I think I am going to try and find someone local that has one of these, I read it makes a pretty rough edge though. Possibly might even try to get a flame inside of it from a good distance away http://www.globalindustrial.com/p/mater ... r-standard
I was also thinking about just cutting the entire barrel in half with some tin snips first, then using a sawzall for the top. I am trying to leave the rim of the barrel behind.
Also I need some advice from anyone with experience, I was going to make a large wooden mallet for smoothing and sinking the last 1-2cm and when I am preparing the frame around the notes, but I ran in to this when I was picking up my sledge:http://www.harborfreight.com/2-1-2-half ... 66206.html
Would that suffice for the purpose or would a wooden mallet have any advantages?
