I want a graduated collar to go onto my newly purchased Chester DB10. The one fitted goes in 0.04 increments (lead screw is 2mm pitch). My other machines have 0.05 graduations so it would really keep things simple for me if I could get hold of one. I know the Warco WM250 and other models are basically the same machine so a collar form them would work. Only prob is I am worried if I ring them and ask they will want to know which Warco lathe I have and obviously I don`t have one. Perhaps they will not be helpful with me because of that? Or if someone on here has Chinese lathe with 2mm lead screw and 0.05 collar perhaps they could share the model and year of it.I could download manual and look part up and ring them with part number.? I have emailed Chester but am awaiting reply but presume this is going to be standard spec and they might not be willing to supply me with what I want.

any help or advice on this would be greatly appreciated.

Ady.
