I have decided to invest in a good barrel vise and action wrench set for working on Smith revolvers and have been studying them for some time. I'll likely end up making my own, but I was curious if anyone has attempted, successfully or not, to remove the barrel with the action held in a standard 5" bench vise with the same inserts typically used with the action wrench, while using the once "action wrench", now "barrel wrench" with inserts specific to the barrel to instead rotate the barrel from the action, opposite of the typical action-from-barrel. Obviously, gravity would not be an assistant as the work is being done in a horizontal plane, however the concept seems to be the same. Is there something that I am possibly missing that would cause hazardous conditions for the frame?
