r/MetalPolishing

Please any help will do

I recently bought a set of chrome plated Denali stocks but they seem to have some sort of oxidization on them, I’m wondering what the best way to remove whatever it is and polish these rims would be. Any help would be appreciated

I’ve got a set of Centerline Galaxy aluminum wheels that need major sanding and refinishing. There are “dimpled” areas around the lug bolts that need to be sanded and polished. The dimples are 1/2” in diameter and about 1/2” deep. Anybody have any ideas on how I can sand in there with my Dremel? What sanding attachment can I use for my Dremel.

Hello everyone, could anyone please advise me on the best way to remove this surface rust and properly protect the metal from rusting again in the future? I’d really appreciate any recommendations for products or methods that would work well.

Got the new Milwaukee BPS-0 compact polisher/sander to polish my vintage BMX bikes and other odds and ends. Can anyone recommend a nice kit to order for this? Possibly for sanding and more buffing.

so i’ve received an enquiry from a client about this 3d sorta curved edge villa nameplate
and i’m not sure how to get these curved edges right
from wht i could think.. Laser cutting a 6mm Ss304 sheet and then grinding the edges to match how it looks and then finally plating it is all i could think of.

ps- i need it to be as cost efficient as possible

Hi everyone, I would like to ask the polishing experts in this forum for some advice.

I have a project to build a coating pan unit used for coating tablets prior to packaging. The unit's design is quite simple—it resembles a washing machine's cylindrical drum with a front opening, and it rotates slowly at around 2-4 RPM during operation. The unit's shell features a perforated design with 2mm diameter holes. During fabrication, the client requested that the interior be mirror-polished, so we used a polishing compound.

However, after finishing everything and cleaning it using our standard procedure (with alcohol and a clean white cloth), a black residue appeared when we swabbed the surface using a white tablet product.

We have tried cleaning the unit several times:

1. First, using a special penetrant cleaner that is essentially contaminant-free.

2. Next, using various types of food-grade detergent mixed with hot water.None of these worked. We even tried performing a passivation process twice (before and after the unit was installed), hoping that the degreasing stage during passivation would lift the dirt off the unit.

Yet, after every cleaning attempt, wiping it with a clean white cloth shows no visible dirt, but swabbing it with a white tablet still leaves black smudges. We strongly suspect that the laser-cut perforated holes are trapping leftover polishing compound (Langsol) that has now encrusted and hardened, making it incredibly difficult to remove.

Does anyone have any suggestions on how to get this unit completely clean? We are completely out of ideas. Do we really need to poke and clean the holes one by one? Also, are there any specific cleaners or methods we can use to effectively clean this unit?

Is machine work involve to get this shine?

I’m currently in the process of refinishing some rims. They’re forged aluminum and I’ve sanded the bead rings down to bare aluminum as there was some pretty gnarly oxidation under the clear coat. Started at 320 grit to get it down to bare metal, then hit with 400, and 600 grit. Will hit it with 800 next and likely stop there.

Been doing some reading on how to best care for and protect bare aluminum and have seen everything recommended from White Diamond and renegade down to wd40 and PAM cooking spray. I currently have mothers mag and aluminum I was planning to use, but are there other products I should use before or after Mothers? Should I use something else all together? Ideally looking for something that cleans and protects as these wheels will see snow and salt. Thanks!

Was recommended to post my work on here. Before and after some charcoal bluing and if you want to see more drop me a follow on instagram.

I'm trying to restore a vintage toolbox. The emblem/badge has chrome raised lettering. The chrome has chipped off/pitted in many areas. Any suggestions on what to do about this chrome? I stripped the black paint off of the background as I plan to recoat that with black model paint enamel.
