Do you think it would be possible to make something like that with a homemade bender? I'm talking about the angle iron design that fixes to a bench. I'd have to make some of the folds shorter in length to fit it in though. I'm not sure a homemade bender would be accurate enough, let me rephrase I'm not sure a homemade bender made by me would be accurate enough.
Oh and the post has just arrived
Big thanks to @Jim Davey for getting it out to me so quickly even with all that's going on with the website updates ect...

Jim needs to up his game sending out those girly purple tig torches. My first one was blue. He's turning us all into Jessie's
Just kidding mate that's a torch for life that. May she serve you proud.

I have a home made folder. It's good for 1mm stainless across its 600mm length.purples cooler than blue
should be getting it set up and tested soon. cant wait
Hey Richard, what do you use to bend your cases?

Well i got it all set up and tested however the flow rate seems to high.
Even with the pressure relief valve fully unwound I'm getting 1.4 litres per minute. 1 litre per minute minimum is recommended at 50 psi. I don't have any way to test the psi unfortunately and i don't know what the max pressure the torch can take is.
Do you think it's safe to run it with the relief fully unwound and 1.4L a min?
If not I'll have to T off a bypass back to the tank

Don't get so worried about the figures.
1-2 Lpm is fine and it's not gonna hurt even if you slightly step outside of that. I've made loads of the things and never once measured actual pressure. If it's making it out the other side and not bursting or bulging hoses Then it's fine.
What you have coming out looks fine to me. I'd even be inclined to increase it slightly up to 2lpm. i was running 2 Lpm ish through the rehm cooler I made. That was a procon set up.

ok cool, i was just worried i might damage the torch as the maximum coolant pressure is listed as 50 psi and also, i didnt know if having the pumps relief valve fully unwound might damage the pump or wear it out quicker, its literally one turn from falling out.

Wind it in more. You'll find the last few threads don't do anything to the pressure and like I say turning it up isn't gonna hurt anything. Go for 2lpm and don't worry about pressure.

I pressure test all my torches to 60 psi and even crap ones don't fail. Some of Binzel's new hoses are holding over 300psi in destructive tests so I don't think 1.4 bar is going to trouble your setup. The weakest link is the red and blue pvc extensions but they are internally braided and will comfortably cope with more than 60 psi warm.
You'll have no troubles.

This implies I sell some crap torches, I don't by the way. But I repair all sorts of mixed rubbish for clients, and if it won't pass the pressure test after a repair it doesn't go back.

Upped it to 2lpm and ran it for an hour with no leaks, cant wait to try it in action tomorrow.
It took less than 1 turn to add .6 litres , no doubt its a powerful little pump.
You werent kidding when you said these motors get hot, without being cased in and with the fan blowing across its side it was nearly to hot to touch. Hopefully i'll have enough airflow around it when i do get round to building a case, for now though its going to be open plan.

Don't cool it across the side. Cool it up the **** end. You want the air flow to get in the vents at the back. That motor won't come to any harm getting hot but it will heat up the brass head and anything else close by.
