello JR,

I'll search around to see what can I find in inch size, dowel, drill or an end mill. There is a shop here that has old stock perhaps might has something? Thanks again for the idea!

Cheers
