    Blade broke, don't know why

    Hi, I'm fairly new to blacksmithing and I don't know where I went wrong, but today I broke my blade. I was flattening the handle of a drop forged wrench, and I put it in the forge. It's bituminous coal and I use a hair dryer attached to a pipe as an air source. It gets the metal orange-white hot. I took it out after 5-6 minutes and I noticed a chip out of the blade, it was the spine so I dismissed it. But as I started pounding, a crack appeared that ran next to the chip from the spine to the side that the edge was going to be on. I don't know where I went wrong, but I have a few therioes. The first is that, since I didn't brush the blade each time before I pounded, that I pushed some of those chips that fly off into the blade. Another theory is that I left it in the forge for too long and it got too soft. A third is that, instead of just pounding it into a blade shape and then trying to get it longer, I should've pounded it into a long, rectangular shape, like a piece of barstock looks, then formed the blade shape. Sorry for such a long post, I am just angry that I broke my blade and I dont know why it happened, and I don't want to do it again. Any help would be appreciated, Thanks!
  2. So basically, I built this forge out of an old aluminum grill top. My hopes were to use this as a small coal forge for bladesmithing. My question is, will the aluminum shell be able to withstand these temperatures with proper insulation? The shell is approximately 28" wide, 20" long and 8" deep. Essentially, I did a 3 inch layer of pea gravel on the bottom, around a black steel air intake. I used a mound of foundation sand for the pit, and filled in the empty space with a clay top soil. I'm pretty confident that this will be sufficient insulation on the sides/bottom, however I am concerned about the lip of the shell conducting heat. It is slightly raised above the pit and is as close as 8" in parts. I have included a picture of the set up. This is my first forge and I would love some experienced advice. Thanks in advance.

    Antique coal forge

    I'm looking for some help identifying this forge I recently picked up. Instead of a hand crank, it uses a lever/pump action to move the blower. It's definitely been repaired on top at some point over the years as it looks like the pan probably rusted through. Everything else is in original shape and works great, although the legs are pretty wobbly at this point. Should I restore them and make it usable again or leave it as-is and sell it to someone who needs a decoration? The hand crank mechanism works, ie. it blows a bit of air, but it's a lot more work than turning a hand powered version, even one without a flywheel. Just seems very over complicated and inefficient, which is why I'm wondering if it's not somehow "special." I can't find any identifying marks anywhere except for a 526 and 527 on either side of the tuyere. I hadn't ever seen anything like it and figured it had to be worth something!
  4. Well I recently finished up my third forge and thought I'd share the build with you all as I think it turned out pretty well. Sorry about all the pics, but everybody like pics right!?!? Back in about 2007, I built a real nice propane gas forge for my very first forge, and while it worked well, I quickly realized that I needed something that could handle a wider piece. So about a year later, I ended up making a simple coal forge from a wheelbarrow tub and a clothes dryer blower. I figured I'd make something simple, quick and cheap... then when I get more experience and could figure out exactly what I wanted in a forge, I could build one specifically to suit my needs. Well I finally went and did it, and I took pictures too! ... Lots and lots of pictures... To reminisce... here is a picture of my first gas forge, and also my simple wheelbarrow forge. Now, let's get on with the build! I've always considered the the firepot to be the heart of the forge, so that's what I started with. I have a CNC plasma cutting table so I drew up the firepot in Corel Draw, then cut out the pieces from 1/4" A36 HR steel and welded it up. Then I drew up an easy to replace "grate plate" for the bottom of the firpot. I was going to just weld in some bars for the grate, but thought I could easily cut a new one when it gets burnt out, and just drop it in place like this. The extra thickness will help the firpot last longer as well. Next I drew up the floor pan and cut it out from 3/16" steel, then drew up the four sides, cut them out, and welded them to the floor pan. Then I welded on some legs from 2X2 square tubing, welded some feet on them, and added some wheels on the back legs. The finished floor pan height is 32". I tore apart my wheelbarrow forge and used the blower, tuyere, and ash dump from it since it would save time, and it already worked great. I do wish the ash dump was deeper, but I can live with emptying it more often. I also welded on some bracing straps to mount the blower directly to the tuyere. I was going to drill and tap some holes in the bottom of the firepot, but I couldn't find my tap and die set, so I figured out which position I wanted the tuyere, drilled some matching holes in the firepot and the flange, then cut the heads off some 3/8" bolts and welded them in place to use as studs instead. I used blue tape to hold the studs upward in place while I plug welded them from the bottom inside of the firepot. Worked great! Here you can see a close up of them bolted together, a complete shot of my firepot/tuyere/blower/ash dump assembly, and finally with it installed under the forge body. I drew and cut out a piece of 14 guage steel for an air gate, then welded a handle and a stop to it. CNC plasma tables sure are handy! I decided to weld on some bars to hold my tongs, shovel, rake, etc... from 3/8" X 1" bar stock. I put them on three sides since I wanted the versability to be able to use it in lots of orientations. I have these openings on all four sides so I can get longer stock, low into the sweet spot if I need to, but I still wanted to be able to close the openings if I'm not using them so coal won't spill out. (also... the opening on the one end farthest from the firepot is deeper and flush with the floor pan in case I ever want to clean out the forge by sweeping rather than tipping it over) So to close them, I made some sliding "coal gates" that can be partially or fully slid out of the way, or even flipped to the outside when I want to open them. All four of the coal gates are identical for ease of replacement. Then I welded in some cord hangers to hold the 20' power cable. I couldn't decide on where to mount the power switch since I wasn't sure which of the 3 sides I would be using as the front, so I decided to attach the switch to a movable mount that can attach to anywhere on the forge body. I also used flexible steel conduit to help protect the wires from heat. And here it is all finished up! I painted the firepot and floor pan hi temp black, but painted everything else industrial grey since that's what I paint all my home built tools in. I also made a removable support extension for long stock that can mount anywhere on the forge body, and also stores conveniently on any side when I'm not using it. It's exactly 24" long and 12" wide to double as a measuring tool if needed, plus I bolted on a piece of broken measuring tape to it, for smaller measurements. Can't wait to fire it up!

