Horror Fright vibrating tumbler

[Toolmaker51]

That vibrating bowl is what 98% us cartridge reloaders use. For brass, common media is ground [DRY!] walnut or corn with polishing rouge. The grains are about size of coffee. No dimensional change, just burnishes inside and out of oxidation stains and powder residue.
The bowls will do machine parts with ceramic media. The parts work best if not too long or heavy. Til now unaware HF sold ceramic media. I do brass; and notice flow is best when level of material/ objects is a bit over half the toroid, where agitation is highest. Even the primer pockets come clean.

Rolling tumblers do great for the lapidary people, abrasive media like emery and detergent; that keeps the slurry moving as swarf collects, for awhile anyway.

Regarding Tony F's disappointment Here is a link to a 20 second video of my HF device working (or not working) with two different media loads. Compare that to the first 10 seconds of this video, it is little wonder than I am disappointed with my recent purchase. Time to improve another HF tool.

It's working alright, just not performing. And improving [re-engineering] unsatisfactory elements is our happy epidemic. HF and the others just don't realize they have the largest staff of designers available.
The bowls are nearly sure to be removable; access motor shaft and make a heavier eccentric?

It's working alright, just not performing.

This morning I loaded the HF unit and my Q&D rotary machine with the same weight of pyramid shaped media, a small amount of water and detergent. I added the same weight of components in each. Within one hour the stuff in the rotary tumbler had been deburred nicely and needed no more. It is now ten hours later and the HF unit is nowhere near the same results.

The bowls are nearly sure to be removable; access motor shaft and make a heavier eccentric?

Actually you can access the out of balance weight from underneath by removing only 3 screws. I did go looking for net feedback on changing the weight and it seems like bearings chop out very quickly, which is hardly surprising.

After studying the design I am of the opinion that the weight needs to go on to the other end of the motor. I need to check out if it is an easy job to simply bolt the motor in upsidedown taking the weight with it. It looks easily doable but I'll have to get more serious with the dismantling to know for sure.
