Monarch CK Chuck Removal

The CK has a D1-6 spindle configuration. Came with, at first glance, a decent Cushman 3 Jaw Chuck. Still need to take a closer look at the chuck and maybe teardown and rebuild.

Needed a cheater bar, small 1″ black pipe, to slide over chuck key handles more for grip than for leverage. The cam locks were stiff but not stuck. Chuck came off with little fuss.

Greenfield Tap and Die (GTD) 1/2″ Self Opening Die Head

Not to be confused (as I did in earlier post) to the Geometric Die Heads.  After much digging around I have found tons of Geometric Die Heads, a few odd brands but nothing like the GTD one pictured below.

This GTD version seems to be adjustable over a particular range of diameters.  The markings on the chasers (the only ones with it) say 18 18.  Typical Type D chasers are specific to diameter and tpi – say 5/16-18 for instance.  This GTD version is marked 1/2″ so basically the 18 18 chasers would be useful for 5/16-18 and not much else I am afraid.

The D type chasers are available, yet to find the J Hook looking ones that are used in the GTD Model.
