Thanks everyone for the quick replies.
One big reason I want to get away from electric is because currently I have to run an extension cord from my kitchen and across the backyard to the place I can forge safely, and we have no outside electrical sockets or power in the garage. So that becomes a problem, especially with kids and pets running around.
As for the forge build; that’s what I got to work with, lol. I’m looking into getting a welder in the next few months so I can have some more versatility when it comes to modifying stuff but for now it is what it is.
I’ll start looking into the blower’s CFM though and see what I can figure out. Thanks everyone. =)
