Broken Screw Problem

[Nipper123]

I recently started working on a Victor III I got for a good price but is in poor condition. I noticed that one of the set screws for the governor bearing was missing. Upon further inspection, I noticed that the screw had snapped in half and is stuck in the casting. My question is how should I go about removing this screw without damaging anything? Any help would be appreciated.

Thank you.

It looks like someone tried to drill it out. Typically, when the longitudinal forces are removed from a screw which occurred when the governor was removed, the screw should be free to turn unless it is bugged up or corroded. You could apply some penetrating oil and use a scribe to turn it out. If it is stuck, you should find a good machinist to get it out. It’s a fussy job, but not very difficult for someone with a vertical Bridgeport type mill and decent skills.

Where are you located?

I am located in Canada.

That’s pretty broad. There are machinists in the group. It’s best if parts don’t have to be shipped. Unfortunately, our USPS has become very unreliable.

Just because Canada is sparsely populated, doesn't mean that there are no good machinists here that are capable of dealing with such a thing.

Brian Nix is in Ontario.
I don't what he has for a machine shop and repair, it's a place to start.

I wasn’t knocking Canada’s machinists. I was trying to narrow down the part of Canada. If he was closer, I would offer assistance.

Sorry for the confusion, I am in Montreal, Quebec. Could I just drill out the rest of the screw with a normal drill if it is stuck?

Bob Nix. And according to the latest issue of The Antique Phonograph, he sadly has passed away.

Yes, you could do that. Use the tap drill size for that specific thread size.

The drill is likely to walk off into the soft cast iron. It is risky.
