8mm LH thread. Help

Can anyone help me locate some 8mm X 1mm LH allthread.


I fetched my little TOYO lathe out yesterday,first time in six year and after very little use yesterday the threads on the leadscrew hav shot it. They must have been on the verge last time I used it.



I know if I can locate a proper replacement the cost will be out of al proportion to the article.



If the worst comes to the worst I can always have a crack at making on on the Myford,but a piece of allthread would be a time saver.

Probably no real help, but I've got 5/16" x 24 LH die head chasers, I could easily knock you up a length at that. So near but yet so far No, I don't have a tap to match. :-(

are a good place to look, they sell a wide selection of special all thread, i have used them in the past on more than one occasion and they have suplied us with both twin start and left hand studding (all thread) .

failing that, you could purchase a LH die and make your own, although, if its a long lenght you require this may not be practical.

Don't forget to turn them t'other way when engaging, or else you'll get a badly chewed-up workpiece!

Just as an aside,Tracy Tools quoted me £14.40 for the die (hope the

read it was only 1mm pitch not 1.5mm).

The reply from the London Tap & Die company was that this was not standard item and would take a day to make at a cost of £25.00 pe hour. :rolleyes:

I don't think I can run to £200.00 for a die. :eek:

I bought some LH precision ground ACME threaded rod (3ft length) from MSC in the US for $US100 landed in New Zeland, for fixing my FiL's Chiwanese lathe crossslide. Geoff