    Coal at a good price

    This is my first post and I just started learning but found a good place to get coal if you don't mind a drive depending where you live. It's in xxxx, colorado. Probably a bit of a drive but their coal is $100 per ton, just call xxxxxxxxxxxx at xxx xxx xxxx. Follow their menu to purchasing and they will direct you to the person to buy through. I'm not sure what kind of coal they have as I haven't managed to pick any up yet. Once I do I will update everyone with more detail.
  6. Looking for somewhere I can get coal without the hassle of buying bags or shipping. Anyone have any leads? Thanks!
  7. The following is a quick summery of the 55 Forge. More in depth design and discussion can be found on the site. The original 55 Forge was bottom blast. The fire shown is a little shallow, so if there is a question, just add more fuel. The tuyere was a piece of auto exhaust pipe with 1/4 inch holes to accept 1/4 inch round bar in a X pattern to form a grate. Lots of open room for air to move up and into the bottom of the fire. The next test modification was to put a brake drum into the 55 forge as a fire pot. You can see the cone shape to the ash and the rim of the fire pot. The bricks were added to give the fire more depth for the project at hand. Ash will build up to the top of the tuyere in the bottom blast in a fire or two. There is a T configuration below the bottom of the forge that is not shown. The T section is close to the bottom of the forge and the down pipe is 12 to 18 inches long (what ever you have on hand). Clinker is not really a problem due to the size of the tuyere. Just let the fire idle for a minute or two and the clinker will solid up and can be hooked out. Ash will at times fill the down pipe and need cleaned out. I have run this forge using coal dust or breeze. Once the fuel starts to coke ( a couple of minutes into the fire ) there is very little fuel that falls into the down pipe. The next modification was to make the 55 Forge a side blast forge. Just cut a slice in the side of the wall and add an air pipe. The depth of the slice was to the top of a house brick laid on its side. It was available. The fire shown is a little shallow, so if there is a question, just add more fuel. I like this design as it is so simple to build and works. That is an aluminum clothes dryer vent pipe being used to transfer air from the blower to the forge. With the side blast version the ash and any clinker builds up under the fire. On either 55 forge, the cut edges of the metal as they are sharp. You can roll them over, or cut a 2 inch piece of metal from the parent drum, fold it in half long ways, and place it over the cut edge of the metal pan. The 55 forge was developed so that any one in any third world country could have a forge with little or no cost. The forge runs on solid fuel, coal, coke, wood, charcoal, lumbar, pallets, etc. As has been stated many times before, Fuel does not make the fire hot, Air makes the fire hot. If there is a question about how hot, then add more fuel and more air. It can and has reached welding heat. It has also melted the metal if you do not pay attention to what your doing. ( Do not ask how I know this as I was not paying attention.) The 55 Forge is a great design that is simple and works. It is easily modified to adjust the size of the fire pot, the depth of the fire pot, different tuyere configurations, and the list goes on and on. Folks thought a brake drum was needed, so I tried both a brake drum and rotor. Each has advantages and disadvantages and in the end were not required. It simply adds a level of complexity to the system and overcomplicates simple. The fun part of the 55 Forge is make one, use it, modify it as you wish. When you finish there is another 55 Forge on the other end of the drum as a spare. The label on a drum is NOT accurate, it only means that is what the drum contained just before the label was applied. I found a empty drum at a auto repair shop. The label said 5W30 motor oil with a brand I immediately recognized. Somehow the top of the drum was hooved or domed a bit. When I removed the bung plug from the bung hole there was release of pressure and an overpowering aroma of gasoline and other very volatile materials. I ask the shop manager about the drum and he said "Oh that was the one they used for racing fuel last weekend." ALWAYS choose a drum that you can pronounce what it contained before you brought it home. NEVER use anything that throws off heat or sparks when you open a closed container or drum. If in doubt, have someone else cut the drum in half while you go get a burger and fries for the both of you for lunch. The 55 Forge is just a way to get you started quickly, so you can play in the fire while you research and plan on what your second forge design will look like.
  8. Good morning all! I am new to smithing and new to this site. I am attempting to build a coal forge from some parts I have and want to get some feedback before I finish it. I had a metal cart and put in a truck hub into it. I notched out the sides to be able to put a longer piece in it in the future. At the Bottom, I plan to put a pipe feeding air with a tee in it and attach a blower to the end. The blower I want to put on a dimmer (not sure if this will work yet) so I can control the air flow. I already have the blower, just needing to buy the piping. Does this look like a good approach so far? What would you have done different? I left some room on the side of the pot to be able to put up some fire bricks to build a side/top if needed. Do I need to line the pot with anything? Thanks for the advice. Dave

