I had both pipe vice on stand which formed part of a conduit bending

proposing is pretty trivial in the scheme of pipefitting. A word of
caution- trying to grip round steel pipe in a normal vice tight enough
to cut a thread will result in crushing it out of shape. I'd suggest
cutting your lengths ready to save time then hire kit over a weekend
to cut the threads. Are HSS still around in your neck of the woods?

Thank you. Yes - we have HSS but another company offers a pipe threader
at a more sensible £20 a day (rather than £87). Need to check with them
tomorrow if there are any extra charges for the cutters.

Is there anything special about the cutting lubricant? Or would I get
away with ordinary lubricants?

It's about 10 years since I did any thread cutting, but I think I used a
pot of tallow. You could just ram it over the end of the conduit.

Following up my own post, I see that TLC call it "cutting compound". They
wouls also sell you all the tools. A complete set for 20 & 25mm is £36 + vat
