My DIY Wet Tumbler
It's not pretty, but it's so much better when you do it yourself.
After a lot of research into what others have done, I decided to make a wet tumbler from a 4" PVC pipe, aproximately 3' long.
I used 3 pieces of 3/4" aluminum angle inside spaced evenly as agitators, secured with standard hardware and sealed with silicone.
One end is capped with a standard PVC end plug, the other is a rubber boot, with a hose clamp. Have to get into the sucker right?
I used an old Ryobi 18v cordless drill motor powered by an old 18v PC power supply. I chucked the drill with the small sprocket from a kids bike and attached the large sprocket on the tumbler canister. The chain was adjusted to fit. Currently using the trigger for speed control but, purchased a electric motor controller with a switch and speed dial for final wiring. It moves around 45-50 RPM.
The base is just 1x4 with 2" castors, 4 tumbler rollers and 1 to hold the end by the rubber boot. It has about a 3/4cant to it towards the back end where the boot is.
Pictures are of my first run, using 5 lbs of stainless pins as media, aproximately 1 gallon of water (about half full) and some Lemi-Shine dishwasher water softener. Results were amazing.
Not counting the media, I have about $30 in this, the stainless pins cost about $40 for 5 lbs.
(Note: I have a tumbler, been accumulating brass, building bullet and brass feeders, and plan to buy a Hornady LnL Progressive in the spring of 2016.)