    Fuel Supply - SE England

    Hi All, I've just started out, and the supply of fuel that came with my forge is very close to running out.... Any Smiths in South Central/South East England that have a good supplier?? I can't seem to find anything!!! Sorry if this has been asked before!! James.

    Forge Chimney

    Ok so I built a shop recently for blacksmithing. I needed to make a chimney set up so I took an old water pressure tank and used it as the hood. I have 6" chimney single wall going above the roof. The hood opening is 13" tall and about 14" wide. The hood is also resting on the forge. Anyway when I tried using it smoke did go up the chimney but some would puff out towards the top of the hood. The smoke buildup is not good and hard on my lungs. So my question is what am I doing wrong here? I did a little reading on threads and other websites about the chimney needing to be at least 10" or the hood needs to be lower. I can't make the hood lower without cutting more of the tank off because it is resting on the forge. Or should I scrap the hood and buy a professionally made one with 10" chimney?

    Brake Drum Forge Issues

    Hey all, So I know this has been asked before, but I am new to the world of forging and am on a limited budget so I built a brake drum forge, with a 1.5 inch flange and pipe welded onto the bottom, with the tee fitting to allow for an ash dump and an air supply (two speed hair dryer). I initially made the mistake of using anthracite coal, so I switched to lump charcoal, because I cant find bituminous. I am able to get the forge hot enough to bring my rail road spike up to a nice glowing red, but after the first heat it's a constant battle to get the spike back up to a good temp as well as getting a uniform even temp on the spike. Not sure what I am doing wrong, because I know it gets hot enough, I melted one of my spikes in half. I have spent almost 50 hrs trying to make a single knife, so I am getting discouraged. Any advice would be greatly appreciated.
  12. I decided to try designing a fire pot for my eventual coal/coke forge and I'm not sure if my clinker breaker design will cut the mustard. Does anyone have any input on if this design will work or experiences with a similar design? Any feedback is greatly appreciated. Best Regards, Jason

    My 'new' forge

    So I recently picked up a 'new' 2nd hand forge. From what I could see on first hand is that is is quite a good shape, the last owner said that his dad gave it to him brand new a couple of years ago and that he'd wanted to get in to blacksmithing, tried it out and found out it wasn't for him, and he had it sitting in his workshop for a few years and decided to sell it. I paid 165 euros for it and it works like a dream. I am extremely happy with my purchase, I practically stole it from him
  14. I've had next to no luck trying to find some local coal over here in Oregon, more specifically the Portland area. I've been buying my coal online for at least a dollar a pound! And it's really killing my wallet. Sure I can use lump charcoal for most things but it produces quite a bit of flaming debris, and getting a good forge weld is next to impossible. I've called every stove shop around and they've all stopped carrying, and yes I've called valley farrier (stopped stocking), mountain brook forge (haven't picked up phones in 2 weeks, sucks because they seemed like a real good option), central fuel in up in Chehalis (stopped stocking). I've heard of somebody down in Monroe that sells coal, but haven't got a phone number, nor do I know if he still does it. Ive made really sure to dig through all the forums and old threads before I started this one, I used the iforge iron function and the google :iforgeiron function. So can somebody help me either..... A- learn to somehow forge weld with charcoal? B- Find coal locally for a good price C- Give up and move to a gas forge? ps- I'm 18 years old and I'm trying to get into blacksmithing, none of my friends are interested which doesn't really bug me, I like blacksmithing because it's of the old world anyways. So I'd really to find some friends to forge with -Jonas

