Yes - I had the complete kit for bending conduit and threading it. The floor standing bender included a special strap vice to hold it without damage for threading. But the whole lot cost an arm and a leg.
Have been looking at prices - a lot depends on whether I am willing to wait on delivery from China!
Also, the difference between a simple 20 and 25 mm set, including die stock, and a ratchet device is considerable. I found one simple one below £20.
I really have little enthusiasm for learning welding at my stage of life. Having watched people doing it - real life as well as TV - I think I understand why people do it. But just not for me.
I have threaded 3/4" galvanised by hand.
Eight threads by hand is not a problem: Put you weight on it and it's work, but not hard work. Using (clean) motor oil for cutting will be fine; use plenty, and reapply. A pipe vise will make the work *much* easier. If you use a regular vise, perhaps you will need a helper with a long pipe wrench to counteract the cutting torque.
Cut the pipe using a "pipe cutter for galvanised pipe", one of those roller things as for copper pipe, only heftier. Pleasure to use: perfectly square ends, no outside burrs, quick, silent.
And there are/were chinese knockoffs of that kit in the 30? range -- though the one time I tried to buy one, the lady behind the counter said she wouldn't guarantee the dies for even the few threads I needed. (She told me leave a deposit and ID, and take this 400? pro tool and bring it back clean and whole, and she'd know by the state of the cutters if I'd skimped on the oil so don't do that, please?)

You really need to get the types used by electricians as they have a guide sleeve. Because they generally hold the conduit horizontally a normal die stock is hard to keep perpendicular to the conduit the guide sleeve helps you start the thread correctly thus preventing a drunken thread. Practically foolproof but no doubt some of Adams apprentices might prove me wrong.

Thank you - very helpful and interesting.
At the moment, I am thinking that for Mach I, I'll get the pipe supplied threaded. Then, maybe, switch to 25mm pipe if I decide to go ahead with Mach II, III, etc. Or at least, I'll understand what is possible.
ock, and a ratchet device is considerable. I found one >simple one below £20.

Yes - the inexpensive one does have guides. Am well aware of the need for g ood alignment. Thanks.
Bloody hell, are you building a Lockheed Blackbird?

Not using titanium!
Unless you are already a welder, I'd say it would be cheaper to buy all the pipe kit than to learn to weld to an adequate standard. Square tube with knock in inserts might also be cheaper.
Could you not find a local firm, plumber or electrician, who would do what you want for a price ?
That is my view of myself!
I don't want to go square pipe - but ap[preciate the suggestion.
Yes - once I realised the problems/cost of doing it all myself, that was what I initially expected - supply and thread. But am having difficulty finding anywhere willing to do that.
Supply unthreaded - no problem.
At this moment, I think I might simply pay for threaded and re-think for any future projects. For just four pieces (eight ends) it would be less expensive than buying the kit.
