Hi Nunes, I have a Gy-Roc tumbler system. I saw it when I went to
school at William Holland and had to have one. The main reason I
got it was because it was easily adapted to a flo thru system to
keep everything clean, and it has a top to contain the bubbles if
you use a soapy solution.
If you need a picture , hollar and I will gladly send you one, but
here is what I did good (and not so good).
1) I ordered the small Gy-Roc system, it will hold about 5 lbs of
shot and it tumbles jewelry great.
2) It also can be stacked, putting 2 more tumblers on top for a
total of about 9 lbs or more of shot, rocks , whatever.
3) I went to HomeDepot and bought a small, 2 gallon per minute,
water pump. These can be adjusted to pump less, or you can use a
4) I also bought about 10 feet of quarter inch (BC) clear plastic
5) The final purchase was 4 quarter inch (BC) hose fittings with
barbs for the hoses. The hoses slide on these barbs and pretty much
stay there without any kind of clamps. The hose fittings have a
collar on them , which keeps it from falling out of the tumbler if
inserted from the inside.
6) I drilled 4 holes in the top of the tumbler barrell about an inch
from the top. One is for input from the pump, and the other three
are for draining. Be very careful where you drill the holes, so as
to be out of the way of the frame of the tumbler....( I learned this
the hard way. I drilled mine at 0, 90, 180, and 270 degrees and
one of the barbs hits the frame of the tummbler.) You need all the
drain hoses to keep it from overflowing.
7) I put the fittings through the holes from the inside, used 5
minute epoxy to seal them, put on the hoses, and put them all in the
8) I got a 5 gallon bucket, and put the pump on a brick about 4
inches from the bottom, filled it with burnishing solution, and let
it rip. It works great.
9) The only other thing I did wrong was to mix my stainless shot
with my polished steel shot. It rusts. I'm going to buy all
stainless shot so I dont have to do clean up after I tumble.
10) Last thing, is it helps to keep the drain hoses above the level
of the water in the bucket, as sometime it creates a bubble lock if
its below the water surface, and it wont drain/ overflows. I guess
you could put three hose connections on the bucket at the top to do
this. Think I'll do this when I get home tonight, and will let you
know how it works.
Love and God Bless
