Hello I seem to get alot of tougher stoves to fix these days. This is the same stove that needed the FireBox Rust Relief. http://www.hearth.com/talk/threads/englander-pellet-stove-a-little-fire-box-rust-relief-and-smoothing-out-the-ruff-areas.110717/ I am replacing the exhaust blower and housing. The exhaust flange has holes in it! The bolts that hold the blower motor in needless to say, look a little rusty! See pic So I got all the bolts out except one on the bottom side! I tried the dremel but the cutting wheel was not big enough to cut the head off because the side of the dremel hit the side of the stove openning so there was not enough room to move the cutting wheel thru the bolt head! See second pic. So I pulled out the Air Cutter and surprisingly, I was able to manuver the cutting wheel into the stove body and there was room to go across the bolt head. With 200 PSI it went thru the bolt like a knife thru butter! So now my question is: Should I drill the bolt out and put in a larger bolt? Should I just not use that bolt and use all the others?
