Rainbows Posted January 6, 2015 Share Posted January 6, 2015 I have been seeing a few of these flame fast chip forges on ebay, sometimes for very low prices. Has anyone used these? Do they work well? Quote Link to comment Share on other sites More sharing options...

njanvilman Posted January 6, 2015 Share Posted January 6, 2015 And if someone could add, how do they work? Quote Link to comment Share on other sites More sharing options...
Rainbows Posted January 6, 2015 Author Share Posted January 6, 2015 There is a gas flame at the bottom to heat stuff up and I think you put the work on it them cover it in the ceramic chips to keep the heat in or something like that.

Charles R. Stevens Posted January 6, 2015 Share Posted January 6, 2015 It actually heats the chips, the chips heat the steel. Acording to the manufacuer and the former post. Quote Link to comment Share on other sites More sharing options...
njanvilman Posted January 7, 2015 Share Posted January 7, 2015 Now I understand how they work, but now I want to know along with the OP, do they work well? Do they get steel hot enough to weld? How is the heat concentrated? How long of a heat on a bar can you get? Fuel consumption? Anyone have any experience with them? Quote Link to comment Share on other sites More sharing options...
David Edgar Posted January 7, 2015 Share Posted January 7, 2015 The Flamefast chip forge is popular in schools in UK. It costs about £3000+ new. Depending on the gas jet (which is easily changed) for either Propane or Natural gas,max heat is lower on Nat. gas models as the pressure is lower. Propane runs hotter and will melt mild steel but produces a lot of scale as it has an air blower. The torch is very convenient for localised heat or lighting a coke forge. The gas and air mixture is pumped into a plenum chamber beneath the burner which is similar to the ribbon burners I have seen pictured, a ceramic disc with lots of small drilled holes about 1/8" size. This disc is about 6" diameter. It needs about 12kg. of ceramic chips which costs about £60 from Flamefast. Length of heat is same as coke/coal forge, as is the footprint on shop floor. Gas consumption is fairly high,but no doubt could be adjusted down. It is easy to use for the small shop but is no longer popular in the larger pro shop. Hope this helps.

njanvilman Posted January 7, 2015 Share Posted January 7, 2015 David Thanks you for the complete explanation. It all make sense now. I think I will stick to my coal forge for now. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 7, 2015 Share Posted January 7, 2015 Also the chips degrade with use and have to be replaced Quote Link to comment Share on other sites More sharing options...
Rainbows Posted January 7, 2015 Author Share Posted January 7, 2015 £3000? Those schools have too much money to burn. I see one used for £200 and I have seen them go for less previously. Quote Link to comment Share on other sites More sharing options...
