For some reason I laughed when you dropped the barrel when you were rinsing in the first vid
Also, your surprise on how "dirt" the water is, "are you kidding me..."
You did an EXCELLENT JOB making the video and TELLING people WHAT you did from start to finish
When I first tumbled, I was ALL OVER youtube trying to get how/what people did to mix/prepare etc etc etc and got bits and pieces of information from NUMEROUS videos. Yours is ALL IN ONE VID (i.e. talking about the first one that is because the second was for "recleaning"). A few things from my experiences of what I've read and tried and experimented with:
1) read: I've read NUMEROUS times from NUMEROUS sources NOT to exceed the poundage of the rock tumbler capacity as for some reason it is hard on the belts and they will tend to break. Yes, they gave you extra belts, but why do it if you REALLY don't need to. It's like taking your "regluar" 4door sedan and go DUNE HOPPING with it or ROCK CLIMBING, you get the point. Needless to say, the car won't LAST very lone
2) read: I've also read from NUMEROUS sources that the "dirty water" contains "HEAVY METALS" and that NOT to come in contact with the skin as this is, obviously, bad to humans. Is this true, I don't really know
Have I come in contact with the "dirty water", YES. MANY TIMES OVER
I haven't been "twitch'n" yet so things MUST be okay, thus far
3) experimented with: I experimented with the same combination of aquarium rocks and dish soap, but also added in a little bit of PineSol and Comet. Your clad coins will come out "blinding you". Comes out pretty clean.
Hope these experiences of mine help. HH \_
BTW... don't forget about possible rocks in your, I'm assuming, garbage disposal.
