Details:
After decades of 'collecting', I'm having a thin out of my workshop.
This is a very high resolution dividing head - made (I think) from a 'kit' of castings (not by me, I hasten to add) to a very high standard.
The headstock has a 3/4" plain bore (with three radial clamp screws) and carries a 60 tooth worm wheel. The single start worm has the usual set-up of handle and dividing plate (with rings of 27, 32, 42, 50, 66 and 78 holes). The unusual feature, however, is that the dividing plate is carried on an arbor that itself has a 60 tooth worm wheel and can be rotated by a knob graduated 0 - 100. This means that 10 turns of the knob rotates the headstock by 1 degree - so the resolution (from the graduations on the knob) is 1/1000 degree!
Centre height is approximately 2", but with riser plates to take this to 3.2".
Tailstock has a 3/8" plain bore and is, currently, fitted with a centre.
Supplied complete with a 3.8" capacity drill chuck on a 3/4" arbor to fit the headstock.
Weight is nearly 10 kg for the complete assembly
