30 grit!
Thanks for the knowledge.
Just bought a gyroc. Getting my tumbler back in shape next day off. That is my reward for putting my new closet doors in!

30 grit! Thanks for the knowledge. Just bought a gyroc. Getting my tumbler back in shape next day off. That is my reward for putting my new closet doors in! Happy tumbling. Looking forward to your crafts. Will look up the Gyroc. Just looked at it on images and like the gyroc design John's Gems mentioned that it has a motor driving the separate shaft carrying the counterweight like the Viking. Good design. Some vibes have the counterweight on the motor shaft, some motors do not last with such. is this the one ?  |

I got mine with a dual piggyback design. This way I can vibe all three stages at once. With my 12# doing rouugh and the weekly cleanouts feeding the various stages. |

piggy back ? Got pics/images @shotgunner ?
Also like the long legged stable frame. Seems very clever arrangement.

Three bowls stacked vertically. That is why i made that purchase. All stage running at once. Vibration is heavily altered by the mass. A primary variable in vibration equations. The Viking and Gyroc can handle different weight hoppers and still tumble well. Says a lot about the flexibility of the process. Was aware of this when I built the homemade that never has been dialed in yet. You would think that tripling the weight would mess with the vibration characteristics. But to overcome the heavier weight you adjust the counterweights. So, do you adjust the counterweights on the Gyroc like you do on the Viking when running 1 or 2 or 3 bowls ? The Viking has an issue with piling heavy stones to one side; it is a cylinder bowl. The Gyroc has torus shaped bowls that are known for better mixing of sizes. |

Before leaving the shop last night to watch "the" ballgame (ROLL TIDE!!!!!!!!!!!!!!  ) I decided to slide a piece of 4x4 under the non-motor end of the tumbler that the barrel favored. I turned the barrel around and slid it to the "unfavored" end that the motor was mounted on. I positioned the end cap just a tiny bit away from that end roller and watched it slowly begin to move in that direction...not uphill!!! Apparently the the added dimension of a 4x4 made a difference!!! I figured it'd be good for the time being, plus the (2016 BCS National) Champion Crimson Tide was calling my name so I left it like that. I came in this morning and checked on it. What I found was dramatic!!!! The barrel had moved about an inch away from the roller and was sitting there happy as could be not touching either roller!!! There is more incline that I really want so I'm still going to install a different, better roller so I can get it closer to level, but for now...it's idling nicely along. Or, it could be that nice Hardee's cup making it work better.  4x4undertumbler by Intheswamp, on Flickr |

It is interesting in that I just looked at it again and the barrel had moved closer to the roller...only about 1/4" away now...I know it's been rolling against the roller from the black ring mark on the end cap so I guess it's travel a bit back and forth. I'll watch it today and see what it does.  4x4undertumbler2 by Intheswamp, on Flickr |

Good on you Ed. Looks like you got it stable. You reached the point of diminishing returns.
Try to use a flat wheel and bend it's bracket so that it 'impinges' flat on the end cap.
Has your creeks started dropping from flood level ?

Yeah, I've eyeballed a piece off of some old (cheap) handtrucks...no bearings on wheels but the price is right. The creeks are dropping, hope to get to them before long. The local ones are almost back in their banks. Of course it's supposed to start raining again.<sigh> Ah well, we'll get some extended pretty weather before long!!! Don't want to aggravate the deer hunters too much (they got scopes on those rifles, ya know!!!). |

After reading this thread I got to wondering about the added incline of the 4x4 block I slipped under the "favored" end of the tumbler. Could this possibly cause the grit to settle more to one end of the barrel? jamesp, I know you keep your barrels inclined and you have great tumbles. I'm figuring the 4" rise is around a 6-degree slope. Have you ever noticed grit possibly gravitating to the low end? It seems that in a fresh tumble with little or no slurry that the grit would be more prone to settle towards the lower end of the barrel...once there is a slurry I can see how the stickiness of the slurry would spread the grit around. Also, due to the incline, have you ever noticed a "classification" of larger/smaller rocks taking place...larger or smaller rocks segregating themselves from their opposites? Interestingly, with the added incline the barrel continues to wonder back and forth across the shafts, primarily in the center portion but will travel to the downward side on occasion...and towards the high in very rarely. No rhyme or reason that I see for this. I feel that the spinning/tumbling fluid content of the barrel is definitely contributing to this and wonder if the incline along with the spinning action is causing the rocks to spiral upward (or downward) and once at one end of the barrel make their way back to the other end. Basically moving in the normal tumbling direction but also a lateral movement that might be contributing to the "wandering". Just some thoughts this morning....I guess I really should break out the Hardees cup and see if it can help explain all of this.... |

The barrel is possessed... It has started climbing the hill and getting against the upper stand-off roller. The rubber end cap is rolling with the rubber clothes-dryer wheel...seems to be postioned nicely and rubber against rubber...no real sheer. I'll watch and see what it does. Strange that suddenly it has started climbing the slope so aggressively.  |
