Musky50 Posted February 12, 2017 Share Posted February 12, 2017 I am new to this to begin with. I built my forge from scavenged metal from scrap yard. The fire pot is 8 x 10 x 4'' deep, constructed from 3/4'' flat plate. I drilled 12 -1/4'' holes in a round 3'' circle. My airgate is a slide in a 3''ID, schedule 40 steel pipe. The blower is a welding gas evacuation blower and is pretty strong, I can easily blow large pieces up and out of the fire pot. The airgate seems to be very sensitive to very small adjustments. I get a good fire initially then it begins to burn hollow and as i push it in from the sides of the pot with a shovel as I have seen done on youtube, the fire cools and then I have to open the airgate and soon it is burning hollow again. I am too new to be able to determine if I have #1- too much air velocity do I need a smaller blower?, #2- poor airgate design, would a round butterfly inside the pipe be better to control airflow?. #3- Do I need to shallow up the fire pot to 3'' and drill more holes to lessen velocity? Thanks in advance for any help you may be able to offer.. Quote Link to comment Share on other sites More sharing options...
