    Metal polish


    I'm looking for a metal polish that doesn't have a wax protectant in it.

    Well, I'm not using it to protect. I'm looking to try it out on a useless action and barrel, both of which are destroyed thanks to a 308 in a 270. Yes, it works. Headspaces on the bullet. Wanting to see if it'd work as well as the hours I currently spend on polishing barrels and actions.

    What's wrong with wax?

    I use Flitz for a lot of things.

    How about toothpaste?

    The wax would inhibit the hot bluing process, or so I'm told by the company. I've got pounds of different polishing compounds for chrome moly, but all of them have wax in them.

    I bet a traditional type of toothpaste would work.

    Wonder how well that'd work on a polishing disc on a bench grinder? I'll try it out on rag and see.

    I think most of them have was in. I agree it does give a weird feel to the metal after.

    While I was trying to find info on a clay based product I found this very interesting article on polishing.
    https://www.ganoksin.com/article/buf...ing-materials/




    This is the way to polish a barrel though. A 320 belt or finer will do the trick.

    Robin, all of my polishing that I've done has been to 2000 grit. Of the few rifles and handguns I have that are blued, they are mirror finishes. That's what I'm trying to fix. I'm tired of working on a personal project for months on end to get the desired result. I get enough gunsmith work the way it is.

    So your doing better than 2 rms. Sorry I was not on the same page with what you were after. I worked at a place that had a superfinisher that was a vibrating / oscilating air operated device with an interchangable felt type pad that used a couple of levels of diamond compound but I do not remember what the vehicle was. Doesnt seem like it was an oil base or parafin product.

    It was very similar to this. It did not register on the profilometer.




    There may be something that fits your Aplication

    Please explain this. Seems a bit over the top for the few times I'd use it. In 5 years I've had this shop, we've had 1 guy ask for mirror finishing, and he paid for it to the tune of 75/hr. I'm looking for something that'd work well for the 4 or 5 rifles/pistols i do a year. If I have to keep doing it the old fashioned way, I will. Just a lot of time involved doing a 30" barrel.

    I don't know how it would work on irregular surfaces and I can promise you it is out of your price range for just a few jobs a year. I am curious how electro polishing would work on a surface that already has a very fine finish. Outside of buying the abrassives and mixing it with a binder that is non parafin based or is fat free/greaseless I got nothing Trenton, Good luck bud.

    Edit: For the barrel you might be surprised at what that Crankshaft polishing machine is capable of.

    Crankshaft superfinishing that I saw when I was in the auto industry was a burnishing process. No abrasive. High pressure on some sort of hard metal pad. To be honest, I didn't pay a lot of attention to how they did it. That wasn't my pigeon. I'm not so sure the RMS was what they were after so much as compacting the surface for wear and crack resistance. Like shot peening.
