It ran from 9AM till 3:30PM, when the storm hit.I used just under one tank.The biggest mistake makers make is running the forge at full throttle. You bring it up to the heat desired,and back the pressure off until it maintains the heat needed.You don't need a 2300 degree chamber to forge out 10XX blades.The lowboy is nearly whisper quiet at forging temps.The forge chamber should be at a temperature where the steel won't burn up if left in a bit too long(this is the cause of many poor blades).Once properly adjusted you can work on two pieces at a time,with one in the forge while you are hammering on the other.Put the one back in and take out the red hot one.
Once it has been running for a long time it will take a fully heated forge a LONG time to cool.The rain poured on the forge for one hour before it let up enough to pack the gear.The bottom was still too hot to move bare handed.
As they get down to 1/4 full,propane tanks may freeze up due to the cooling of the propane under the constant boil off.If it does ,gently shake the tank a bit ( to break up the frozen propane ice) and that will give you some extra pressure.If it gets really frozen up,change tanks and let that one warm back up.A 100 pound tank at the permanent forge can make this less of a problem.
