Roy, thanks for making these videos! I find them extremely helpful.
Exactly what I was looking for. I've got an oil drum bottom blast hearth which I need to 'tweak' and this answered my question perfectly. Thanks Roy.
Great info about fire depth
Very good imfo,Thanks...
The 2 inch rule its ''good'' with antracite or i need more. Im in the prosses of bulding my a new fire pot and i dont found a great source of information about this setup. Merci beaucoup for your video i found it very informative and sorry to right like a 4 year old boy. From a 32 year old french Canadien Blacksmith
Awesome tip that will make designing my forge easier and cheaper
Good information if one is using Bituminous coal. If using other fuels, the ratios change based on the fuel properties.
Thanks for the video..
6 inches is ridiculous deep. That means if you are not going to dunk the iron into the pot like a spoon into a soup, it seems way too much. In eastern europe there is an unspoken rule of at least 5-7 cm of coal underneath the iron with more on top to cover it. It's a good minimum and enough for basically every handmade piece. But if you have like 6 inches of coal underneath just working as base between the air and the iron on top of it, it's pretty much a waste of coal and could get problematic with slag and dust at the bottom of the pot.
Great tip, not really quetion i asked myself sofar,thank you!
I work with charcoal so there's no coke in my forge but my firepot is almost exactly to your dimensions,oh,the only reason I use charcoal is regular coal just isn't available here...and thank you both for all of what you do!
I started to think that myself. Found tons in bags at a hardware store. But I can also order by the truck load. I don't forge enough for that. People use it for heating. So you could call some of those places.
If you have a coal fired power plant close by you might be able to get some from them too.
I forge with nut Coal or rice coal can be got at TSC it's anthirite coal for heating houses is the main purpose.
@@lanaholmes7098 I got some rice coal. Man is it ever dirty. Clinker heavy! It's what they call it "blacksmith coal". It's just the dirty leftovers stuffed in a bag. I prefer the stuff sized around acorn sized.
Best of both worlds.
Well, you've answered many questions I've had been having issues with. My pot is just the right size. But I can cut down the bricks or add more to deepen the pot. Next up clinker braking device. Slide or spin.
Went with spin
Would you say there's a correlation, though, with the speed and volume of air being blown through? i.e. would a 6" deep firepot require a bigger air blast to heat stock laying across the top compared to a 3" deep firepot? My firepot is 4" deep and I always have to work hard to get my heat all the way up to past the top level of the firepot when working with longer stock I'm laying down in there. I do run a charcoal forge, though, not coke, so that may make a difference.
Thanks, very helpful. Quick question, do you use nothing but coke or do you use coal as well?
I like 4-5 inches for general work.
Roy, I have a question, since you and WRABA have the same forge...Does your forge have a fire pot in it or did you add one? the reason why is ours has a flat floor and then the air grate comes in from the bottom. Our secondary forge is the same as your main forge, thats why I was asking.
if you just remember that a 12 inch rule is basically 300mm (305mm) you can half that for 6" and so on
What do you think about using anthracite coal? I don’t think that stuff cokes up.
Hi ! Great great video ! Thank you ;)
I tried to learn to forge by myself (and youtube oc ^^ ) and after your video i have a question, isn't it more difficult to a beginner to choose the no-pot option ? Because we dont control the coal/coke "transformation" gestion and all that ? Didnt a firepot help the beginners by it shape to control the fire and learn to manage the coal ?
Sorry if my english is bad :/
What about a side flow. I'm thinking about building another 1 and making it a side flow
Cutting to the chase: 8" square, 6" deep.
Thanks for the info.....came at just the right time for me. Now that n.California has stopped burning maybe I can start my own in my new fire pit . Unrelated question i have a wagon wheel tire,turn of the century,half in.thick,3 in.wide,bout 30in high. Any guess what sort of material that might be? Thanks.. Brian
Cut helf way through it and black it. If it's got a grain in it that looks like it strings. Or look up what wrote iron looks like. Cause it might be that. There are a tone of videos on here that shows u what it looks like when you brake it.
its probably wrought iron and of decent quality
Would a 30cmx30cm And 10cm deep be a good firepot
Las dimensiones serían iguales para usar carbón vegetal?
I have a plow disk that I want to make a forge. Will this work or do I need to add something to make work?
Huxley Harter So basically add another piece of metal to the rim to create a lip?
6" is roughly 150 mm and 8" is a little over 200 mm
Just did the conversion as I'm building mine, I don't have any rules or mesure tapes other than metric 😅
Not a professional by any means but 6” seems to be quite deep. If the largest stock you would forge is 1” diameter using your example with 4” of coke as a bed then a 4” pot depth would be best as pushing your stock below the top surface of a firepot would cause your stock to be at an angle and therefor limiting the cection of the stock you can hear as well as having very uneven heats across a section of stock. On top of that if you do have a 6” deep pot and you slide your stock in parallel with the surface of the pot you now have 6” of coke below your stock which seems to be a waste. Maybe I have misunderstood your explanation. Please help me.
Yes that's correct. 6 inches as a base under the iron is not necessary. 4 inches of coal between iron and air is already quite something and can be used for larger pieces.
You 're writing with the wrong hand.
