Abwood machine vise screw

This PM I managed to break the screw on my Abwood milling machine vise (it sheared where the roll pin goes threw) . Measuring the thread it's 5/8" x 8 tpi acme.

So has any one got an old ML7 lead screw (5/8" x 8 tpi acme.) if it's warn that's OK as I only need approx 10".

Thank you

Ian

A Myford leadscrew is LH, is that what you want?

Mike

Aah, I never thought of that ! No it will not do the job. Will have to have a rethink.

Thanks for that info Mike.

Rotagrip have some new screws and nuts for Abwood but not cheap.

Years ago I repaired an old 4" Abwood by turning a new screw, 8 tpi was very simple on my Boxford. Doesn't need to be particularly tight tolerance on thread form, esp. if the nut is a bit worn. I used an HSS tool, hand ground.

I used mild steel which proved entirely serviceable for hobby use,although something like En8 might be a better material.

Just an update.

Kingston engineering show the standard length is 5 feet but when I inquired they replied they could supply 6" for £7.50 + £10 p & p + VAT.

But then following Clive's comment I thought yes I have a lathe, milling machine & Google so after a bit of research on the internet and a practice on aluminum I produced a new screw which I'm very happy with.

We knew You could do it, You just needed to find that out!

It was lurking inside that bar the whole time!

That's smart, well done! I didn't put a square on mine, just cross-drilled 1/2" for a tommy bar

The Abwood vise handle is a well designed item, so it would be a shame not to utilise it!

Is that left hand ?
