Thread: Gas forge for heat treating?

I think you hit the nail on the head there, Tim. I removed the muffler and there’s a marked difference on where and how the combustion is happening. I’ll cut back the muffler a bit and open the mouth of the forge some too. In hindsight, cutting a circular hole at the middle of the mouth side would have been a better choice, as well as lowering the muffler.

I did leave about a 1/2” of tube sticking into the forge, there doesn’t appear to be any obstructions.

For how simple these tools are I’ve sure made a confusing mess of things. Learning a ton in the process.

Just my 2¢ .... I think the muffle is to big in diameter thus restricting the amount of air movement and creating back pressure on the flame/nozzle.

Ah, a blocked goesoutta. You gotta have enough goesoutta to match your goesinta.

Your gas is pushedinta and your air is suckedinta and then they have to mixinta each other attaproper ratio which would be possibly limited by your goesoutta.

Yesterday we fired up the maple syrup cooker at a friends house. The fire and heat wouldn't work right. It was very windy and cold outside so those were the first things we looked at.

The sap is not running strong here so we didn't have a lot to cook and left it to this morning to continue.

It ended up that the damper in the chimney was not indicating right and was restricting the outta.

After cutting the thing off and letting it fall back inside the firebox things got boiled by noon.

Had your honey yesterday morning on some toast, tasty stuff. Had waffles this morning, could of used your maple syrup , used some store bought stuff instead.

Been working on a 2x72 design, hopefully that will go better than the forge design.

A little update:

Hacked off a couple inches of the muffler, increased the mig tip size to .35” and did a little grinding on exhaust side of the burner, now all is well.

The grinder design is going well but not without many redesigns. At least with that I can post some pics before I actually even build anything and you guys can critique it, thus saving me money, time, heartache, and humiliation.
