Biggest challenge with the old rifles is avoiding “idiot marks”; screwdriver scratches, hammer dings, flattened corners from dropping the rifle because you don’t have two sets of hands. So there are a few tools you need to become a successful Mauser owner.
I bought everything listed below at princess auto except for the bench vice, that came from Home Depot. Right at $100 for everything. Delrin scraps can be had at some machine shops for a six pack or a skidoo track slider will work
Ball mount bench vice (let’s you turn the rifle in more ways than a gun station will. The dremmel one works really good)
Brass hammer (NEVER ON THE EDGES)
Delrin plastic blocks (for placing against barrel band edges and hitting with brass hammer)
An assortment of brass punches (trigger pins)
A set of plastic jaw clamps (compress band spring while striking band with delrin block and brass hammer)
Hollow ground flat head screw drivers (new tapered profile screwdrivers are not meant for straight cut old slotted screws. Get a profile that is the right width and won’t cam out as you turn.)
Also, I put my guns in the oven. Lowest setting is under 100f and the cosmo drools right off. Yes it stinks but it works. You get a clean rifle and food cooked on the bbq tastes better anyway!
