Dual Lathe Tool Height Setting Aid

[natie123]

Another lathe tool height setting aid. Not very elegant, but simple and quick to make. The base was cut off a piece of 30mm bms round bar, drilled and tapped for M6. The two tabs are 22 mm lengths of 20 x 5mm bms flat bar, each drilled through 6mm near one end. The gauge was assembled with 6mm threaded rod, nuts and washers as per Photo 1. The assembly is adjusted until the junction of the two pieces of flat bar is exactly at the lathe center height from whatever datum you choose (mine rests on the lathe saddle).
The bottom of the top tab is used to set the height of tools held in the front tool post (Photo 2) and the top of the bottom tab is used to set tools mounted upside down in the rear tool post (Photo 3).
