Guys,
I agree that the machine could be repaired and if someone needs it and is inclined to do so then, have at it.
My concern is that whoever blasted a cutting torch across it really needs to examine their overall aptitude -very carefully. As beginners, we all make mistakes -it is totally expected; however, I contend that anyone who knows how to lite-up an acetylene torch should know enough to not be so careless. That was an act of either total disconcern for a piece of equipment or, it was an act of total unawareness of what happens with a cutting torch.
If it was due to total unawareness, that person really needs to think about never lighting a torch ever again. If a sane, adult person, living in the modern age knowingly picks up a loaded firearm and the first thing they do is look straight down the barrel -then that's a good sign that person should never handle a firearm as it's a sign they do not possess even the minimal inherent safety reflexes to exist in that field. Some people are indeed accident prone -and they regularly get dismissed from their jobs in the industrial trades.
