Laynne Posted March 18, 2019 Share Posted March 18, 2019 Has anyone experimented with multiple tuyeres in a JABOD using charcoal? I have come by some shafting in the 2-3" range that I would like to work in the forge. I have read the JABOD threads, just wondering if anyone has tried it. Any do's or don'ts.

Irondragon Forge ClayWorks Posted March 19, 2019 Share Posted March 19, 2019 You probably need to expand on the "multiple tuyeres" do you mean one pipe with many holes in a bottom blast configuration or more than one pipe in a side blast.

Laynne Posted March 19, 2019 Author Share Posted March 19, 2019 I was thinking 3 pipes in a side blast configuration. Roughly 12" long by 4" wide. One pipe coming in from each end and one at 6". I would block the ones on the ends with fire brick when not in use. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted March 19, 2019 Share Posted March 19, 2019 Must say, I've never seen that configuration but an interesting idea none the least, would make for a big fire with all three running. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted March 19, 2019 Share Posted March 19, 2019 That is pretty classic for sword heat treating forges. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 19, 2019 Share Posted March 19, 2019 When I needed a long forge for box folding some 3/8" plate; I dug a trench in the yard and put a pipe down the length with a lot of holes and blew it with a shop vac output. For an intermediate length forge I took an shallow old rectangular dry sink and ran a pipe with a lot of holes down the middle and mounded up creek sediments to make a V shaped valley (using coal, U shaped valley using charcoal). I had drilled a ring of holes in one end and punched it out for the pipe to exit and made a ramrod that would just fit the pipe allowing me to adjust the length of the fire. Again powered air.

Charles R. Stevens Posted March 19, 2019 Share Posted March 19, 2019 If you want the tuyere to live longer, come in from the side Quote Link to comment Share on other sites More sharing options...
Laynne Posted March 19, 2019 Author Share Posted March 19, 2019 More food for thought. Thanks for the input. I've been thinking maybe there's a simpler route. I could go from the 3/4" tuyere to 1" with a ball or gate valve to control air flow. Less time tearing down for plumbing, fire bowl stays the same size.

Charles R. Stevens Posted March 19, 2019 Share Posted March 19, 2019 99% or more you just need one tuyere, for those get times you need more a temp set up sets you in business. Quote Link to comment Share on other sites More sharing options...
Laynne Posted March 19, 2019 Author Share Posted March 19, 2019 The temporary set up makes more sense with the one off/occasional use. Thomas, I now remember you speaking of the trench dug in the yard. When I've done it one way or the other I will report back. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted March 20, 2019 Share Posted March 20, 2019 I wish I had a picture of Steve’s set up. It is a bottom blast but his long fire adapter is great Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted March 20, 2019 Share Posted March 20, 2019 I have a 1 inch diameter pipe for a 30 inch long trough tuyere, I have 3/16 inch holes along it to allow air to exit evenly one end is capped. The other end has a 90 degree fitting with a flare that matches up with my normal tuyere opening of the bottom blast. Since my forge top is 30 inch by 60 inch 3/8 thick diamond plate, it not only makes a good work table, it also doubles as deck for a trough forge when needed to heat long section for heat treating or large bends Quote Link to comment Share on other sites More sharing options...

Laynne Posted March 20, 2019 Author Share Posted March 20, 2019 Thanks Steve, that gives me a good mental picture of how you do it. Quote Link to comment Share on other sites More sharing options...
