Hi,
I'm looking for some (Stainless preferred) M8 threaded rod with a left-hand
1.0mm pitch. Google hasn't turned up anything....Anyone know of a supplier for one 1000mm long?
Cheers,
Michael

Arun fastener is where I've got LH studding (plain steel, cos that's what I wanted) and LH M8 nuts. Mind, they were both M8x1.25
contact details on here:
I think the OP's request will be difficult to accommodate. He's after three unusual traits all in one part: stainless; left-hand thread; fine pitch. You're only allowed one of the three. Have a look at
Probably be cheaper and quicker to buy a metric screwcutting lathe.

Pessimist! 10 metres of stainless bar and about a gross of dies......
Die box and a post hole borer?
Mark Rand RTFM
When was the last time you saw a fine thread left hand post hole borer ?
Or even a post hole borer with 127 translation gears

Actually it's for a lathe. Looking to replace/upgrade the leadscrew on a Unimat SL

If you know where to get that number of LH dies without spending the national debt, I'd like to know.
have enough trouble finding ordinary M8 LH ones.
Have you tried Tracy Tools of LH Threading tackle? Thier catalogue implies they have LH stuff. I bought lots of RH taps/dies from them in the past.

Michael,
Since you are scratch building this it might be easier to change the design?
Do you really really need a thread length of 1000mm? Or would a metre rod threaded 25mm either end do? Really really need stainless? Why is 1mm thread crticial to the design?
Regards
Steve
In a previous post he said it was for a Unimat lathe cross slide. Mind you at one metre travel for a unimat it would make a good video to mate one of these with a TOS SN50

But then: Why 1m and stainless? I could turn you one in free-cutting steel at a SL-fitting length (if I have a mating nut).

I thought it was for that submarine of his! Missed the post in the middle.
As John said it for the longitunidinal leadscrew on a Unimat SL so the specs are out of my hands.
For my subs, you have a acrylic water tight cylinder (WTC) that has to be true at both ends. My subs require WTCs that are around 700-800mm long and so I'm looking to extend the bed so it can handle 900mm tubes.
And the reason I said stainless is purely 'cause I don't want it going rusty so that can be ordinary steel....
Michael
Thanks Nick but I'm looking to extend the bed to handle 900mm tubes (see my other post).
Cheers,
Michael
About 750mm is the maximum I could handle with screw-cutting. Dammit, my lathe is too small again. :-)
Nick
SS will be a lot harder on your half nuts. how many supports are you fitting?
