After spending my 14 days at work I arrived home to a small amount of snow on the ground, which was a bit of a drag since October had just arrived a few days ago. That's a month or so early. Plus it was cold (3 deg. F) which is an even bigger problem as I want to try to start making some ingots while I am home.
I have been thinking of a way to cut down on the airflow I get from using my Shop-Vac as an air supply to my furnace. Since I can't easily reduce the output at the Shop-Vac, the flow needs to be reduced at some point along the connection to the furnace. So what I have come up with is cutting an opening in the supply pipe that slips into the tuyere, as well as fabricating a deflection valve to divert a portion of the air flow up and out of the opening. Since I am trying to use only some basic tools, cutting the opening will take a bit of time. I will put a picture of the modification out when I get the opening cut and the deflection valve fit. Then it will be time to try melting some of my scar pile and making some ingots! If the weather cooperates.
