Scrapyard find !
Hi Guys,
Been nosing around the scrapyard again on Saturday and picked up this chuck.
19072015-013.jpg
It is an "EMCO" 55 mm diameter chuck. I spotted the name when wiping off the grease that was covering it.

This is the threaded bore, its quite pitted like the face, but the jaws move smoothly although they are a bit on the tight side.

The right hand picture shows the condition it was in when I picked it up. There are some holes in the rim, I'm assuming for Tommy bars to open and close the jaws in use. I've dumped it into a bath of diesel to soften the grease prior to stripping it right down and cleaning it up. I will need to find out what the mounting spindle thread is, though I could just grip it in the lathe 3 jaw to use it. I paid a quid for it (£1.00p)
I did have a hunt round about in the area where I found It in the hope that I might find the rest of it, but no luck ! It could have gone into the crusher or away to a smelter. I did spot a small induction motor that could have come off such a small lathe but its under some other stuff so I couldn't get at it.
Maybe next time.Best Regards:
BaronJ.

The chuck looks a lot like the one fitted to a Unimat3 lathe, made by Emco.
Its thread in that case would be 14mm x 1mm pitch.
The similar chuck for earlier Unimat lathes were 12 x 1, and have a separate screwed back mounting plate.
The jaws are unusual in that they can be reversed - there are no alternative reverse jaws, you just unwind them out and turn them around the other way.

Similar small chucks are also used on running centres. Instead of centre drilling the end of a bar the small chuck is used.
Just for clarification the chuck and live centre are a one piece unit, not a chuck plus regular live centre.…..Live a Quiet Life & Work with your Hands

Hi there, thanks for the thumbs up,
At the moment the chuck is residing in a bath of diesel fuel waiting for me to get around to scrubbing the gunk off it. Though from just wiping the face with a, damped in diesel rag, it looks to be very pitted. I hope that the scroll and the jaws are in better condition.
I'll take some more pictures when I take it apart. Pity I couldn't find any of the rest of the lathe. The guy at the scrapyard is going to get some of the material that is on top of, what I think might be the motor, lifted off so that I can get at it.Best Regards:

The teeth on the jaws are eliptical, rather than the usual crescent shape, to enable that.
You will find there's a particular sequence when loading the numbered jaws to the scroll, and it's different between the normal and reverse setups.
When you figure it out, write it down to save time next time!

Hi Guys,
Just a quick update. The guy at the scrapyard dug the motor out for me. Unfortunately it's not from an EMCO Lathe, in any case its no good the shaft is bent. So back on the heap it goes.Best Regards:
