Making old nuts, bolts and clips new again

Cool trick with the screen oldmanmopar! I use a piece of wire for nuts and washers (and anything else with a hole in it) coiled into a circle, and start blasting at one end where the two ends are twisted together. With a little practice you can flick your wrist and flip the hardware you just blasted to the other side and move on to the next one. Dedicated -- and wayyyyy beat up :-D -- pairs of needle nose and slip joint pliers live in the blast cabinet to hold bolts.

But I have to add to your comment regarding the use of sand. Aside from becoming embedded into the metal, long term exposure can also kill you. Sand shouldn't be used to blast anything. Silicosis is a nasty animal ...
