| I have halligan bar that is chrome plated and I want to get rid of the plating. How can I do this without a sandblaster? I guess I can acid bath it, but is there another route? |

Muriatic acid from lowes or home Depot. It will strip the chrome but will leave the nickel plate that is
underneath .You can paint or powder coat over nickel as long as you give it a good scuff. Muriatic will also eat off any rust that you have on the part. Let it soak for about 45 minutes if you go this rout. There is no other wat to strip chrome than this meathod unless you sandblast . ( worked at a chrome shop years ago) |

What is the base material? Steel? Decorative chrome? Usually pre-plated with copper. This can be removed from steel using aqua ammonia. Caswell Plating should have more information. Not true. Tubing is one that they do not copper plate. There will be only nickel and chrome on that part I guarantee it. The reason you do not copper plate tubing is that it tries to adhere to the low current density areas inside the tubing. When you pull it out of the tank it rinses all the loose plating out into your plating bath. It will shut the tank down and costs a shit ton to get it all filtered out and running right again. |

The Caswell Plating website has a user forum where these sorts of things are discussed. I had a pistol that had been nickel/chrome plated and I wanted it restored (it was a WWII bringback that a family member plated in the 1960's). I did a reverse plating process to get rid of the chrome, and Caswell's nickel remover to get it to bare steel. I did have a couple liters of hexavalent chromium solution that I had to reduce with ferrous sulphate to trivalent chromium before the hazardous waste place would take it off my hands.
I would take it to a plating shop and have them do it. All the plating shops around here wouldn't help me because "it's a gun!", that's why I had to do it myself. |

Not a bad idea but he will be hit with a minimum charge anywhere he goes .From $95.00 to $150.00 . Also more than likely they will only strip the chrome and leave the nickel. Most plating shops reverse nickel strip tears the shit out of the base metal before it all ends up coming off. |

The best way to have ANY chrome removed is to have it removed at a plating shop....It's basically a reverse of the plating process.
Those people (excluding the poster above me)  know the correct electro-chemical process by which to do such things.
If you just want to paint it, sand-blast it. |

Probably a browser issue (I'll take a shot in the dark and say the issue comes from a phone browser) I don't think anyone is doing that on purpose, so cool your jets both of youse

Not true. I am a Metallurgist. One of my specialty fields is electroplating, including chromium. I've wrung enough chromic acid out of my coveralls in a day to send a OSHA-type to the fainting couch. The classic method of chromium removal is to apply reverse (cathodic) current in a caustic solution (usually sodium hydroxide). Takes awhile to do it, of course, but should leave the nickel intact as well. Removing nickel is actually VERY easy if you have access to chrome plating solutions - just put it in the chrome solution and apply reverse (cathodic) current. The nickel will fly off of the part! Also, just because there is chrome on a part DOES NOT MEAN that there is necessarily nickel and/or copper underneath of it. Decorative chrome is a multi-layered coating (usually with all 3 - Cu, Ni, Cr). But engineering (or Hard) chrome is often just chrome and nothing else. If plating on a stainless steel, then odds are that a woods nickel strike will be applied first to promote adhesion, but even this will be MUCH THINNER than the nickel layer used in decorative chrome. I see parts EVERY DAY with hard chrome that have nothing underneath except the steel. With a good plating shop, and a metallurgist who knows his trade, it is very doable. |
