wuzzuphupp Posted January 10, 2021 Share Posted January 10, 2021 Hello! I'm looking to build a forge and was thinking a Jabod forge looks perfect for what I need (cheap, easily constructed). Problem is, I'd been planning on using a wood forge, all the post I've looked at are for coal or charcoal Jabod's. I was wondering if anyone has tried to make a Jabod wood forge before? Would I just need to make extra space behind the fire pit for the wood fire and then pull the charcoal forward into the fire pit as it's made? Any thoughts would be appreciated!

Glenn Posted January 10, 2021 Share Posted January 10, 2021 You should make the JABOD Wood taller. That way the wood, to charcoal, to embers, conversion supplies forge. Link to comment Share on other sites More sharing options...
Daswulf Posted January 10, 2021 Share Posted January 10, 2021 One thing you could do is make a bit of a raised firepit and transfer the coals to the forge. You could do it in one with wood but it will be hotter to work at. Link to comment Share on other sites More sharing options...
wuzzuphupp Posted January 10, 2021 Author Share Posted January 10, 2021 Glenn, could you explain what you mean by "taller"? Daswulf, I was thinking of trying to keep it all in one spot, I can see the appeal of having them separate. Link to comment Share on other sites More sharing options...
Daswulf Posted January 10, 2021 Share Posted January 10, 2021 You could have it as a single unit and have a sort of heat shield made of sheet metal but leave the lower part open to rake the hot coals over as you mention. You may want to make the "box" part out of metal so it doesnt burn from having the larger fire. Technically a forge is just a fire raised to a convenient height, and air added to obtain the heat needed. Link to comment Share on other sites More sharing options...
wuzzuphupp Posted January 11, 2021 Author Share Posted January 11, 2021 I drew up a few ideas so you guys could get a better idea of what I was thinking. I incorporated Daswulf's idea of having a heat shield, although I think bricks might be a better option since they'd be more easily adjustable. Let me know what you all think, all the measurements are approximate and can be adjusted. Link to comment Share on other sites More sharing options...
Daswulf Posted January 11, 2021 Share Posted January 11, 2021 Guessing from the drawing it is a side blast? What is your air source and how big will the air pipe be? Link to comment Share on other sites More sharing options...
wuzzuphupp Posted January 11, 2021 Author Share Posted January 11, 2021 Yes, I was thinking a side blast, that's what I've read is most effective for charcoal. I haven't figured out what my air source will be yet, preferably something that I can moderate the airflow on. Any recommendations would be great. As for the pipe size, I was thinking 3/4" or something around there. Link to comment Share on other sites More sharing options...
Glenn Posted January 11, 2021 Share Posted January 11, 2021 Extended (taller) walls on the forge could pre-burn wood, to charcoal to fuel the forge. This is done separately from the forge now in a retort. Link to comment Share on other sites More sharing options...
Daswulf Posted January 11, 2021 Share Posted January 11, 2021 Side blast and around 3/4" pipe sounds good for a side blast charcoal forge. (Which is what you are making essentially.) The main parts will be the separation of the box for wood burning to make the coals/charcoal an the forge itself and how the coals get from the wood burning to the forge. I have some ideas about how a forge like this might work but it is really something I would prefer to do separately. In my idea for it you would have to stack the shielding brick bait high. In your plans is it just a single stack or it it a certain height? As far as a blower a simple bellows, rotary blower or a hair drier could work fine. You'd want more space for the actual wood fire so you get more burn and more coals. I wont lie and say it seems easier to have a retort and make charcoal or to transfer from a fire. Anyway it can be done as you are hoping. Just the efficiency depends on the design. Link to comment Share on other sites More sharing options...
pnut Posted January 11, 2021 Share Posted January 11, 2021 Simple solution. Build a typical jabod with a fire pit next to it and transfer the coals. You will have to build a woodburning jabod substantially deeper so the wood will have time to turn to coals. Basically a normal jabod with a couple bricks stacked on either side of the trench should work. I would suggest breaking the wood up fairly small too but like Das said a retort would probably be better. That way you're using two proven designs for what I'm assuming is your first forge. This way you won't have as many variables. Later when you get a good idea of what a forge Fire requires to burn and heat steel efficiently then the fun of experimenting will be much more productive.

ThomasPowers Posted January 11, 2021 Share Posted January 11, 2021 I prefer to not burn steel in my forge(s)! While having the wood fire right by you may seem like a good idea in January, in August the extra heat and smoke will not be your friend. I have a raised firepit I can burn wood in and move around so that it is down wind of the forge and anvil. I built a shovel to transfer coals "from the pit to the pot". It's made from rock shaker screen and so I scoop up a heap; shake it good so any ash and small bits stay in the firepit and dump it in my firepot. Bellows are actually easy and cheap to build---you don't need to use leather! A "double Lung" bellows was pretty much the blacksmith standard for the last couple of centuries.

natkova Posted January 11, 2021 Share Posted January 11, 2021 If you are building bellows dont go for."airtight light" material.it need to be heavy. I mean it must, or they wont work. Link to comment Share on other sites More sharing options...
wuzzuphupp Posted January 12, 2021 Author Share Posted January 12, 2021 Thanks for the input everyone! I wasn't planning on building right away (hard to dig in January) so I'll put some more thought into what I want. I'm also gonna have to check some city ordinances to see what's actually possible for me in city limits. Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 12, 2021 Share Posted January 12, 2021 No wood fired BBQ's in town? You may not want to share that you are BBQ'ing metal... Link to comment Share on other sites More sharing options...
wuzzuphupp Posted January 12, 2021 Author Share Posted January 12, 2021 Haha noted! Our neighbor down the street have a wood fire pizza oven so I know they're allowed, I just don't know what the requirements are. Link to comment Share on other sites More sharing options...
