Title: came out of a lot of Machinist tools
Post by: swervncarz on August 18, 2014, 09:02:09 AM

This came out of a lot of Machinist tools but I'm not sure what it is (http://i286.photobucket.com/albums/ll88/swervncarz/20140818_095711_zps4f93cd83.jpg) (http://i286.photobucket.com/albums/ll88/swervncarz/20140818_095645_zps0d5242fb.jpg) (http://i286.photobucket.com/albums/ll88/swervncarz/20140818_095711_zps4f93cd83.jpg)

Do all the jaws move at the same time?  Looks like something designed to hold rod of varying sizes within its range, quickly adjustable.  Milling machine fixture?

This type of small 3 jaw chuck is often found on small clockmaker's lathes - the fixture looks to have an indexing feature (the button on the side) allowing it to be used on a small mill to machine a round rod or component with a number of faces... Strip it down and see if there are holes in the circumference of the mounting bush....

The green paint makes it look like an accessory for a Unimat lathe. Maybe a rotary milling attachment. Worth lots $$ on eBay!
