really sound like it was very familiar with the machine.

Drew,

I got the original screws somewhere. I will measure the TPI when I find
them. I'm pretty sure they were .100" per rev. The machine is pretty nice as
low-cost Taiwan iron go.

They use a strange mix of inch and metric bolts to hold it together. Some
dimensions appear to have been inch values when they machined the castings. I
know for sure the bolts holding the column to the base are 5/8 NC. I'd have
to say the leadscrew was designed and manufactured by the same persons who
came up with the bolting scheme. Kinda iffy. IMO, If you decide to go to a
three axis DRO, you'd disregard the leadscrews anyway.

The MSC people, they are lookin' at the same catalog page we are. Not much
help.
