This little job is to facilitate the fitting of a DRO to the quill on my Warco WM40 turret mill, (bit like a Bridgeport)
Newall make a fitting kit circa £200 which 'plugs into' the front facing centre hole. This hole is just over 6mm deep.
, so I felt the fitting would not be very secure.
The idea was to replace the standard knob with a version that had a flat front (for screwing into) and would bring the face forward a bit.
A little bit of dismantling to get the old part out.
1. Existing setup
2. The old and the new
3. New one in place, but omitting all the other bits...so far.
