Collet system for Emco-Maier 8 x 18 lathe.  Cast iron backplate, bored while mounted to the lathe spindle then permanently shrunk to an ER-40 collet holder with the rear part sawed off.  Takes standard ER-40 collets from 1/16 to 1 inch with no gaps in coverage.
 
   
 
Temporary collet system in Sheldon 11 x 36 lathe.  Another ER-40 collet holder with rear portion cut off.  Holder is dialed in to desired TIR (offset or centered) in four-jaw chuck.  (Shop-built carriage stop/indicator holder is below.)
 
   
 
Yet another mill vise stop - can be rotated and/or moved sideways without changing the relative position of the stop.  Stop rod obviously can be moved in/out.  Can be rotated out of the way and returned to position and maintain relative position.  Vise is slightly modified for the stop as shown below.
 
   
 
After indicating the vise parallel with mill travel, the front jaw is removed and a skim cut taken at the vise stop mounting surface so that the stop will always be perpendicular to the vise jaw, no matter to what position it has been adjusted.  (A ground washer adds enough spacing to clear the front vise jaw.)
 
   

There is a spot of spilled paint on the side - no idea where it came from
