Hello there! New member here, me and my dad are in the middle of building a propane tank forge. So far it is all put together, cut open and ready for refractories. Here's our issue: He have some ceramic wool to line the inside, 1" thick. We know that it is better to do 2", and I think we have enough for 2". We Also have 2 5-gallon buckets of unknown refractory cement (We don't know what kind/brand it is, we just know that it is refractory cement). Our original plan was to line the forge with the wool, and then coat it with the refractory. But as I've been reading and looking around, I've heard
Hi. I built a gas forge from a paint can. A lot of shortcuts were taken to save time and money. Many things were not done quite right according to helpful posts in this subgroup. The forge was lined with a homemade refractory composed of fireclay, grog, perlite, wood ash, and concrete. When it was first built, it could barely weld mild steel. Since it was outside, it eventually rusted through and the refractory collapsed. Even after repairs, it wouldn't weld. Some colleagues wanted to use it, so it looked like time for a new one.
Another newbie with forge questions. Details: a. 20# propane tank b. Frosty burner Questions: 1. does rigidizer = colloidal silica? 2. how do i apply it? before tucking the kaowool into the tank? Any other tips for applying it? (Frosty mentioned sopping wet kaowool in one post, but i couldn't figure out the context. 3. What's the best angle to set the burner into the tank? I've scoured the archives and found answers to most everything else--Thanks all!! These are the questions that remain.
