DaveP, Kywoodwrkr:
Granted, Brownell's tools are very nice indeed, but they are sorta PRICEY!!
As a matter of fact, some two weeks ago, I found barrel vises on sale on EBay. The guy apparently made them in his machine shop, and they looked good, at a good price! Do a search using keywords: "barrel vise"
Check out this web site for instructions on making your own action wrench: Turkmauserman.com He's an amatuer gunsmith with some really neat ideas on mauser sporterizing tools.
If you have acceess to a machine shop or a machinist friend, making your own barrel vise is pretty easy...a one-evening activity. You mill mild steel slab stock 1 3/8" to 1 1/2" thick into rectangles, drill and counterbore clamping and mounting holes for 1/2" bolts, and bore the barrel shank cavity. Turn aluminum insert collars to fit your barrel shanks, and that's it!
I'd be careful if using a universal "inverted vee" action wrench on the M1/M14 receivers. A specially-shaped one that fits exactly is safer. You don't wanna scratch or crack an action, do you?
