Barrel replacement illustrated

How much torque do you put on the bolts that hold the wrench onto the receiver? Is it torqued down? Or just snug enough that the wrench will not shift on the receiver?

My receiver wrench has been modified slightly to hold the brass shim stock between the receiver and the wrench. It is not tight...You don't want it tight...

This is surely not the only way to swap barrels, and not even the best way; it is just my way to do it...And my techniques evolve constantly...
