Best methods to revive nuts/bolt?

[CADplans]

I have three methods of part revival that will work for nuts and bolts.

BIG;





SMALL;





SLOW;



Big and Small use Black Magic grit, Slow uses Washing Soda, and a GT battery with a charger.

They both spin, the "Small" was an epoxy mixer, works great!!



Maybe you could make one out of an old Cub Cadet transaxle!!

Matt G has a good write up on his site about replating bolts.

I clean the hardware with acetone then put it in a citric acid solution (1 Cup to a gallon of water).

For a container I picked up one of those cheap plastic storage totes at an after charismas clearance sale. let sit 24 hours take them out then a couple of seconds with a wire wheel. It wont fix any pits but it'll shine like new. I've done an entire Brinly plow, an 1890 Oliver plow, & all of the rusty parts on my 127 this way.

Citric acid is the stuff in Catsup & Coke that cleans rust. Any way you can buy in on amazon or eBay (its the same stuff that goes into your wife's bath bombs) I like to dissolve it in hot water (gallon or so) and add the rest of the water. it non GMO, gluten free and most importantly non toxic. it doesn't off-gas like electrolysis and doesn't require special handling or special disposal.

Plain old white vinegar for rust.
Mineral spirits for oil/grease.
Ya gotta get the grease & crap off first before the vinegar will touch the rust.
Then a trip to the wire wheel on the bench grinder.
Vinegar turns the rust to mush and the wire wheel takes it off.
Then toss 'em into a can/jar with a little diesel/solvent/mineral spirits whatever to keep 'em clean tiil Ya need em. I use peanut butter or mayonaize jars. Shake 'em up once in a while.

THat's not counting the money you'll have to spend to replace the half of them that are launched into low earth orbit never to be seen again until you move.
