Maybe some use?

I was about to suggest Marchantdice … but an internet search suggests that they might have disappeared.

Jimmy's link looks useful.

They have trapezoidal … but a search for ACME brings only one result; and I'm pretty sure that's wrong.

[the spec-sheet appears to show it having a metric screw]

Abbsac still list this as a "legacy product" **LINK**

Might be worth a call ?

Hence the usefulness of jimmy's link

The USA might be the only place to buy ACME from stock.

Oh!

At least you can get it!

I once ordered some BSW threaded rod, I didn't ask the price, as I'd had loads of metric stuff costing very little. I think it cost £20….lesson learned

I needed some 1/4" Acme threaded rod and could only get it from USA. Even with the postage it wasn't too expensive.

I have had acme feed nuts from Kingston, excellent products. Have recommended them on previous threads. Only problem with threaded rod is their minimum length is 3 feet. Another link **LINK**

Has anyone tried using McMaster Carr in the states . I did a dummy run on an order to find out shipping costs. When I placed the order it said shipping cost and taxes would be added ,maybe I'm missing something but it didn't show the final combined price ,needless to say I immediately stopped the order . Shame because the price was what I was willing to pay .

Sean

[JasonBModerator @jasonb]

By the time they had added taxes and shipping there end and you then add import duty, VAT and fee this end you will probably find HPC or one of the other UK sources cheaper

[Paul Appleton 1Participant @paulappleton1]

Mcmaster-Carr will no longer accept orders from the UK. Try finding a LH Acme 5/8×10 tpi leadscrew and nut in Europe!! The old Colchester lathe I have originally has a 5/8×5 TPI thread on the crosslide. This is not even mentioned in most data books. By replacing with a 10TPI I would have had a direct read dial. Wow! how 'modern' is that?

Kingston Engineering can supply 5/8x 8 LH acme screw and nut 'off the shelf' for around £50 total. But of course I then have to make a new indexing dial.

I realise that the auto feed rates would be affected by doing a conversion, but thats not really a biggy for me.

The reason is that it's a 10tpi pitch .200" lead 2-start thread.
