First off, I am new and I am located in Livermore California so if any of you are near by I would love to hear from you.
Now the project, I am going to be putting a brake drum forge together in the next day or so. I have a piece of 3/16" steel plate 3'X4' for the deck. The edge will be 2x2x 3/16 angle. The drum is off an F250 and the O.D. of the lip is 14". I plan to burn a 13" D. hole in the deck. Then use the cut out to make an 8" disk that will be bolted to the bottom of the fire fire pot using the existing drum bolt holes. I will be using 2" square tube for the tuyere and ash dump (cuz I have a bunch of it). The blower is going to be the discharge side of a shop vac until the noise drives me crazy. I plan to make a side draft chimney for it at a later date.
So, with the above in mind, where would you locate the center of the drum cut out and why?
Thanks
