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 about rigidizer and that wool insulates better, etc. So we are wondering what we should do. I think we are going to line it and try a thin layer of the cement on the bottom to test the cement and to see how well it adheres and such to the wool. We just need advice and tips, what we should do, etc... We haven't built one of theses before (Obviously) but we have built a brake drum open forge. The other thing we want to do is to use a blower and coal rather then propane because we have a TON of coal. We are making it so we can use coal or we will be able to switch out the fan for a propane burner. We are going to have a rounded bottom in the forge, rather then flat so that when we put coal in it the coal will make a flat bed to put the steel/knives/etc. on top of it. We have put the face of the forge on a hinge so we can open it and clean it out, shovel the coal out, etc. Thoughts on this? The last thing for right now is that we have seen people put a hole in the back of the forge, and we aren't sure if it is for anything other then just long pieces of bar stock, so insight on this would be great. And, literally anything you could tell me about blacksmithing! Any tips, tricks, advice, literally anything would be helpful. We have a shop with lots of tools and machines, and we have both done a bit of blacksmithing, but I want to really expand my blacksmithing knowledge and skill this year, Thanks!
Ok, so me and my parter have made a few knives and are happy with our results so we think we're ready to move onto forge welding and making some demascus. I've got a pretty simple design in my head. I have an old propane tank I can cut the bottom and top out of. Going to cut a hole it, shove a weed burner in it ,fill it with a firebrick/ refractory cement mixture up to the lip and coat the outside with kaowool. I don't like doing things twice so I'd like to do it right and I've heard that most fluxes can tear through basically anything pretty quickly so I've done some research on materials I can line the inside with to protect it. Mostly what I've heard is there's nothing to do accept touch up the cement periodically, but I recently ran into a product from a company called homesaver that's used to line fireplaces. It's called "Flue goo" and I've heard a few smiths say it's suppose to be very resistant to flux. It's about $30 a gallon so I'd like to know if anyone has any experience with it and if so is it worth it? If not is there any other products you suggest that would protect the inside of my forge?
I recently picked up complete Buffalo #3 boilermaker forge and have found some info stating that it should be lined with refractory clay or refractory cement. Where can one get these refractory materials, locally in the PNW? How thick of a layer is needed? Should the cement be formed around the tuyere to create a fire pot? Here's some pictures:
