So completed my alterations to the burners on the forge. She welds!! Props to the Frosty burners. I was able to salvage the brackets to hold my manifold, and it made tuning the burners easy without having to cut the welding tips. Thanks again for all the help guys.

Well after pricing out materials I have decided to repurpose and build the tried and true Frosty burners following the plans on this wonderful sight. I do also want to say how great this community is. I mean the amount if knowledge and advice that is given is amazing. This really is a tight community. I mean where else can you start a conversation about burners, get help on them and then move into a conversation about roundabouts, which In my area I am in full support. They really have cut the number of severe/fatal accidents on my areas roads.

I got the basic design from on line. I should of asked more questions before I built the burners. Thank you for all the advice. I'll be hitting up the plumbing store to get a couple new bell reducers and nipples to shorten my mixing tubes. I have already closed up the holders and that helped a lot already. I'll put the .03 mig tips back in as well Thanks again all.

Sorry its been awhile since I was on. Life has been not very friendly to my honby. I made a propane forge for forge welding but I can't get it hot enough. I've been tweaking and adjusting my burners and still nothing. The forge chamber size is 5x5.5x11, I have a double burner set up. 9" long pipe with 0.04 might tips. Burner flame looks good, I have the orange dragons breath out the front. Even blocked off I can't get a piece of 1/4" to welding temp. Any help would be appreciated. oh forge is well insulated with 2" of kaowool. Sealed castolight , and coated with its 100ht Sorry forgot to say the burner is 9" 3/4 pipe down to 3/4:1 reducer with threads removed on the 1" side.

I have a very basic air gate just off of the ash dump. I just need to learn how to use it efficiently. Covid has really messed up my ability to go to my local smith's shop to learn fire management and what a good fire looks like, and how to tend it efficiently. But that's for a different forum lol.

As a Gass fitter in ontario, any flue that isn't 636 venting for a furnace, that goes through a wall or attic, or any space that will have temp variances needs to be double walled and be so many inches from combustibles. This clearance can be reduced if using certain rated insulation. Please don't quote me as I don't have my code book and charts on me. Basically you should have double wall pipe, that is rated for intended use.

Spiral duct is galvanized, it all depends on the heat you have going through it, for safety reasons stove pipe would be best

Get the stuff with a seem and put 6" together. Or a 6 and a 4 if you have to have 10. That's what I did.

Thank you Thomas. Your right, I need to learn how to used what I have to get the desired results. Now to figure this out. Thank you again.

Sorry really really messed my measurements up. All pipe is 3" it's about 1 1/2 foot run from each fan. Yes I know it's very very rough.

This is my set up. It heats steel fine, but it can blow the coal up easily. I'm attempting to forge weld and I'm afraid I'm using an oxidizing fire that burns my steel before its at true welding temp.

So I'm looking at getting a new blower for my coal bottom blast forge. Right now I'm using two old bathroom fans that give me about 140 cfm. I put a manonimeter on and found I have 0" w.c. even with the gate fully open. I know I should have pressure and not cfm. I have another fan that might up the pressure, but it would add another 70 cfm. My other option is I just buying a sunlar 110v 250w blower. I'm just looking for some feed back. I have tried some experiments with blow up motors to no avail and a air mattress pump after seeing that Lucky swears by them, but still not getting over 1" w.c. I need to keep my costs down as this is a hobby/ potential way to make a bit of money. Any advice would be appreciated. Just took some measurements if it would help with advice. My tuyere is 3" by 8" long.

I'm sorry for coming across this thread so late, my prayers are with you and your family. Please be safe and do what you need to do to be with your family in this difficult time.

No worries Welshj, this is how we learn and share , I'm always open to conversations being expanded on. Hey Bob, thanks for the info, When I get some time I'm going to check it out. I've seen some of the stuff Jason has done and it's cool, Kinda wish he would do some more judging on forged in fire.
