For sure - I've been scouting around for various JABOD designs - there's quite a range it seems. Some seem pretty technical ( for what is effectively a box of dirt) while others are literally three bricks and a trench. It may seem strange, but I'm almost more intrigued buy the forge build, than I am the forging....lol. I've gathered up my "scrap metal that might be a forge" pile, so that I can see my options.
LOL - yes - definitely kidding with gong to buy a special knife making-hammer - My primary mission right now is to have fun designing and building a working forge, then probably tweaking that design a bit, and then probably a bit more. I'm trying to avoid doing what I usually do - running out to buy "all the things" only to discover some of them are wrong, others are not the best thing and yet others never really get used....So, for this adventure, I'm actually trying to avoid the store - sort of a challenge - can I make this work with just what I can find on 5 acres.
I freely admit - I'm that guy. Not hammers per-say, but I've been known to be partial to a specific tool or device. Its bad practice of course, but I my have even blamed other "lesser" devices for my inability to get something to work. Some people say I'm just obsessive, slightly compulsive, somewhat inflexible, disliking of change and prone to think I'm right more often than reality will allow.....but those people are clearly wrong, obviously my success can by tied directly to the mystic powers of my favorite tool.
I do have a 55gal drum available. I had been saving it for pit-firing clay pots (another idea I've been wanting to try) but I don't have any clay pots, or clay, or in fact a kiln to bisque fire, so.....55 gallon drum is available.
A lot to digest there - but I think I follow. I thought about using firebrick, as you've suggested - but I only have regular brick (and a 1000 metric tones of rocks and boulders) laying around. I was under the impression you would not want to use regular red / yellow brick but only fire brick - is that accurate? If I can avoid firebrick I will - its not a cost factor, but I've set myself a challenge to try build this only with what I can find on the property - That said, I wont compromise the forge if I really need something.
Soil up here is not clay - our property actually sits on a gravel pit - or at least the same material that you'd find in a gravel pit. Digging here is NOT fun (installed 1700 linear feet or horse fence, 200 poles, never again). The composition tends to be rocky, gravel - little sand, not much clay. Lots of magnetic rocks...iron ore or something? Also have piles of 5/8ths-minus and arena mix (pipe bedding and sand mix) and also a pile of course sand (looks nothing like typical sand, but that's what its called). Have some typical "dirt" from old raised beds.
I little less clear on the hood idea - I had planned on something as a wind-break / Spark shield
I don't actually have an anvil - I was thinking I might use the a-frame "saw horse" thing in the picture as a temporary measure - Its very stout, the top is two lengths of 3/16 to 1/4" angle iron welded together - either that or I can use it as a tool holder?
