I built this out of things I had laying about.
The pillow block bearings were the only thing bought at the time. And the belt.
The rest was scavenged and painted.
I splurged and threw out the clothes hanging rod shafts and put one hardened steel shaft in their stead and two idler wheels. Even though it was working fine. I could build another with them, but I don’t see this wearing out. I can sit on it.
My first container leaked, so I did have to buy material for another. The new one has stainless baffles attached for increased agitation.
The pins are durable and it uses soap, citric acid and electricity.
I enjoyed building it, because I enjoy building.
The Frankford Arsenal Rotary Tumbler wasn’t around, but is a great thing now.
Though I imagine a human could build a vibratory tumbler, I don’t think it as rewarding a payoff, effort for results wise.
The investment was worth it.
