Since I live in Mexico, my best option for making a forge is a lime-fiberglass mixture featuring a bit of cat litter for extra adhesion. At least it lasted me longer than pumicecrete. Pumice despite being a decent insulator, will melt and slag.

B & B Forge It'll be great. It sat with the space heater aimed into it for something like 8 or 9 hours after the last coat was packed in there. I figure after a couple of days a low heat to test it should be plenty and then I'm getting a piece of steel in it.

Did you use ridgidizer first or satanite straight over the wool? Looks like "thinset" concrete patch/leveler. Thanks for the vid, look straight forward.

It was rigidized befire it shipped to me. If you're starting with fresh kaowool, a spray-on rigidizer should take care of your prep before applying refractory.

so why wouldnt you use a rigidizer? like a spray? doesnt it do the same thing? im learning how to build one.
@drstrangefart

Rigidizer only stiffens the sheet of kaowool a bit. It does NOTHING to stop the ceramic fibers from being blown out of the forge into the air. The refractory is there to keep those fibers from being blown out. You do NOT want to be breathing those fibers unless you're a huge fan of mesothelioma.

Nope. If refeactory wasn't absolutely necessary to working safely, no one would bother. It would be WAAAAAAY easier to just slap new kaowool in and spray it every so often than dealing wirh refractory on every relining of the forge.

how do you glue ceramic wool to the sides of the forge?
@drstrangefart
2 жыл бұрын
The wool stays in the shape of the forge once you unroll it inside the forge. Then it stays put. The refractory is there to keep fibers from flying off the ceramic wool and going in your lungs.

@@drstrangefart my forge has a size of a big box so I need a way to glue ceramic wool to the sides somehow. it will not just stay in place by itself. also I need a way to glue it on the lid part of the forge. my forge is 100x50cm and 100cm tall. the iron I wanna work with will be on the bottom, but I made it taller so the top part doesn't get too hot. how should I position air intake - blower, when I wanna use coal as a fuel?

Try holding everything in place with wire and spraying a HEAVY coat of rigidizer on it. That in theory should get it stiffened up enough that you can apply refractory. Your only other option is to weld some small pins to the inside of the forge to hold it up.

The first coat I left alone for a few hours with the space heater blowing into the forge. The coats after the first one go faster but you're still gonna want to let it sit for 2 or 3 days after the last coat to fully dry and cure.

Pretty much. You want ZERO moisture in that stuff. First time you fire the forge up after a few days of curing run it on very low heat for 30-40 minutes.

Eric Gordon Yeah, I've figured out that refractory is a temporary thing. It seems with legitimately heavy use you can get a year, maybe two out of a solid layer of refractory. This won't see very heavy use so I'd guess two years would be a very conservative estimate.
