For those who haven’t seen it, there’s a seen in Evil Dead II where the hero uses a chainsaw (attached where his right hand used to be) to cut off most of the barrel of the shotgun that he is holding in his left hand. I’m just wondering what would happen if that were actually tried. It sounds like the concensus is a ruined chainsaw blade, the shotgun knocked out of your hand, and maybe the bar of the chainsaw imbedded in your head.
FTR, I like my shotgun just how it is and have no plans to saw it off.
As for the fire dept saw. I’ve used what my brother calls a “maniac saw” which has an engine a case very similar to a chainsaw, but instead of a chain, it has a large ( ~ 2’ diameter) abrasive disc. It works well to cut through concrete, I don’t think much would slow it down.
