For the benefit of @steve_s and anyone else that may be interested hear at some measurements of an extremely rare Harrison M300 rear tool post.
First the base:
Dimensions:
177.5mm long
82mm wide
46mm high from the base of the dovetail to the top.
There is a tee slot down the middle which on this one is just too small to fit a standard 1/2” tee nut, if I was making one I would make it to fit something I had around. This one is machined from a casting, I haven’t measured the dovetail but this should be easy to measure from your cross slide.
Now the tool post:
I have shown most of the dimensions in the picture, the width is 69.6mm and the tools are clamped in with 2x 7/16” bolts each.
There are also 3 x 7/16” holes through the centre to clamp it down.
Hope this is helpful.
