can anyone confirm the thread size of the gib screws on an imperial Myford vertical slide...I think they are 2ba...... Also the size of the two cheese head screws on the top of the slide...

Cant confirm but i did have metric on my old ML7.

See if an M5 screws in more than 1 1/2 revs.

The Imperial gib adjusters screws and locknuts are 2 BA, same as the older ML7 lathe slides. The 2 screws holding the bracket to the body are also 2 BA, x ½" and are usually socket cap screws, not cheese head.

If you have problems sourcing either, drop me a message, I've probably got some left over from my days as a Myford "fixer"

hi John

The cheese head screws that hold the feedscrew nut are 4 BA. Probably 3/8" long. Those are what you mean.

When my brain saw "top of the slide" it stuck on the feedscrew bracket as that's on the bit that slides up and down. Any other words ignored . Funny things, brains. indecision

In Imperial sizes Myford went for 2 and 4 BA for screws and bolts less than ¼", then either BSW or BSF, but to be contrary you might find a 3/16" BSW somewhere.

Caveat: on old Myford kit there is always the possibility that someone has changed things.
