let's talk about some of the differences between Coke and gas forges what even is Coke if you remember our video from visiting the Tata steel factory we referenced Coke as the fuel that they used to make iron coke coke when you take coal and you cook it you get to burn off all of the sulfur and you get left with a very pure carbon fuel that is known Coke so it's very clean burning form of coal and why we like it is because it gets really really hot in the gas forge I can get steel
a bright yellow close to a white in a Coke Forge I can literally burn the steel it gets that hot and that's exactly why I want a Coke Forge here I want to be able to have isolated very very hot heats for a little video idea I've got a gas Fort makes an enormous wide heat so heating up very specific areas is quite difficult and though it's fine for Forge welding Damascus you can run up to some limitations with other projects so now let's work out where we contain the fire now there's two main types
a side blast and a bottom blast in order for the coke to burn you need to have a continuous Air Supply in with a blower in the side blast it comes from the side you end up with a really nice hot spot here and then you work your steel right there at the top of the Coke and the pipe through which the air blows is called the twier which is the same word they use for the massive copper water cooled pipes that are pumping in gases into the blast furnace at tartar steel it all comes
around in one big circle now the other type of Forge the bottom Blast has the air being blown in from the bottom and includes a fire pot that's the fire pot so you have one little localized area of hot Cokes and the bottom blast always used to be my personal preference here in the UK you would see a lot more side blast forges that's a lot more common and popular here but in America the bottom blasts are everywhere [Music] foreign [Music] [Applause] [Music] [Music] little fire pot for our baby little Coke Forge now as you
can see we need a pipe that goes down beneath it that is going to form our Ash dump and it's also going to allow air from the blower to come up into the hot Cokes now I don't have the right size of square tube so I think we're gonna have to cut up some rectangular tube to make it into square tube [Music] so obviously if I was to put some coke in here it would just fall through it would fall right through so what we need is what's called a clinker breaker which stops the coke
falling through and allows us to break up the slag and impurities that form into what we call clinker it is a square that pivots it's going to sit in here and it's going to be able to rock back and forth clinker breaker foreign [Music] [Music] so the basic fire pot assembly is put together apart from the fact that there's no way for air to get in we've got some pipes they're smaller in diameter than I'd like they're two inch pipes I'd much rather have a three inch pipe the Saving Grace for this project however is
that it's a tiny fire pot one and I've got a really powerful blower on the way to arrive today so even though we're going to restrict the airflow a lot with the small pipe diameter I think we're going to be okay so in order to get air into the forge we need one of these pipes to be connected to our Ash dump with an appropriately sized hole but I also want to use the rest of these pipes to make a valve a gate valve so we can regulate the amount of flow because sometimes you want
to have very little air coming in sometimes you want so much air you blow that coke to the ceiling [Music] thank you [Music] now [Music] so we have a very quick and a very dirty homemade gate valve and this fire pot is basically done we just got to get it mounted wait Jamie uh why are you wearing a biking helmet [Music] well we have found that Jamie is a significantly faster driver than me I've got a motorsport mustache that's why yeah you know that is quite a speedy mustache [Music] so all this stuff is in
loose I don't even have any need to weld it down it can stay loose which is Handy if you ever want to transport the forge or these things get rusted out and that is something that I learned from Prime Brazil about his forges and considering I want this to be ultra light and portable I'm very happy that we could get it done with this thin sheet and so now the final I think step is getting our blower attached to it this is a bouncy castle blower they are unfortunately quite loud but they put out really
good amount of air and I always found that this is about the cheapest way to get an adequate blower for a Coke Forge you pick them up on Amazon think I paid about 50 Quid for it I know Amazon I also picked up this a little bit of air ducting aluminum will basically just find a way to duct tape this to that and this to the forge we're done and in perfect timing because Jamie has just showed up with our Coke he went to the dealer this morning it actually looks like Coke oh it's been
a long time since I've lit a Coke Forge let's see if I remember how oh it's so portable [Music] [Applause] [Music] [Applause] [Music] I don't even have a scoop I've got a dog bowl if I didn't have this dog toll I'd have to use my debit card now it's been a while so I can't speak from the biggest point of authority but this coke is very moist it's also just always very hard to light so you want to be very careful nice wood base uh big wood base to your fire before you even start trying
to put the coke on it you've got to steam off all that liquid before it's any use to burn so you've got to really get that Heat going in there I'm gonna now try put a little air through it get this wood burning a little hotter there we go that's what I'm talking about I don't have a rake who doesn't have a rake what blacksmith doesn't have a rake now I know it's an expression little cool kids are throwing around these days but I think that this Forge is lit let's heat some steel so in
a second here you're about to see some Sparks start coming up out of the fire and that's going to be the steel actually burning there we go see these little tiny Sparks popping up right here that's the steel burning this is what I was talking about this fire being so much hotter than a gas forge and you see if we take this out that is burning and molten steel we don't get that in a gas forge but we can in a Coke Forge we say we do a little forging Jamie now I found one problem
I don't have a rake so I'm going to make a rake foreign [Music] [Music] [Music] [Music] [Applause] [Music] foreign [Applause] I have a rake it will rake things and now I get to show you the one downside to Coke what a downside to Coke you see right now this fire looks very dirty well though it's a very pure form of carbon and it's quite a clean fuel it still produces that clinker I was talking about and so as it stands right now the fire pot is all clinker and Ash have a look at this that
right there at the tip of the rake clinker but our clinker breaker is useful because while we're forging we can do that can you imagine the hot coals all stayed in the top you can clear out the bottom of the fire while you're going and hopefully not have such a dirty mess you would then typically have a steel bucket underneath it so that you could dump the Ash and clinkers out I'm so happy to have a Coke Forge once again it's going to be very exciting this episode has been brought to you with the sponsorship