    Creating a firepot

    For those that haven't seen my post about me acquiring an antique forge recently, the picture of it is below. I wanted your advice on how I could make a firepot about softball sized with extra flat space (I don't know the specific name of it, like a table) around it for holding coal. Since my forge is a rivet forge it did not come with a firepot and with the tuyere about half an inch above the bottom of the pan. My idea was putting dirt into the bottom of the pan so it would fill in that half an inch under the tuyere. Then I'd make the firepot out of sheet metal. The pan is 18" diameter. Thoughts on this idea or if you have another idea?
  16. So to start off hello everyone, I've been trying to start, but i'm having some worries about how i can build my forge, at the moment i was going to use the box forge that's pinned but i haven't had time to build it, so my father decided to do it but it seems like he went a bit overboard this thing is absurdly large something like 3ft x 3ft and a foot deep and he used what i think is treated wood (I know treated wood had arsenic in it and couldn't be burned im not sure if its still like this today, but is it safe to heat it? aka being the box? ) now in the last few days someone heard i was trying to start blacksmithing and gave me a whole bunch of firebrick he had from a chimney or something, so i'm wondering is the box safe to use, or should i just do something with the firebrick? or line the box with it? sadly i don't have access to many tools or cash or i would have probably just rebuilt it or made something else but im hoping someone can let me know what i should do or at least give me an idea of a direction to head
  17. so, I just got my new forge built, but now after just 3 day's of forging, I am out of coal!!!!!!!!! GRRR if it's not one thing its another!! LOL I found a place that sells coal just down the road, but it is anthracite coal, and from what I read most blacksmiths like bituminous coal. I have NO idea what type of coal I have been using. I got it from a friend, who gets it from an old school boiler room. All I know about it is, that when lit, it smokes like CRAZY but after a good flame is created there isn't as much smoke, and it takes a little while to form coke. Also it doesn't "cave" like regular blacksmith coal. Got any idea of what I have been using? The closest place that sells bituminous coal is over a 2 and a half hours drive one way!!!!! and I can only afford a few bags right now, but later on I would like to buy a ton or 2.
  18. I am looking for blacksmithing coal in the chicago western suburbs. I have done an extensive search and I can only find coal in southern Illinois. I am hoping someone can help me find some coal locally.

    Beehive fire?

    I've been reading on techniques for using coal in forges and I read something on a beehive fire style setup. What is this? How do I do it? Do you recommend it?
  20. Greeting all! Just wanted to say hey. I have been creeping IFI for about 2 years, and then finally made an account about 3 months ago. Hobby blacksmith here. Have a small shop set up with a 132# Buckworth anvil from my Grandfather. Coal forge. Just hear to learn and find some others with like minds. I don't talk too much, mostly read and comment only if i know exactly what is needed being said. If you are within 100km of Lakeland County, would love to hear from you. Only know 2 other blacksmiths personally. Lyons Creek Forge down in Crowsnest Pass, and Frontstep Forge in Edmonton. Would really like to have another couple people closer by to bounce ideas off of....

    spark control

    Hello I just set a simple backyard forge up today and tested it out. I used some wood charcoal (i was unable to find any smithing coal) and am a little concerned about the three to four foot fountain of sparks that i got when my i started up my blower. Any tips or tricks to mitigate this? I am open to any advice or recommendations.

    Triumph then disappointment

    Well folks today was an interesting day. I recently picked up an old coal forge for 250$ CAD and was pretty excited to fire it up. Today I finally got the chance to do so and about 30 minutes into the session we heard a loud bang and watched a crack form into the cast table. Is there anything I can do to rectify this situation? I'm assuming considering it's cast welding is not an option. Maybe it would be best to just pull off the blower and attempt to recoup as much of my cost as possible! Maybe this is an omen letting me know I should switch to propane. Let me know what you think. Spencer Dirks

    Coal!

    Man oh man! I'm in need of some coal and can not find any. I'm in Florida so it's hard for me to get some besides eBay and they're proud of their coal! I keep reading that people are buying their coal for $50/ton! It's crazy and I would love to be able to buy from someone that can ship. If anyone knows where I can buy some please let me know!

    Oiled Coal?

    Hello! I'm new to the site and the trade! I was wondering if oiled coal has any disadvantages compared to non-oiled in a forge? Any help would be much appreciated! Thanks
