I'd go with the 5/8"-10 ACME. Is it a left hand or right hand thread? I have made a 1/2"-10 ACME for a friend's Atlas, and another's cross-slide screw of 5/8"-10 ACME, both left hand threads so I have the inserts for it and some nice 5/8" TGP (turned, ground & polished) 1045. I also have a threading tool for the 5/8"10 ACME internal thread, and a tap for the 1/2" version.
I believe you have a DRO for the machine, so the dial accuracy isn't critical, right?
P.S. - Yes I did see the link and ordered two of them, just in case I lose one in shipping. For $0.66 each, it won't break the bank and shipping will be quite a bit more.
Ken,
Turning the dial one revolution advances the cross slide in .100 so that would be .200 on diameter, right?
It's a left hand thread. I do have a DRO so dial accuracy is not critical. I'll get started on the drawings for the lead screw and get them sent off to you followed by milling the surface for mounting the nut so I can get you the center height dimension.
Let me know how much I owe you and I'll get it sent off immediately. You don't know how much I appreciate this Ken.
