Roastbeef Posted November 16, 2012 Share Posted November 16, 2012 Here are some pictures of my first forge, it was a process of trial and error - so here is the process I went through, and how I ended up with this design. Firstly the burner, using some 1/2 inch galve water pipe that I had lying around, I made my first venturi burner. This worked well but there was not enough heat, so I made another and put the two side by side. The venturi burners were not very efficient in the forge, there was a lot of un-burnt gas coming out of the forge opening - probably because I the burners were not getting enough air. Also the forge was too big, I had made it two bricks high. So I cut it down to just one brick high ( as in the photo's) and did away with the venturi system and connected a forced air supply. WOW this worked GREAT. The forge works really well, the heat is fantastic, I get almost a white heat, also I can "tune" the burners by controlling the air input and gas supply, I can regulate the heat for a "eco" mode or turn it up for max heat. Lighting it is a bit tricky, I normally throw in a lighted rag or tissue and then firstly turn on the gas - this lights up the workshop !, then I slowly introduce the air.

shralp Posted November 16, 2012 Share Posted November 16, 2012 Interesting. Can you forge weld with it? Any problem with the burners being so far into the forge? How do you adjust the air? Quote Link to comment Share on other sites More sharing options...

I guess you can forge weld although I have not tried yet, the burners have a stainless steel bezel welded on the end, they do get really hot and this may be a problem in the future. The air is adjusted by a simple 1/2 inch tap, air is supplied by a blower that I had for a paint spraying system. Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted November 17, 2012 Share Posted November 17, 2012 Good Morning, Move the tips of the burner out of the fire-box. They don't need to be in there. Neil Quote Link to comment Share on other sites More sharing options...
VaughnT Posted November 20, 2012 Share Posted November 20, 2012 Very nice. I like the wood base you built for it. Think about lining the inside of the bricks with ITC100 or Plistix to increase the working temp without increasing the gas used. Quote Link to comment Share on other sites More sharing options...
