4 for 4 on removing broken studs today. I should buy a lottery ticket. 
For exhaust studs in a head? Yes you should buy lottery tickets or you've already used up your luck
Before and after. It seemed a shame that those beautiful castings had such poor paint on them. The paint would smear and wipe off with rag. I have a new cord with inline switch ordered.picked up some stuff at a local auction
I plan on trueing up some chuck jaws on the LeBlond lathe. I have a very nice Buck Tru-chuck that I dialed in to .0015" run out at the chuck but it has some "whip" to it. If I chuck up a round rod, it will run out .0015" at the chuck. When I check run out 6" away from the chuck, the run out is pretty bad.
I had removed the chuck from the backing plate and cut a light pass on the backing plate to trued it up. I was hoping that would correct the whip but it had no effect. I'll need to grind the jaws to clear it up. Not sure what I'll do with the tool post grinder after that project. I'll probably sell it. My neighbor has a nice Thermac tool post grinder here that I can use if I need to.
Tool post grinders are a lot of time and work to use on a lathe. Everything needs to be covered and protected from the abrasive grinding dust and cleaned up well afterwards. Otherwise, it's a good way to ruin a lathe.
I wasnt quite sure what that grinder was used for. After T said was a tool post grinder I looked it up.
I can see how it would make quite the mess on lathe Tim.

I picked up an old Columbian #504 bench vise. I was going to start cleaning it up. I spun the handle and the jaw didn't open, but the handle moved outward. Flipped it over and saw that someone had sheared the grub screw off from the collar that enables the jaw to move with the screw. No worries, I figured I'd just yank the screw out, follow by the jaw, clean everything up and slap it back together.
I was wrong. I guess whoever owned it previously didn't realize that the set screw had been sheared. That means that while the screw will pull the jaw shut, when you tighten, it will not open when you loosen. They had an ingenious method to get the jaws open. Beat that mf'er with a hammer. I'd imagine this what the after pics of a rob/ckelp rendezvous look like.
They mushroomed it better than 1/16" all the way around.
That's enough mushrooming to keep it from coming apart. Looks like some grinding and filing in my future.

Sounds like a girl you dated.
