Cutting a LHS thread on a rod
I'm going to make a linkage rod. To cut the 5mm LHS thread can I just turn my die anti clockwise or or I need a LHS die?

Reminds me of the young chap on his first day told by the 'old hands' to go to the hardware shop and buy a left-handed screwdriver

As a 16 year old first year apprentice I was given a docket to get a 'Long Wait' from the General Stores. I fell for it.
Never got me again though!

Re: Cutting a LHS thread on a rod
I cant seem to get the die to cut the thread on my rod I've angled the top so it will go on but no luck.
Could it be because I bgt a 5mm stainless steel rod , for strength, when I should of bgt mild steel? Doesn't seem able to cut the metal?

Re: Cutting a LHS thread on a rod
Stainless is a pig to cut a thread on. Just use regular mild steel rod...

Re: Cutting a LHS thread on a rod
if your cutting ss.The rod will have to be well within tolerance of the die you are using.if your cutting a 10mm external thread,the rod has to be 10mm o/d
You can get away with alluminium or brass.SS and mild steel not so much.
If your rod is within spec, bevel the edge slightly.Use cutting oil and a lot of downward pressure.(I presume rod is vice mounted) If you cant get enough
purchase with die holder,You can clamp 2 vice grips to die handle,or holder to start off.

Re: Cutting a LHS thread on a rod
Get a length of mild steel rod
Stainless steel is a ba$74rd to cut a good thread on, you are more likely to ruin your LH die.

Re: Cutting a LHS thread on a rod
I started down this route until I realised that ‘turnbuckles’ are available in tons of lengths for a few pounds. Great for making adjustable length rose jointed linkages.
