I'm wondering if this tool post set:

will fit my Myford ML-7 lathe?

If anyone has one of these, can they answer a few questions please?

1. What is the ID of the mounting hole?

2. What is the distance between the mounting hole's center and the
closest edge of the release lever base? (Clearance for nut and
washer)

Thanks in advance.

That Web site says it uses a 10mm mounting bolt. - GWE

The absolute best tool post for a myford is a Dorian SD20.
THey might call it MD20 now.

Doug:

I have this QC toolpost on my Sakai (Toyo) ML-210, and I think it is
likely to be too small for your Myford. You should probably go up to
the next size in the Phase II line. I don't think the "micro" version
is going to fit.

The mounting hole is 14mm diameter top and bottom, bushed (I think) to
the bolt size, on mine 8 mm. However, there is absolutely zero
clearance betweeen the edge of the hole and the tightening lever
casting -- you have to use a cap screw with head diameter no greater
than 14 mm, and the head rests just below flush with the top surface of
the toolholder body. Plus, I suspect the bushing is either shrink-fit
or mechanically fastened in the bore, as it takes the tightening load
from the capscrew. If you bored out the bushing, you would have to
counter-bore the top larger to allow for the bigger capscrew head.

Repeat, you can't use a hold-down bolt that protrudes above the top
surface, as there is no side clearance at all.
