Now I have a little time of for a few days I thought I would make a collet chuck for my bantam lathe, I have access to a CNC mill so I thought I would machine the end of some steel I have then nip to the CNC mill and program in the six holes required just need the correct PCD's to program the mill, but I can't seam to find any info that makes sense so I was hoping some one here has done this before and may have the relevant info, my plan is to make the spindle end then when on the lathe machine the the other end the same as my ER32 collets, any help greatly received.
Regards Alan.
