This is awesome thanks for posting, I have just bought a pack of the same rods and was going to try this next. Could you add a photo of the tip you used? Are your rods the 2mm diamter ones?

Rods are 3.2mm as stated in instructions above. The tip I used with the best result is on the right. No luck with the soldering iron style. I’ll try using hardie flex as a base next time. The finer the torch flame the better I think. It’s a fine line between too hot and not hot enough. Cleanliness is the key. Even the file you use must be clean or use stainless steel wire brush.

From memory the jewellers used an LPG and Oxy set.

That gets them a very fine flame hot spot.

The blue part of the flame would have been barely 2mm long.

The Strata 67 technical leaflet advises to use a carburising flame which means they recommend oxy/acetylene for the heat source.

Thanks Dave, I wondered what that meant.

I have oxy, so I might give that a go.  I'll need to keep the heat down though.

Marty, see what smaller welding tip sizes you can get to suit your torch. Tell them what you want to use it for so they can recommend the right size for the job.

It's the neighbours oxy but it lives at my place, it has a box of all different tips which I'll check out.

I can get my hands on a jewellers oxy set hasn't been used in awhile but should still be okay. Carburising flame don't bring the flame to a crisp cone so you are running a little more acetylene much softer flame.
