:lol: ask google they would give a better answer ound:.. But gas would be my choice

I use gas. A drop of soap on the alli and heat until the soap is black.

HTH

Gas as the heat soak on alloy will beat the heat gun also you need to get hot!

I go by eye but you can soot the panel up and burn it off to be a indicator of hot enough or soap or a match stick

Geoff, top tip with ally, use fairy liquid as an indicator solution, squirt it on and rub it all over and then use a flame torch (oxy/act), the fairy liquid will burn and turn brown at the exact temperature which ally become malleable

Well reading this thread this morning. I didn't expext to be annealing some alli.....

Had to pinch the washing up liquid from the kitchen...

I just use a bar of soap and rub it on in a few places much less messy

I don't find it messy. Just a drop where I want it. Run under the tap soon cleans the black soap off.

As a trained sheet metal worker(double curve including coachbuilding) I have my ideas and other people can have their ways, but you can keep your washing up liquid

With you on that one, can't help smiling at the rusty set of tools on the shadow board in most workshops

Alright then, the gas oven didn't go high enough to anneal aluminium. Not having a set of metal work tools I do my beast.
So what do you say I've got to use instead of washing up liquid.

Rusty tools. That's because you're too idle to wipe them clean after use and put them away in a locked tool box. I recomend Snap-On tool boxes as well as tools.

No high horse for me. I do not like somebody telling me that the use of soap of any sort is not for checking annealing aluminium alloy.
Please note I said aluminium alloy not not aluminium which is a base metal not an alloy.

As for rusty tools. Have you seen the state that mechanics sometimes get there tools in working in rain and mud at the roadside. So I learnt a long time ag, the late 1950's, that you clean things and put them away.

Oh yes. I have ALLOY wheels on my Defender. Alloy STEEL....

I will ask again
Saying as you DOWNED me about using washing up liquid for annealing aluminium alloy. As I do not have the use of a furnace I have to use other methods
SO WHAT SHOULD I AND EVERYBODY ELSE USE INSTEAD OF SOAP. ?
