how to tumbler
I bought an old printer at goodwill for $2.00 that's right 2.00. I then took all the plastic of the outside and wired the drive motor directly to the power supply to get rid of all the switch mechanisms so it would run all the time instead of stopping when the paper was out. I use a kind of rectangular juice bottle so the coins agitate more . A hand full of play sand and some water and about four hours and coins are quite clean and I don't separate clad no copper transfer with just water , no vinegar or whatnot. sorry I don't remember what model you will h ave to look at the drive rollers to see if they look the right spacing HP i think you will have to change the bottle once in a while because as I found out the messy way they will where thru after 5 or 6 batches I would estimate I have cleaned about $ 600.00 in clad over the last two years and still running strong despite the TINY BELT. I just love being thrifty when it works so well. note round bottle did not work near as well.
