Buying a lathe with a job lot of tooling and this was among it. I can't work out what it is!

First reaction is that it's a spin indexer but not too sure.

That was my first thought, but what's the big spring for??

I'd say it has a detent of some sort. from the 20 degrees on the plate I'm guessing there is 18 clicks. the holes make me think there is a rod for fitting in for turning it.
is the centre hole tapered? does it go all the way through?

Sorry, I should have added more detail. There's no detent, and the bore is straight. I thought it looked like a 5c indexer, but theres no taper for the collet. The spring is very strong. Spinning the end doesn't seem to adjust anything either.

ok. so that's a no then.

my other thought was a carriage stop. still need more information though. like what lathe is it?

Strange item. I am guessing maybe it isn't complete?

 

[novocaine]

well as it seems we are at a loss at this point (someone will know I'm sure)
have a look on here for your lathe and see if they list accessories.

Kinda reminds me of a magnetic clutch, like you get on AirCon pulleys.
Do lathes have such things?

The lathe is a 13" harrison. Picking it up on Sunday. Only thing it's really missing is a 4 jaw chuck and the honking great c spanner for changing the chuck. Quite excited as I've never had a play on a big lathe before, only my dad's Drummond that throws it's belts off if you make more than a micron cut.

Further looking at the "mystery thing" it looks like it was maybe bigger and has been milled down to fit something. I'll get some better pictures.
