What would you call this tool

[David KParticipant @davidk77137]

I bought this at Action a while back and don't seem to have any use for it so might sell.

Not sure what to advertise it as , it has a Parvalux geared motor so turns the chuck fairly slowly.

Don’t know but it is fitted with an expensive chuck!

[Ian Johnson 1Participant @ianjohnson1]

Looks like a rotary 4th axis for a milling machine. The tenon locates in the tee slots of the mill bed.

Looks well made too, and the chuck looks like a grip tru type and is worth a few bob itself, is it a 3 inch or 4 inch chuck? I've got a rotary 4th axis otherwise I'd buy it off you.

Powered spindle including 3j SC ?" chuck mounted on a tilting and rotating table.
You need to state some dimensions such as centre height when horizontal and degrees of tilt + and –

Looks like a Grip-tru chuck which is a bonus, useful bit of kit, especially with a stepper fitted in place of the fixed speed motor.

The yellow bit looks like it was originally from a T&CG and the motor has been cobbled onto the end, chuck on a 5C? or similar mount.

[Jeff DaymanParticipant @jeffdayman43397]

Maybe you could call it "Powered auxiliary spindle with three jaw chuck". I think it will be no problem to sell it – those that could use it would be glad to have it. Looks like good quality stuff.

Not sure what you'd call it as it's a bit of a home brew special.
I could be interested in using it in my own workshop though, as I'd been thinking about knocking up something similar.

Possibly a positioning aid for precision welding

OK interesting thoughts, thanks I will have to have a think about it now although

its probably a bit bulky for my mill.

I will make some measurements tomorrow .

My thoughts too, also consider it to be a set up to cut / grind some form of Helix angle on the mill.

I am sure Jason is spot on, very similar to the one on my Boxford T & C grinder — try Google " tool grinder universal workhead" and look at the images. The motor does look a bit of flash up but even so may well be original ? I can see a badge on the base in the first photo – a clue here maybe ?

Don't know what its for, but I have an identical Parvalux motor/gear assembly. It contains two worm drives, so the output shaft rotates very slowly. The worm drives are very good quality – the worm gears in mine seem to be chrome plated.

That's a powered work head for a tool and cutter grinder. It'll fetch good money if you put it up for sale.

David,

You have a PM

Looks very like a Cincinnati T & C work head.
