VObration tumbilng steel bolts?
I have a quantity of larger size steel bolts and nuts (5/8 and up). It
is a nice pile from which I get just what I need for whatever I am doing. Except that they are dirty and rusty. My question is, can I tumble them with ceramic media, or is there a possibiilty that it will ruin threads? Any ideas? i |

Any ideas? i Oh..btw..if you find a vibratory deburring machine..and the inside is worn out..simply take it to a shop and have it sprayed with Rino Liner or any other good bed liner. Works freaking great and is very cheap for something that small. Seems to outlast the standard replaceable liner too.

VObration tumbilng steel bolts?
So after a few hours, the pennies were shiny, but not perfect new
looking. Still a bit of patina on them. I decided to try Brasso, added about 2 tbsp of it and will tumble for one more hour. The point, of course, is not because I need shiny pennies, but just to experiment. i |

The alkalai will cut grease and the electrolytic action will attack rust but not good steel. |

Per pound price isn't too bad, and they degrease them and derust them before coating. -- Steve Walker (remove wallet to reply) |

Agree with John. It would be much better to just clean each one prior to use rather than risk damaging the whole lot. The electrolytic derusting process works a treat. http://www.stovebolt.com/techtips/ru..._derusting.htm --Winston |

I recently was given a pair of power supplies from a Moog milling machine, Nice self contained high amperage, low voltage (5vt DC @ 22 and 50 amps) boxes that will be turned into derusters in the next couple weeks.
