Topic tags/keywords: lathe

I bought this used lathe, I’m a complete newbie and I need to make sure I understand some of these parts.

Craftsman 113.228160

This part in particular. I believe the end of this is an MT1 cup center, missing the center point. If this is correct, then it is seriously rusted in there. I want to make sure that’s what it is before I start hitting it with Liquid Wrench and a mallet.

Put the liquid wrench to it for a while. If it is morse tapered there should be a hole through the back of the tailstock to insert a knock out rod. Gently tap from that end and it should come out. If you don’t have a knockout rod get a 10” nail and grind the end flat. Also some tail stocks will eject a centre when you retract the spindle all the way. I have no experience with that particular lathe but others should be along with specific experience. Good luck.

That is what it looks like to me. I would give it a good soaking in penetrating oil; rather than use a mallet and maybe mess up the quill I would put vice grips on it and try to loosen it that way.
I have a craftsmans dead center that looks the same and the hole on the side should be for a set screw to a moveable point. I would trash the dead center and get and new live center for <$20.
As rusty as the quill is I would disassemble and clean good or it will always be a bugger to move.

Edit> I had a Jet that looked about the same with the wheel for the quill in the tailstock body. There is a good chance the quill is not hollow (or hole through the tailstock). I would soak the quill good also before you try to move it much, the plastic wheel can be broken fairly easily if the quill is frozen in also.

Just checked the manual on vintage machinery.org. It is hollow and it suggests using a 1/4 dowel or brass rod as a knockout.

Thanks guys. That’s what I was going to try, poking something through the back. I just wanted to make sure I knew what I was looking at.

I’ve already ordered a live center, spur center and a new belt. Just have to mount it and find room in the garage and I should be in business.

What Bmezz said. When all else fails, read the manual:

From page 18:

5. To remove the center insert a 1/4” wood dowel or brass rod through the hole in the tailstock ram. Hold the center with one hand and tap the dowel or rod with a hammer.

Cheers,
Brad

Thanks guys.

I read the manual, I just wasn’t sure I was hitting the correct part with the dowel.

This is a spur that goes in the tail stock and has a #1 Morris Taper on it. It is wedged into thecylindrical tail stock (and probably rusted) so put a little liquid wrench on it wait for an hour or so and drive it out with a hammer and punch or similar device.

I sure hope the inside of the quill is ok.
