Recommend a good 7 liter or so rotary tumbler.

Have you seen these smaller ones ?

Although, I think they are Chinese made.

And I see tumblers as well.

Dualkit, Why do you want to stick with rotary tumblers? Before anyone doubts my redneck credentials, we flat wore out three Harbor Frieght concrete mixers before moving to vibratory. On one the tub fell off, the bottom was just gone. 8 hours a shot, two runs a day. (We killed a couple 18lbs HF vibatory bowls in there as well)

We finally got a Mr Deburr DB300, and it is better in every respect. Faster, better quality finish, more convienent. We recently got a second to keep one set for stainless and one for aluminum. I'm sure the big round ones have advantages, but for a small shop the Mr Deburr is great.

I want a rotary that size for convenience of use for the parts I commonly tumble. I have two bad shoulders and a fused spine. Working with a removable barrel of 30# or less when full works best for me.

 

[Delw]

wouldn't a mr debur type tumbler be easier on your shoulders and Back?

I am curious about useing about the blast meadia you said you used in your tumblers. what does the finish look like.
I thought about trying stainless steel pins but got a quote for them to fill up and it was close to 8k, I might try some steel shot (shotgun shot)in bb size as I am curious what the finished would look like.

I thought the round vibe bowls can have a chute you drop in to lead the parts out, over some grating to let the stones fall back in,
and parts go right into a bin.

Not the one I have you have to pick it up and dump it. Loaded with media, parts and the bowl it is probably 40-50#.

They need to go a little longer, please excuse me, I am the world's worst camerman. That is with glass bead, you can turn around and use walnut shells to polish them up. Material is 4140.

The link I posted shows the smallest one have a door. You open it, and it all dumps into a sorting tray.

But the larger ones can take just the parts up a ramp, and out.

I believe some of your parts are small enough that you could buy a HF single barrel rotary for a measly $52.99 + tax to use to experiment with media in. I have a double barrel one that I use for small firing pins. I don't want to pan for gold with any more media than I have to. The single and double barrel ones use the same size barrels, they are approximately 4" round by 4" long. If you want I will send you a 5# bag of SS pins for the cost of postage I got as a throw in with a tumbler I bought and have no use for. That will easily fill one of those small barrels and fit in a small flat rate USPS box.

oh your trying to polish them, makes sense.
I use'd corncob for brass, and copper parts tellurium, beryllium and normal and alum nickle bronze it works really good but like you said earlier takes alot of time..

A trick I learned 20+ years ago. if you take a few dryer sheets cut them up into 1" and 2" squares and toss them in the dusty build up on the parts will dissapear. works both for walnut and corncob medias.

I also have dropped a cap full of mineral spirits in when doing brass (reloading and machining brass types) it will make them shine and cleans them very good. it will stain coppers

Thanks for the offer, I have a few lbs of ss pins I bought to try on reloading, just havent used them yet

I think I have requested a unicorn. Looks like "well made" rotary tumblers with screw on lids don't exist in the size I want, they are all plastic drive geared junk. With the largest piece of round material I have laying around being 4.5" and needing a 4.75" disk to put on a stem I have asked a friend to dig one up and I will just use my geared head lathe as a tumbler. The local metal yards don't sell remnants here. When I was in Cali I had a place 10 miles from me that had remnants up the wazoo and lots of small precuts, even disks. I miss that place.

 

[Delw]

asking for something well made anymore is tough to get, ya just gotta build one yourself if you want it done right.

US Plastics might have a tub or barrel that would be the right size.

For the quickie gas tank deal I posted, I bolted a piece of plywood to a welded 1.5" adapter then steel banded the tank to the plywood.

I'm not proud.

Unfortunately I gave away a couple gear motors I had and scrapped a bunch of other items that would have been handy a couple years back during some spring cleaning. It seems over the years the hex 12L14 I get locally has gotten rustier and rustier. Maybe I am the only one that buys that size and it is all coming from the same pile in a warehouse without climate control.

I am struggling to insert images and text. The above is what I ended up with, a lathe tumbler. I figure the lowest speed of 70 RPM should work.

Who makes that container?

After you insert a picture just click on the image and the resize dots will show up, then just click and drag to resize. You can add text by clicking behind or in front of the image. Im getting ready to buy the image gallery add on for the forum so you can place all the pics in a folder and upload at once and that may help with the text issue.

It came off a Frankford Arsenal tumbler that stripped the crappy plastic gears trying just shy of max load the first day I used it. I just made a couple doodads to mount it in the lathe.

I found the drum, heck that was close to half the price of the tumbler:https://www.frankfordarsenal.com/ca...umblers/spare-rotary-tumbler-drum/909789.html

My first try I somehow ended up with 4 sets of full size and thumbnails, don't know how I managed that.
