I posted a pic if this old Lot-o I picked out my neighbors garage a few weeks ago. Finally loaded it up with some pre forms and face polished specimens. Kind if experimenting and can't seem to get the Rick's to roll like my diamond Pacific and I seen on you tube. It vibrates good. It has a wooden dowel under the springs. I adjusted it and it will vibrates a harder. I replaced the dowel with one that wasn't flat on one side. I adjusted the way the barrel sits. Less water,more water rolls gentlely but I don't think like it should. Making slurry, but not as much as the vibra Sonic and the vibra sinuc is using 500 grit and Lot-o 220.

Try taking out all the rocks and just fill with ceramic media... see if you get any action. The same happened to me my first Lot-O run. I suspected that I had added too much Metamucil to produce a too-thick slurry... or I had added too large of rocks. I removed a few rocks and the action picked-up a little. I did a clean-out and just ran a load of large ceramic media - no rocks - no Metamucil... motion became a good slow roll. This showed me that the problem was not the Lot-O, but my load. I finally came up with a good ratio of ceramics to rocks... and VERY little Metimucil... I obtained a very nice liquid shine on a small bunch of Botswana Agates. Happiness! Could you elaborate on what the shifting of the wooden dowel did to your Lot-O action... curious. grumpybill mentioned that it fine tunes the vibe motion. Glenn

Another thought: Check that the weights are exactly aligned - both should come to rest at the very bottom when the machine is not on. Look inside those plastic flywheels and you'll see where they've glued weights inside. You can manually twist and adjust the wheels until they line up. The machine will really shimmy and shake and get loud when they aren't aligned, which can easily happen when the machine has been moved.

There is a short paragraph in the manual that came with mine that says something to the effect that the Lot-o is fine-tuned at the factory by positioning the dowel before gluing it in place, and that the dowel can be moved to retune it to personal taste/requirements. There's no further detail on which direction makes it more/less aggressive. I haven't played with it, but have thought about experimenting because I've gotten chips on quartz stones during the later stages. toiv0 : Do you have the critter solidly mounted to something heavy like a concrete block? I'll be emptying mine later today. I'll measure and post where the dowel is positioned on mine.

I'll be emptying mine later today. I'll measure and post where the dowel is positioned on mine. it mounted on one block, will get another today. Walked a little. The dowel under it is a 3/8 flat on one side. It was positioned as far away from the barrel as it could be pushed. In a couple videos it looked almost under the upright to the frame, as it is moveed towards the barrel it is has more shake or more violent but doesn't roll any faster. I put a new dowel with out the flat spot and didn't make a difference over the old one.

I just measured mine. From the center of the sheet metal screw at the motor end of the flat spring to the center of the 3/8" dowel is ~1 5/8". As far as I know this is how it left the factory.

Pulled everything out cleaned it up reduced filler a little. seems to be rolling better. Maybe had too much weight in it. Maybe motor getting tired.

Put rocks and media in, fill with water, drain very well, slowly add grit while running.
Things that can cause it to not roll the rocks.... 1- too much water, once running corectly use a spray bottle and squirter then wait to see effect b4 another squirt 2- broken spring, they are hare to see if broken. 3- stick not adjusted correctly, look at a pic on line and adjust yours by that. 4- fans weight not matched up, both fans have to have the weights at the same point , lay a ruler across and sight by it. 5- barrel worn and become soft so it sinks down and touches bottom 6- frame sprung and not holding barrel up high 7- mass of grit, rock and slurry lumped in the bottom all fused together 8- too many heavy type smalls will cause a lump to form in the bottom
Hope This helps

my barrel has a knob on the bottom,it's not supposed to touch? Nope. why would it be there about 3/4 round and protrudes almost an inch. Will try raising it up. How high should the barrel be.

Tore it apart,broken springs. Couldn't see them until apart. Thanks everyone.

The knob is there because the barrel started in life as a toilet plunger.
Good job finding the broken springs.

My new Lot-O is very loud under load. With just ceramic media acting as the load the unit is quite quiet... but add a load of Bots (50/50 with ceramic media), the noise seems to go up many decibles. The Lot-O unit becomes a bit too aggressive and vibrates the 63 pound cement block across the garage floor! The inner motion of the rolling rocks looks good. I now have it corralled into a corner surrounded by other cement blocks to keep it in one place. I think I will check the weights. Will I need tools to tighten their positions? Glenn

Glenn Hi Glenn - Glad you're holding it at bay! Those fly wheels are just held on by friction and can be adjusted by hand. They may be a little stiff to turn, plus they're a little delicate compared to other components, so just work at them gently until they begin to move. A good light source can help you see inside to be sure the weights are aligned. The one time my machine got a bit wild (loud, super shaky, less effective rolling action) I found that misaligned weights were the problem. Once the weights were back in sync, the beast was tamed again and purring like a kitten. Best wishes, Inga

Glenn Mine is not vibrating the cement blocks at all Glenn. I figured it would, I can set a pencil on the edge and it stays put and does not bounce. Sure seems all the vibration is isolated into the block and travels no further. Runs very quiet with no rattles or extraneous shaking.
