  1. Hi, I was recently lucky enough to purchase a Champion 400 blower and Whirlwind firepot at auction. Both are in great shape, having just the usual rust, dirt, grease, etc. I do however need to make two adjustments to the blower. I've researched everything on the 400 on this site and others but can't seem to figure out the answer. Adjustment 1: I assume since the brass gear is concave on the working part that it should set directly above the worm gear. Mine is off toward the inside so that only the outside of the brass gear is touching. When looking down from the top, I can see a lot of the worm from one side and nothing from the other. I removed the set screw and tried to nudge the gears over but they won't move. There are a lot of warnings about forcing so I decided best to ask. So how do I move this gear over? Adjustment 2: The main shaft the fan is attached to has a lot of play. Everything looks to be fine so I figured I could place a 3/4" socket on the back and 1" socket on the front and tighten them together to snug everything up. They won't budge. And just as above, there are warnings about putting too much force on the shaft, so thought better to ask. So how do I tighten up the bearings? As always, thanks for the help and for IFOREGEIRON! Kent.
  2. In the process of reassembling my Champion No. 400 forge blower after tearing it down and cleaning it up, I managed to mess up the end of the large gear shaft and now I can't thread the cone nut on to it. Does anyone happen to have a spare gear shaft (the one that is 7" long that the large gear fits on to) that they would be willing to sell? I was hoping someone had a Champion 400 in bad shape that they scavenged parts out of. I checked eBay and there is nothing there. I took it to a machine shop and he said that cutting 1/4 to 1/2 inches off the end was the only option. Not sure that leaves enough threads on the handle end for the cone nut and top nut. I would appreciate any help in finding one.
  3. I have a Champion 400 blower that is in need of an overhaul and I need a little advice on part of the tear down. I've got everything disassembled except for the bronze worm gear. I can't seem to figure out exactly how it comes out of the housing. I've removed the square head screw holding the gear to the shaft, but my problem is that I can't see how to pull the shaft. It looks like there are two plugs on either side of the housing (under the bearing caps) that may come out with a spanner wrench of some sort (threaded in?), or maybe I need to jack one side out using the tapped holes. For anyone who is familiar with this blower, do you have any advice on how to get the shaft out of the housing? I would rather go into this knowing how it is put together so I don't do any damage. (Sorry, no pictures available, it was too late when I finished stripping the thing down.) John
  4. Today I want to share with you all the forge that I constructed from scrap lumber, steel fence-posts and wire mesh, all found around my house. The screws were mostly extras that my dad had laying around, and everything was done with minimal tools. I want to show what CAN be done, and that you don't have to go fancy to make beautiful artwork. First of all, after I first bought my Champion 400 blower and Whirlwind Firepot, I knew I needed a place to put them, so that I could forge efficiently. This was my original set up. I did work like this for about 6 or 7 months, which was a real drag. The fuel always fell out of the heap, as you can see from the bricks surrounding the pot. So, with a little help from my dad, we scrounged some scrap wood and built this table: As you can see, the forge is wood, with a plywood top and adobe/mud topped with firebricks. This was amazing, forging on top of this puppy. Unfortunately, the first forging only lasted a few minutes... We have smoke! Ignition! Fire! So, this forge caught fire. The plyboard was only an inch away from a hot firepot, and so it reached critical temperatures.... Back to the drawing board! I knew that I was not going back to this rubble pile of a forge. It was just plain inconvenient! So, I measured, and began to cut the fence posts! The fence posts spanned the wood, now devoid of the plywood. Note the T shape of the fence posts: I had to cut a notch to accommodate the posts in each piece of wood. A test fitting of my firepot! This is the general idea of my wooden forge. There is between 8 and 12 inches from the wood to the firepot in any direction. The next step, accomplished many months later, when the snow was long gone: I covered the whole thing with wire mesh, and doused it with dissolved borax in water. Its a fireproofing thing. The back needed to be cut out, and so I did that and added reinforcements so it didn't cave in. I used old flex tubing for the air pipe. It works great! This is the underside. I added cut open steel food cans as deflectors to reflect the heat back from the wood. This added layer of insurance is great, it works like a charm. It is tied with wire to the mesh up top. The forge, finished for now, and with a bright fire licking coal smoke off those smooth black rocks. The fire bricks are movable and temporary. I am not quite done modifying the forge; I would like a steel top rather than the wire mesh, but that will come whenever I can find a filing cabinet or a washing machine shell... Here's the whole smithy, under the sprawling elm tree or whatever the poet wrote. I'd rather have a roof. After the fire was all raked away. The mesh holds the coal well enough! A view of the ash dump, held there by wire. Slightly primitive, but its what I've got. A view of the underside after I raked away the coals. The blower, the thing that makes it hotttttt!!! This is how I have my blower mounted: I have the feet cut off and the tube goes straight int the stump, which has holes drilled to accommodate the piping. There was enough airflow to keep the coals glowing hot for a little while. Amazing! Thus, I completed my forge, in all of its glory! Its not DONE, but its getting there. I just wanted to share this with everyone, contstructive criticism is appreciated, and I wanted to encourage those who don't have welding experience that they can build a workable forge! ~Ridgewayforge
  5. After many months of searching craigslist, asking about this forge or that on IFI, and dreaming constantly, I have finally found a forge. It is now in my posession for only $125. I am the proud new owner of a 12" Champion 400 blower and a Whirlwind firepot! I am having some difficulties though, and after fruitlessly looking through the old posts about fixing 400 blowers and firepots, I turn to you all. The blower makes a rattling sound, but I think it is just the fan blades scraping ever so slightly against the housing. I'm going to try and adjust that. THe big problem with the blower is a classic Newb moment: I can't figure out how to remove the gearbox cover. there are two screws, which I removed, but it doesn't budge. I don't want to break it, so how do I get it open? The firepot clinker-breaker is seized with rust and has WD40 on it right now, to try and loosn it up. the bolts which hold it onto the T-pipe/ash dump are rusted, and I'm going to have to drill them out. They are a solid peice of rust. Last question, how do I attach the ash dump lid? It seems like there should be a bold or a nut to hold it on. Thank you all for looking, ~RF
