It will get hot enough to bend 12mm rebar easy.

Keep the heat localised with hardie backer board or similar.

I carry one in the work truck for stubborn nuts and things. Saves carrying bottles about all the time.

Yeah work got rid of all OA from the vans for insurance and provided them with these burners, which from a desk jockey point of perspective is good, but when you need to blow a bolt off to make the job quicker isn't such a great idea. It's not rebar that I will be doing not sure where thats come from, will be round bar and flat bar 50- 70mm width.

I do have a rothenberberg torch that's runs off the yellow map gas (not sure if there's different ones etc) use it mainly at work for warming bolts up but never thought to try how hot it qould get steel to bend.

it says hi pro mapp gas on my yellow bottle

ive heated a hub nut up to glowing red whilst on the hub just to get it off the car friend had damaged the threads and the hub had cooked the bearings that nut wasnt shifting
so gives you a good idea it did use 1/2 the map gas bottle though to do it

just buy 2 firebricks from local fireplace shop place the fire brick in a vee shape put the bar into it pref if possible off the fire brick and you will get it red hot

its best stood off of the fire brick but allows the heat to reflect back onto the bar

watch your blowlamp tips as they can and will over heat

Same gas bottle I have but different nozzle on so might look at that option,quite compact and would be ideal for what I need (hopefully) thanks for those

the blue gas bottle is the older type nozzle, whilst the yellow gas bottle is using the newer type of nozzle

the twin nozzle is not cheap if you have the yellow single nozzle it will heat it up well

only difference between the blue and the yellow one has auto ignition

Looking to do some bending of heavier guage material nothing above 10-12mm but I would rather hear it to make it abit easier.

At work we use the induction heater or oxy propane, but just curious what people use in their home shops, as my house insurance wernt massively keen on me keeping oxy acetylene at home for obvious reasons..is there a way to just heat with propane? Or other alternatives. Ideally like to keep the heat fairly concentrated rather than say using a forge which will heat a bigger area.

If I have something heavy to bend I'll use the carbon arc torch on my old buzzbox.
No gas costs, no bottles, nothing like that, and it's fierce.

A long time ago, I made a handheld propane Reil burner, for spot heating.
Simple to make from plumbing parts.

Id read somewhere it was round / rebar. May not be you posting it. 12x70 is a forge job id think.

oxy set at minimum.

I made a coal forge in an afternoon with scrap I had lying about. I have to take it outside because I haven’t made a hood / flue yet but it’s fine for what I do.

Got a load of 20mm round hot enough to bend by hand easily.

Flat bar works just as well in an induction heater. If you have a few bits to do forming a coil the right shape gives you a more even heat quicker
