I also process my own deer.What you are considering is quite dangerous,I would avoid that like the plague.Deboning does not take long at all with the right tools,hack saw a couple of sharp longer flexible knives.Backstraps,tenderloins,front shoulders hindquarters,neck,rib meat.Just follow the seams.
As others have said you can refrigerate or freeze a little to get the meat to firm up a bit,or to work on it at your convenience over a couple day period of time.
Having a friend or family member help makes it go super fast if they are experienced.I have a friend who most often helps and I return the favor.
