I saw ur video once before and just spent hrs trying to find help on getting mine going. I set up the gas 1st then air. I c I was wrong. Something kept telling me to check your post. Thankyou. I think i also need to switch my tip. I wasnt mixing the air and gas before ignition.
You can try two coats of a refractory cement over your fire wool. That should help protect the wool, improve the isolation (allowing a higher heat and great efficiency), and prevent small pieces of the wool from flying around and becoming an inhalation hazard.
I couldn't help but notice that anvil stand, made from a sawhorse. How is that working out for you? I have been using a trash can filled with compacted sand. While it has proven to be a stable platform, it is very difficult to move around.
Also, I am happy to see that the hair dryer will work, since that is what I am using now on my charcoal forge. I am in the process of converting to propane, however, and it is nice to know I can use the same setup.
who told u to do this things like this???? it cant work!!!!! i have already buildet a lot of gasforges, but non of my forges does look like so much like sh*t like this. if u want, i can help u to build a real working forge!!!!! send me a privat message, and can give u a lil video of a real working forge! which u can build at home with low budget.
@naabtalschmied Did you watch the entire video? It actually does work, though it isn't very pretty. I have also seen very similar homemade forced air/gas forges in operation and they work quite well and even generate enough heat for welding.
Hi I really enjoyed your video ?Can I ask where I could find the propane nozzle/orifice and handle set up?What size is the orifice etc? The HOLY SHIT part was hilarious LOL
@maxey83112 No, that's not galvanized. You are correct that galvanized metal is very dangerous when heated, but I used black iron pipe, definitely not galvanized. Thanks for your concern, though.
@pcblah Haha, I tried that on my Charcoal forge, blew the top off on the test run (thank god it was hot). Let that be a lesson, limit your beer intake when building a forge.
I was told to look up this kind of a forage due to me wanting to be able to melt copper to form ingots. Do you know if this kind of a forge would be able to melt copper? and if not do you know of a forge that I could make that would be able to melt copper?
@MuscaVolitans I had it made out of heavy steel pipe, I think it was schedule 40. If I had it to do over again, I would have used an old propane can or a freon can. With the insulating blanket and the satanite coating I've installed, the forge I have is ridiculously over-built, and a thinner metal container would do just fine.
I've had some problems with excessive heat, also. I would recommend a lower setting on the air blower, obviously. But I would also angle your furnace to where your air flow is directing up, as opposed to downwards so it doesn't melt your air supply and the passage carrying the air flow.
@MuscaVolitans I did make some alterations in later videos. I put a rheostat on the power supply for the blower, which has made an enormous amount of difference in how I can regulate the heat in the forge.
I don't know for sure how long a 20 lb tank of propane lasts. I had a 1/3 full can when I got the forge working, and I guess I've gotten about 8 hours out of that so far. But I'm still fine-tuning the air/gas mixture, so it may end up getting better efficiency. I know for sure that it's more efficient than the weed-burner setup I was using.
@thecustomart11 I doubt it, but I've never worked with a coal forge, so I don't know for sure. From everything I've seen, coal can get hotter easier (hot enough to melt the steel even), but it's messier. I don't have a problem with the mess, but my wife might :)
@captjeff78 Now that I'm more or less set up and ready to go, I need to do some actual smithing. I think I'll start with some small-diameter mild steel and try to make points, curls, etc. Thanks for your comment!
It would be great if you could cut the welds and spin it around so your inlet is pointing straight down. There is always a hot spot with forced air, but you can use that to your advantage. Forced air rules over venturi hands down...
@ArtistBlade1972 I'm definitely going to do both: spin it so the inlet points straight down and put some Satanite on top of the kaowool. For now, I'm going to spend the weekend making some knives and curlicues and decorative stuff. I need to just practice the basics for awhile. Thanks again for your help.
@Makermook That's cool, you should be very happy with it then. looks like a killer little forge. 1 tip for ya, basically all hair dryers have low voltage DC motors that run the fan. They use the heating element as a resistor and a diode to make a half wave rectifier to drive it. If you have a small variable dc power supply you can get some relatively precision air control out of it. Just gut it and hook the power supply straight to the motor leads...
@RDPproject I don't know about a round insert. I'd still have to cut a hole for the flame inlet and I'd have to insulate the back wall. I think I'm going to buy some kiln cement ("Satanite" I think it's called) and line the inside with about a 1/4" coating. That stuff is apparently rated to 3000 F, as opposed to the 2600 F kaowool. If I melt through the Satanite, I think I'll just bag the blacksmithing thing and rent my kiln out as an auxiliary sun.
its a little hard to tell from the video but it looks like you need a pressure regulator on the propane. those tanks have around 60 psi in them but with the forced air you can use as little as 7 psi. that might also solve the problem of burning the insulation.
I worked around industrial kilns for some time and I can tell you that the blanket refractory material won't last any time at all. There are soft materials that can be packed in where the blanket is that will last a lot longer than the blanket. We use to try all kinds of products, but nothing would last like plain old fire brick. only problem is sometimes it is very difficult to get installed. I think the plastic type would be best for you if you can find some.Good luck.
@RichL123 I've been thinking about that. I also wonder if I ought to get rid of the fire brick. I also need to fiddle around with the output nozzle and see if seating it further in or out of the 3" tube changes the burn pattern on the inside...my aim would be to eliminate the hot spot that hits the wall and melts that fabric.
