I used it a little after I got it made and it works but I think I need a little more powerful fan and I got to find some coal. I was gonna cut the brake drum with a plasma cutter but it wasn't working right so I scored it real deep with a big angle grinder and hit it with a heavy hammer til it broke out and then cleaned it up. I have a tee in the air supply with a nipple screwed in with a cap on it for a clean out and the screen you can see in the picture is just loose in there so I can lift it out as well.
