howdy, lately I've been thinking about building a propane forge but before I start I thought i'd better check and make sure I was on the right track. first, is a smaller forge more efficient than a larger forge? common sense would say yes but what do I know lol. originally I was planning to use an old propane tank or a 5 gallon air tank for the forge body but got to thinking they may be larger than I need right now. I have some 8" wide pipe and I think some 6" or 8" wide tubing that might be a better starting option for me. second, not having any experience with burner
Hello everyone, im brand new to this site so if this is a dumb question please tell me. I need a couple fire bricks for end caps for my propane forge. Unfortunately in my area (SW Florida) it is impossible to find fire brick within 150 miles. I’ve found a few recipes for refractory cement but again the only materials I can find around here are Portland cement I-II, perlite, crushed silica, hydrated lime. Has anyone experimented with this recipe and would it suffice as a temporary fix until I can build a new forge properly?
Good evening everyone, if anyone in the MA or RI area is looking for refractory products I will most likely be going up to Woburn to purchase some Kast o lite, and some IR coating, if there is anyone that wants to go in on a bag or 2 of either I should be travelling up there week after next. If anyone in Northern, MA or southern NH is looking for refractory check out Cutter northern refractory, they have a pretty good selection of products.
Hello again everyone. I went ahead and got the refractory cement that was rated at 3000F for $5. I brushed, dabbed, and smoothed out my first coat. It is curing in the oven right now at 500F. I'm going to see what an hour does to it. I moistened the ceramic insulation first before I applied the cement. I read this is benefitial to help keep the fibers down and let the cement make a better connection. I will check on the forge in an hour and see if it will handle a second coat yet. Is it best to shut off the oven and let the cement cool down inside the oven gradually? I don't want to pull it ou
