What would you do with this chuck?

[Janderso]

I can’t remember how or when it came to me. It must have been recent.
I took some penetrating oil and a scotchbrite pad to find a delightful surprise.
Cushman, Hartford, Connecticut. Model 5234b.
Maybe use it for holding a part in the rotary or milling table?
It measures 6.250” across.
That’s about the end of my creativity, sad but there it is.

Those two ideas both sound good to me, Jeff. With two adapters you could do both. You might be able to do both with just one adapter...

Thinking about it a bit more, you could have a locating spud to index it to the RT, and also a built in set true feature to get the center of the 3 jaw on center. And perhaps a custom bushing to fit the 3 jaws for locating the chuck center.

Do you do much welding? If so use it for a rotary welding positioner.

I second a welding positioner. Use a car front sealed wheel bearing so you have a through hole for parts. Make a housing for bearing and acts as a mounting flange to chuck. Take a old rotisserie motor from the barbecue and adapt. Motorized positioner

Yep, it depends on accuracy/wear (mostly in the scroll), as the jaws could be re-ground.

If in great condition use for machining.
If in poor condition then welding positioner.

I picked up a big (10 inch?) chuck at a yard sale when thinking about a welding positioner, but now I fear it's too big and heavy for that.

Chuck it!

Sorry couldn't resist. Don't do that. It should be useful for something. I agree weld positioner sounds like a good idea.

The 3-jaw that came with my lathe I replaced but ended up keeping it. It's my beater chuck that I don't care much about. Turned it into a "tap-tru". I use it when I need to do sanding/polishing. Chucks can act like a fan & sucks all that dust in so I use that chuck.

Build a rotary welding fixture......

I'm planning on building one soon with a 9" chuck and an old South Bend Heavy 9 headstock....

When you throw 'em right over the plate, I can't help but swing at 'em.

Yes, a welding positioner.

Nice "find". I would clean it up first. Then find out how good it is. There are many good suggestion above already, but if you use it for welding, I suppose you would shield it well from all the splatter. It looks to be in good shape.
