Rear Tool Post - Myford Series 7 and Similar

Designed by Mr. G.H. Thomas and described in the Model Engineer, March 1976.

The virtues of parting-off from the rear of the cross-slide need hardly be mentioned. The casting (suitable for the Myford Series 7 lathes and others with around 3.5" centre height) bolts to the boring table and supports either the GHT designed steel turret with 2 different parting blades (1/16" and 3/32" wide) or the alternative "Riley" turret (pictured), which accepts one parting-off blade (3/32" wide) and one standard lathe tool (max. 1/2" square) that can be precisely indexed in seconds. Very useful for chamfering, form tool work etc. Maximum diameter that can be parted is Ø2".

The kit includes casting, fasteners and springs, together with all steel required to complete either the GHT or the Riley turret. This kit has been drafted from a 3D solid model and full drawings are included. In particular, the design has been revised to allow the GHT turret to accept the modern day 1/16" wide x 5/16" deep parting blade. Further advice on parting off can be read in GHT's book "Workshop Techniques" available in the apprentice's library.
