Hello,
I was given an WMC FS-450-AN 8x18 Lathe. The lathe is basically a Taiwanese-made clone of an Emco Compact 8.
The Lathe has a 3 jaw chuck on it, but only has outside jaws with it, the inside jaws are missing. the chuck seems well made, and measures 4 ¼" (110 mm) diameter and has K538 stamped on it. Anyone have ideas on where to find jaws for this? I have contacted little machine shop to see if the ones they have may fit.
Thanks for any help

The Emco chucks that I have seen for the Compact 8 have three socket head cap screws near the center, like this:

I suspect yours is an aftermarket chuck. If it is Chinese (good chance it is) then good luck finding replacement jaws. It might be better to find a used Emco chuck. These have reversible jaws.

Check the mounting on your chuck, I suspect it differs from the original compact 8 mounting style. Your best bet and cheapest is probably
a new chinese chuck with both sets of jaws like Shars or similar

Thank you for the responses. To bad someone misplaced the inside jaws for the chuck, as it seams to be pretty good quality chuck. I will keep my eyes open for a new chuck. For the moment I am working around only having the outside jaws.
I am just starting out, so I don't even know what I don't know yet.

The chuck shown in your photo is for an Emco Compact 5. The Compact 8 chuck has 3 studs that are only seen from the back that mount to the DIN 55021 spec spindle b
