Reddit reviews MAGNA INDUSTRIES MT 245C High Intensity Pencil Tip Torch

I can't see your torch, but I'd guess it is too small. I've been dicking around and I've had luck with this one:

Lowes/Home Depot will not carry fire bricks in store. Call a BRICK store. Google your cities name and "brick supply" and call them up. About 2.50 per brick, and prob 10 bucks in fire clay if your setup will require it.

I had good luck with my paint can forge made from refractory cement. Not how it is meant to be used, but worked ok. Only used it for a month, so no idea on longevity...

I'm working on something a bit bigger right now...

Have you thought about buying the Atlas Mini burner and then just buying some fire brick and build something?

I'm doing stock removal, so a basic 2 brick forge and a larger pencil torch get's things hot enough for me, but I kinda regret not buying a better burner. Here is the burner I'm using:

I would have been much better off buying the Atlas Mini burner and adding that to my homemade forge:

Here's a great tutorial I used to build my two brick forge:

I built one of these for my first forge last year (except with kaowool for the insulation rather than refractory cement), and I had the same problem. I swapped out the small burner that came with the propane (I think it was the same model you have) for this torch, and have since been able to consistently get steel up to an orange heat. It was hot enough for me to make a bunch of knives, tongs, spearheads, and other small things.

I also had to buy a 25# propane tank, though, as the 1lb tank would get cold and lose pressure (which meant reduced heat) after about 20 minutes.

Would a torch like this work? or this one?
