I use walnut media with a heavy dosing of liquid chromium oxide and see pretty good results.

Sorry, haven't been around in a while. I wouldn't normally bring a thread back after so much time, but since the question was left to me...

The pyramid media did work a lot faster than the walnut...

It looks very similar to some media I picked up from Rio Grande. Overall it worked pretty well after adding some water in to get things moving a little better. In retrospect I'd would probably have...

I got it from Rio Grande. It was about $20 for a quart. I used maybe 1/3 of it for two loads of media (1 corncob, 1 walnut).

Ok, I have a little news to report. I threw in a russian blade I got off eBay and had it run for three days. The result:
...

I agree. If I was in the business of restoring razors this method would probably be a little too slow for my needs. But I'm not, I'm just a code monkey that likes to pick up interesting little...

I'll give that a shot. thanks! A night in walnut loaded with CrO cleared it up, but I'd prefer not to have to deal with it at all.

Yes, that might've :) My next test might be without the water. I was also considering using mineral oil instead of water.

Being an engineer, I like to @#%^ with stuff. In fact, I'm sure 99% of the people on this forum do or we'd have some other more boring hobby :)

I decided to take one for the team and buy some...

I haven't had this issue at all, but I also only put two razors in at a time.

As for scales on/off, all my attempts have been without the scales but logically it seems to me that it would...

Day 2. Walnut is definitely making a dent in the 280 grit sanding marks, but not as fast as I'd hoped. I decided to throw in a Russian blade I had sitting about to see if I could safely tumble two. I...

You read it correctly. I was just mixing it up a bit to see what happened ;)

I do have a question regarding media flow in the Midway tumblers. The bin doesn't seem very rounded. Do you get a good movement on the media when it's running? My bin is rounded and it really whips...

So it's been 23.5 hours give or take. Just got home and took out the blade for inspection. Looks really good! A nice polish, but some of the scratches from my 300 grit sanding are still evident. I...

The blade's just a humble round-pointed wedge, but I appreciate the quote ;)

So I broke down and checked it at almost 2 hours, and all I've got to say is WOW!

Parts of the blade are already starting to develop a great finish.

The blade I'm throwing in there is in great shape to start with. I really only needs a finishing polish. I'm starting out conservative since I'm not used to this technique. I can always go back to...

Corncob goes in the tumbler, Flitz goes in the corncob. Blade's in the tumbler. My blade.


Will report back in 24 hours.

My order arrived today also and is sitting on my doorstep waiting for me :y

Unfortunately I still have 20 minutes left at work, then an hour and a half of gym time before I get to play.

This happened to be the same brand I ordered and the description I found online for formula 2 was "Ground corn cobs. Combined with a chromium oxide cleaner and polisher."

Just an FYI.

I imagine a rotary tumbler would be too aggressive for this kind of application. From what I've read about rock tumbling, a rotary tumbler will round off the rocks while a vibratory tumbler maintains...

I have another question (yep, another) regarding the engraving you had on your blade gssixgun. Is there any noticeable difference it it after being put into the tumbler? I get really nervous with...

My order is en route too. This should be an interesting experience.

Thanks to everyone who has contributed to this thread, especially gssixgun :y

Next question...

How loud is the Frankford Arsenal tumbler when it runs? Unfortunately I have no garage :( so it'd be running in my basement. The master bedroom is pretty much directly above...

I saw your link, but I was just looking at my other options. I hadn't decided on any particular brand yet. Thanks for your advice :)
