Todd Honhart Posted February 19, 2019 Share Posted February 19, 2019 You definitely have a lot of sparks, my manual air pump didn't throw any sparks. However I certainly had too large of pieces of charcoal on the fire also. You are right in the same boat as me so far, just trying to see what you can do.

cmoreland Posted February 26, 2019 Share Posted February 26, 2019 Hey Charles can I ask where you got the air pump? I've looked all over town for one but all I can find are the skinny bike ones. EDIT: Found it on Amazon - can I revise my question and ask how you are liking it still? Would it be a lot of work with lump charcoal? I don't have access to coal/coke in my area.

Todd Honhart Posted February 26, 2019 Share Posted February 26, 2019 They are on sale in the sports departments at Walmart for $8.97 Quote Link to comment Share on other sites More sharing options...
Frosty Posted February 26, 2019 Share Posted February 26, 2019 I just did a quick search using "Hand pump mattress inflater" for terms a n d . . .What Todd just said while I was typing. I've been picking up 12v blower, mattress inflaters at yard, garage, etc. sales for next to nothing for years. Recently if Deb's along and I show interest in one she says something like, "Don't you have enough of those?" and I have the seller toss it in free if I buy something else. Here asking is usually $0.50 - $1. Walmart gets around $10 in season and a couple bucks in closeout season. You can run one of these all day on a motorcycle battery ad they put out WAY too much air. Not saying you should but it's an option. Options are good you know. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted February 26, 2019 Share Posted February 26, 2019 They work well with lump charcoal, which takes a lot less air as coal or coke. I've seen them in most stores that carry sporting goods and camping supplies. Quote Link to comment Share on other sites More sharing options...

cmoreland Posted February 27, 2019 Share Posted February 27, 2019 I'd better steel myself for such an occasion then. I hardy ever see those anymore. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted February 27, 2019 Author Share Posted February 27, 2019 I have a hard time finding the larger one at Wally World, tho you can order them. Sporting goods stores that deal in camping gear tend to have them. For small coal forges they work just fine. It’s hard to get to melt it temps so they are a bit slower to heat but with a good arm and patience welding heat is doable. It’s not optimal for welding heats and 1” stock but for 1/2” square or smaller it is just fine. A pump with twice the valum would be idea if you are trying to get to a 6” welding heat in 1” stock using charcoal. Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted February 28, 2019 Share Posted February 28, 2019 Basically a variation on an asian box bellows. I like the back and forth motion of the box bellows to the up and down of the one shown. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted February 28, 2019 Author Share Posted February 28, 2019 I mount them sideways. About 22.5 deg. Up from horizontal. Thus a pumping motion like sawing a board Quote Link to comment Share on other sites More sharing options...
Todd Honhart Posted March 1, 2019 Share Posted March 1, 2019 I mounted mine horizontal under the box with the handle protruding towards my legs. I made the box tall so putting it under the front is reachable, but even after only doing it for a few minutes I can see how having it a bit higher would make it easier.

Charles R. Stevens Posted March 2, 2019 Author Share Posted March 2, 2019 Yea, that would kind of suck. The first one was about 45 with the top just above the hearth. This is much more confortable This is much more confortable Quote Link to comment Share on other sites More sharing options...
Todd Honhart Posted March 2, 2019 Share Posted March 2, 2019 Undoubtedly more comfortable than my underneath set up. I made the box rather large and didn't want to add any width, so it was easy to store and move. I think I may make a removable mount that I can quickly attach/detach.

pnut Posted March 14, 2019 Share Posted March 14, 2019 Charles R. Stevens, I've bought a double action pump similar to yours to use with charcoal in a four inch wide by five inches deep trench type jabod. The pump I bought is a 14.5 inch double quick III S . I hope it puts out enough air. I work stock usually no larger than .75in. three eighths mostly. My tuyere is 1inch schedule forty pipe. I nearly forgot to mention that. I was wondering if the 21 inch pump is more than adequate. Does it make more air than you need without having to pump like a madman. If so I think the smaller one I purchased should suffice. If not I may need to order the 21inch pump as my local Walmart doesn't stock it I will let everyone know how the smaller pump works out. It's going to be a while though. I'm out of stock fuel and time. So when I get all three I'll post an update. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted March 14, 2019 Author Share Posted March 14, 2019 You might try a 3/4” schedual 40 pipe for your tuyer, if it dosnt seem to work well with the 1”. Schedual 80 pipe is dang near spot on for the advertised ID but as schedual 40 shares the same OD its ID is bigger, thus 3/4” schedual 40 is close to 7/8” ID wile 1” is close to 1 1/4. I would think your tue would work but I know 3/4 works plus the air hose fits right in with just a rap or two of electrical tape. Quote Link to comment Share on other sites More sharing options...
pnut Posted March 14, 2019 Share Posted March 14, 2019 Charles I have an electric mattress inflator I just don't like the noise or having to run a fifty foot extension cord to it. Otherwise it's working great. I would rather not have all the racket the electric pump makes. Thanks though if it doesn't want to heat up I'll switch to a smaller tue. Hopefully I won't have to. Oh yeah thanks for posting such a simple forge. At first I Naturally wanted to complicate things unnecessarily. The good idea fairy likes to pay me a visit once in a while. Good ideas are the worst things that can happen sometime Thanks. Pnut (Mike) Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted March 14, 2019 Author Share Posted March 14, 2019 I don’t care for the noise either. You can put it in a box with the air holes facing away form you. The electric is just about a requirement for using coal as you would need two of the hand pumps to push the required air. the JABOD forge was the result of my experiments with side blast, and as a counter to the brake drum forge. The Mk II is intended as a portable demo forge to show folks how inexpensive and simple blacksmithing can be Quote Link to comment Share on other sites More sharing options...
pnut Posted March 14, 2019 Share Posted March 14, 2019 Charles, you were successful. It did just that. Showed me how inexpensive and simple building a forge can be. Once again it was a great help and I'm sure there's many others out there who haved benefitted from your posts also. Pnut (Mike) Quote Link to comment Share on other sites More sharing options...

pnut Posted November 12, 2019 Share Posted November 12, 2019 Any chance this could be pinned as a sticky? As of now I had to go back four pages to find it. It seems to be getting buried deeper and deeper into the pages of this section. Thanks Pnut Quote Link to comment Share on other sites More sharing options...
Glenn Posted November 12, 2019 Share Posted November 12, 2019 Pnut or others: Please locate the instructional threads on JABOD, all topics and copy and post the URLs (or send them to me) so they can be grouped together. This will be of more benefit than the individual threads. Quote Link to comment Share on other sites More sharing options...
