Could someone tumble some small stuff for me?

[guiri]

I have some small parts made out of stainless that I need tumbled to finish them off but the people that made them couldn't get them to come out shiny after tumbling them.

Would/could anyone do it and if so, how much would you charge me?

It's about 70 stainless steel "hooks" and are about 3x1"

Pic attached.

Thanks

Probably need to be polished tumbling will not make them shiney depending on the finish of the finished good.

Well damn

Hard to just polish with that bend...

Thanks

Location? Throwing them in a tumbler won’t hurt to try.

I'm in NC but it won't cost me much to ship the stuff. A few pounds only.

How much would you charge me?

Thanks

Didn't these used to be flash chromed back in the day?
I remember having display cards of these hanging near the cash register right next to the Bungee Nuts.

[guiri]

I doubt it 'cause it's my product but perhaps something similar and no, these are not chromed.

Those need a buffer wheel and compounds


Do they need to be mirror polished or how reflective / smooth

Once polished, individually wrapped to prevent scratching

Probably easier to have them locally hard chrome plated

[hermosabeach]

What are they for and what is specified in any contract?

Both sides polished?

Polished in the fold?

You would really need to do a sample to see how hard the steel is, what compound is needed or do we need to run it through 2-3 different compounds?

2 is easier

Light compound left wheel and heavy compound on the other - no wheel changes

With that standard of precision, difficulties may arise.

THey're going to redo them and no, nothing was mentioned about them being finished better than they were but the owner didn't like them either so he's redoing them., However, he lets me keep the old ones and I wanted to get them tumbled/deburred and all that.

They tumbled them for me but it took away the shine so just wanted to see if anyone can do it for me without spending a fortune.

I just found a tumbling discussion here so I decided to just post here and it turns out I was already a member so...

As for where I am, wouldn't cost me much to ship'em.

I could buy a cheap tumbler for this and it would still be worth it 'cause I got'em for free, but I really have NO use for the tumbler after this and again, I have no idea what to use to keep them shiny IF that's even possible.Also, I don't want to complicate my life trying to figure stuff out if I can just have someone do them. You know, someone at home that's not gonna charge me business fees.

When I first got them from the fabricator, I bought myself a rotary tool to try to finish them off but I sucked at it and they didn't turn out well so I am looking for a better solution and I dont' want to send out a ****ty product.

Tumbling them in a typical brass cartridge case polishing setup is not going to get them a shiny polish.
I have tumbled machined parts in my case tumbling setup and it didn't work good.
You need to send them out for electropolishing or some sort of plating that will leave them shiny.

Is there anything that WILL leave them shiny? If it works for brass, why would it not work for stainless steel?

As "ar15barrels" aptly suggested. In the post above yours. Electropolishing would be best bet for your requirements.

http://qfinh.com/electropolishing/

Electropolishing is a controlled electrochemical process utilizing acid electrolyte, DC current, anode and cathode to smooth the surface by removal of metal. It is considered the ultimate form of passivation as it not only removes iron and nickel from the stainless, it leaves behind a chromium rich surface (passive layer) as a result of the process.

It levels micro peaks and valleys to produce a clean, smooth sterile surface. Corrosion is eliminated.

Manual polishing of stainless steel, or any hard ferrous metals requires abrasive compound and high speed buffer wheels. And on hook shaped parts can be dangerous. As anyone who has had a wheel grab a part can attest.

Where as "brass" is a very soft and malleable metal. That is easily polished by the much more gentle process of a vibratory polisher and corn cob or walnut shell media.

Or a rotary tumbler with stainless pins.

Both of which work well for cartridge cases.
