Cross slide handle

Seems a daft question, but I cant see how the handle is secured to the cross slide lead screw. There are no obvious pins or grub screws, just solid metal. If it were just screwed onto the shaft then , even with a lock nut , it would tend to come unscrewed with use

Anyone any ideas?

Robin,

Here is a picture of the rather battered example on my recently purchased ML7-R

Just remove the Ball Handle and then unscrew the Dial.

I think that Robin was asking how to remove the handle as there are no obvious retaining fixings . Unfortunately I can't help as I don't own a Myford.

Robin,

Are we talking about a Myford ML7? You don't say in title or OP.

But if so, then put a spanner on the flats of the Dial, and unscrew the handle, usual way.

Well thanks for the tip, yes ML7 I didnt expect the mechanism to be so crude and that dial is pretty naff

In my machine shop years, I always worked on much bigger machines and never gave this trivia any thought

With an ML7 you have to be creative in unexpected ways

Cheers

Robin

I converted the handle on the cross slide of my ML10 to a Super7 type and converted a Super7 topslide to fit the ML10 cross slide so both feedscrews have resettable Super7 style index dials. Much nicer to use. I also made a reduction gearbox (2.5 to 1) to reduce the gearing on the ML10 saddle handle to match the saddle travel of a Super7.

Fair comment Martin ... it had been a rather tiring day.

The Ball Handle and the Dial just act as locknuts for each other.

ergo ... apply spanner to flats on Dial to hold it still; then unscrew the Ball Handle [yes, it's a right hand thread]

I wonder if you could upgrade by fitting the dial off a mini-lathe?

Naughty, Neil

... but there's many a true word < etc.>

At least you have a dial which some small lathes did not have from new. No need for one off a minilathe as hey you've got a lathe so make one. Remaining question is whether you have the wit to design one or need help there.

For general information there are a few machine tools where the securing screw goes all the way down from the ball end so might be overlooked as not seeming to be connected.

To be serious, for a moment, George Thomas designed both adjustable dials and a geared arrangement for the Myford topslide (in the Model Engineers' Workshop Manual).

You could modify the latter to use a suitable gear ratio so that it has very convenient and accurate number of divisions.

Neil,

I realise that they overlap, but: Your last post might be more relevant to Robin's other thread.

See my post in Robin's "Cross Slide Micrometer Wheel" thread (actually mine was from a mini-mill) .... cheap, easy to implement and it's resettable (which I forgot to mention).

From the Myford Ltd website:- **LINK** . Also available in metric and they fit the small vertical slides (That's what I've used them on).

Would this item on "the bay" be suitable? No. 321545610372
