billgiles2 Posted November 14, 2013 Share Posted November 14, 2013 I am planning on using a 2" blanket in a gas forge I am making out of a 5 gallon propane tank. Most of the suggestions say that I should position the torch so that the end is about 1" from the end of the blanket. I just read a blog on another website that said that the flame should not tough the blanket or it will burn it. Which is correct? Also, i was wondering if Plistix 900 is also appropriate to use as a stiffner for the blanket? Thank you. Quote Link to comment Share on other sites More sharing options...
Frozenforge Posted November 14, 2013 Share Posted November 14, 2013 Look up Ron Reil for good information. You might consider 3" if insulation to get the internal volume down so a single burner can be used. Typically a 3/4" burner can heat around 350 cu inch.

Dodge Posted November 14, 2013 Share Posted November 14, 2013 My 2¢: If you coat your blanket (and it should be coated to prevent particles from being breathed) you can actually form the flare into the refractory itself. Its the way I have done it with good results. I use refractory mortar over my blanket and mold a tapered flare in the hole where the flareless burner pipe enters. Bada bing, no more burned out flares :) As for the metal flare, it should just meet the inside of the forge but not protrude into it. even a 1/4" recessed is good Quote Link to comment Share on other sites More sharing options...
