Got out today.
@Parm. Your call saved me going into another shop.
A decent roofers bit and brace. Needs a clean. But the jaws work and it has decent springs.
Smaller versions of the adjustable spanner. The jaws will need work. But I know hoe to get it done now.
GWR 3 Way carriage Key. Not for me, but for a friend.
Finally.
I meant, this.

Well, it was sitting there all alone on the shelf, surrounded by those common fellows from Calor, so I thought I'd rescue it.
I have the notion of getting the right neck and burner for a bit of silver soldering and hopefully achieve a sufficiently high temp for some brazing, which according to Sievert's bumph can be done at 720degC, so that opens a door or two. Propane is dead cheap and if it means I don't need to get into an oxygen cylinder rental or contract, that's fine and dandy.

You’ll struggle to silver solder with that, not impossible but difficult.
No way is that going to get anything hot enough for brazing. I’ve tried and failed

I find it unlikely that Sievert would be claiming 720degC when it can be easily demonstrated that they're full of it, if that wasn't true. They're not some anonymous ebay seller claiming the earth, and everbody knows they're to be taken with a pinch / barrowload of salt.
Whatever, if it does some silver soldering, that'll do me. I don't have much to braze, and in nearly all of the instances I would think of brazing something, a spot of silver solder would do just as well - fuel tap mountings, small pipes, etc.
See for yourself...

Were you using the correct nozzle? There's a fair choice.

I’ve got five or six different nozzles on the older model of that torch. I can see the claim now. Silver solder on jewlerry probably quite possible. I tried silver soldering something a bit bigger and it failed miserably.
Never managed to braze anything with just propane

Made some small brackets to hold the LED light panels in place till we work out what the ceiling in the garage will be finished with and i have to say i am very happy with the lighting compared to all the strip lights we used to have and they use a lot less power, I also got a tap that heats the water for the cabin that only had cold water, It cost £30 and just needs power and a water feed, It is quite a treat in this weather to not have frozen hands.

It came with the 7kW torch head, and I've got my eye on the cyclone burner with 10kW, so that should get things going.

Let me know how you get on, if it works it’s a much cheaper solution than having a bottle of O2.
Particularly interested in its brazing capability

if using propane then a cheap way to get it hotter is V in a couple of psi of compressed air....makes a massive difference to the flame temps

Sounds interesting, something I’m gonna have to try

How would you do that exactly?if using propane then a cheap way to get it hotter is V in a couple of psi of compressed air....makes a massive difference to the flame temps
I’ve tried brazing with propane and got the rod melted but couldn’t get a flow as I couldn’t get the metal hot enough.
I remember at school brazing with natural gas and an air pump of some sort (long time ago now) but this idea sounds similar.

That's a handy idea. These things are never to be found when you look for them ( I mean, buckshee, of course).
In the same line, I was looking at jeweller's reflective soldering and brazing blocks which are pretty much the same thing, and easily available.
