Guys just a quick search on e-bay shows plenty of bench vises under $10 and if you have swap meets or flea markets you can buy them for $5 all day long....
I would really suggest picking one up cheap if at all possible, they really make razor work much easier....
That being said, if you have other ways of doing it using even more common tools please post the pics...
I will also post a pic of an actually pinning block which is basically a 3/4 inch thick piece of steel with a 3/32 hole drilled through it... anybody with a drill press will do that for you, if you buy them the bit :)
They usually end up costing more than a vise :shrug: when it's all said and done, and they don't do as much....
