Blacksmithing/building a forge?

>>1207352
Knock yourself out anon. I buikt a trailer mounted foundry.

Was gonna try the reil style burners. I hear good things and they cheap

Kast-o-lite 3,000 or kaowool unless u wanna throw an old brake rokor in the sink

I built a brake rotor forge, with a small electric fan. Don't go too deep for the fire box and buy good coal.

Can you take some pictures of it? Not OP but I was thinking I wanted to build a coal forge and am looking for ideas as well.

If you're using propane you MUST coat the high temp wool or you'll get silicon in your lungs. You do not want to get fucked up like that. My friend's dad died from silicosis and it was brutal.

Or you could skip the kaowool and use straight firebrick and refractory cement.

Reil burners are great for foundry work, but remember the magic number 450. That the number of BTUS that are needed per cubic inch of foundry/forge volume. A 3/4 inch Reil sidearm burner will produce about 150,000 BTU at 30 psi fuel output but you want it lower, so adjust your chamber accordingly.

Ever tried that? There are reasons the pros favor kaowool on their propane forges instead of firebrick. If you're nice to me I might even tell you what that reason is.

I sure do, waste heat, chamber radiation and insulation. Then again, a coating of ITC100 over refractory cement beats kaowool. But since you're such a pro, I'm sure you already knew that.

I was also talking about time to heat up, but I'm sure you knew that...

>>1208409
I said that. Insulation.

Again ITC100 is superior when you're talking about quick firing a large chamber because it reflects 90+% of the radiant energy that would otherwise be absorbed by the firebrick liner (or cement, if you went with that.) Kaowool helps limit the required thickness for the walls of the forge.

The only real benefit of the traditional kaowool lined forge is cost, since refractive coatings are usually about $80 a pint.

I never tried one yet bit good info.

Built a kwiky burner for my foundry and might jist use it.
