thanks gents, yup - looks like the compound was at 61 degrees

i've also made sure that the tool is perpendicular to the work.

hi guys, any suggestions on the following strange threading results ?

trying my hand at metric single point threading on an old ML7

compound set to 29.something, half nut stays engaged.

stopping the lathe and backing out with cross slide, then back in to zero.

using a partial form insert.

the side of the thread on the tailstock end is more vertical than expected. what i expect is the top drawing, what I am getting is the bottom drawing.

any ideas ?

haha, bloody auto correct, and the ipad turned the photo upside down

love caking screw on the crash ss slide = locking screw on the cross slide

Does anyone know what the thread spec is for the love caking screw on the crash ss slide dial on a Myford ML7 ?

The screw measures 3.47mm, but I can't seem to find a match on either metric or sae thread gauges.

The screw that is currently in there engages in a m4 nut, but a m4x0.7 bolt does not go into the dial...

Thanks for all the info guys, much appreciated.

Any way of checking/measuring if the saddle on my particular lathe is guided on the front way or on both ?

Greetings. Recently got an early Myford ML7 (K2560), and busy cleaning and getting to grips with it.

I have been reasonably successful with the gib adjustment for the top-slide and cross-slide.

The saddle is giving me some extra grey hairs

I've taken it apart, and disconnected it from the apron. With all the gib adjustment screws slacked off, it moves freely across the length of the bed. I have also used a vernier to get rough measurements of the ways, and it seems pretty consistent at 4.494.

When I start by adjusting the screws (outside ones first as per manual), the saddle runs ok closer to the headstock, but binds toward the tailstock end ? If I adjust it to run free at the tailstock end, there is a noticeable back and forth rocking motion at the headstock side. Any suggestions or tricks to get this sorted ?

Also, what is the function of the ecentric clamp C33 ?

Lastly, could someone pls try to explain to me the best way to re-install the apron w.r.t. minimizing leadscrew movement when the half-nut is engaged.
