Bertie: my lathe is an Emco Compact 5. The only tools I have for it, apart from metric drills, are a set of 1/4" tool-steel ground tools, l/h, r/h and end, made for me by a friend I used to work with, (ie: ground to shape).
They work, but need to be shimmed up to centre height.
I'll try and take measurements off the lathe, like what size tool will fit, and the clearances you mentioned on the drawing, tonight, once the loft has cooled down a bit.
I'll also try and further identify the milling machine, but I do know it has a co-ordinate table with it. I have a collet chuck and full set of 25mm collets, but no LATHE collet chuck although there is one on e-bay at £56 at the moment. I could also do with a fine feed attachment for the milling machine, it has just a lever at the moment, like a pillar drill, which it greatly resembles. It also has a decent 0-10mm keyed chuck for drilling etc.
Thanks.
