Ok, I will ask. What is the rpm of the low speed? Shouldn't have... the Gy Roc is a vibe.

Most questions are asked because you don't know. Now I know a Gy- ROC is a vibe. I found that out from the earlier post.

Changing speeds on the Gy Roc is easy , has a 2 step pulley , pop the belt off one groove and put it in the other . Always have 2 o-ring belts , one for each speed be. cause the high speed setting stretches the belt which makes it loose for low speed . I use low speed for most runs . Don't know if it is standard equipment, but mine came equipped with a white plastic guard covering the pulleys. I suppose you could undo the screws and remove it, but it looks like that will also remove the motor. I have been able to stick my fingers in there and shift it from pulley to pulley. It came with two belts, but so far have only used one. I may consider using only low speed, at least try it and see how effective it is. Low speed much easier on the ears!

The motor has a counterweight, which causes the vibrations as the motor spins. The pulleys adjust the speed - slow speed, gentler vibrations, faster speed, more violent.

That flimsy plastic guard just pushes on the threads on the bolts sticking out of the motor on mine . 2 model A's and a model B . If you have any questions on running , call the number on the instructions and talk to Lionel , the owner of the company . Super nice guy and willing to take the time to talk . One of the guards on mine was broke and he sent a new one no charge .

Good to see the water requirements rockpickerforever. 1/4 to 1/3 cup. The amount of water in a vibe is critical. The strange thing about a coarser grit is that it creates a thick protective slurry fairly quickly. For instance the AO 80 I must use a 1/2 to 3/4 cup for 14 pounds of rock to get a 2-3 day run w/out adding water. 2 tablespoons grit and 2 tablespoons Borax. Then about the same for AO polish, quite wet. Maybe the Borax allows wetter runs. Food recipe note a great point. wigglinrocks, seems like o-ring belts are popular on vibes. The Vibrasonic has mixed revues regarding O-ring belts. Some have longevity and some users break a lot of belts(me). The people that order factory belts have best reliability. Mine are not drive belt O-rings but hydraulic cylinder O-rings. A mis-application. 50 units for $33. Lasts 2 weeks. It takes nimble fingers to put new belts on without removing the hopper and flipping the machine upside down.

Most questions are asked because you don't know. Now I know a Gy- ROC is a vibe. I found that out from the earlier post. spice, the Vibrasonic drives a off-balance shaft. I believe the Gy Roc drives an off balance shaft. The Vibrasonic motor is 3450 RPM and has about 1:1 ratio turning the off-balance shaft at 3450 RPM. = 3450 Hz The Gy Roc has a 1550 RPM motor. But it has two pulley speeds. Maybe a 1:1 and maybe a 1:2, not sure, just guessing. 1:1 would turn off-balance at 1550 RPM(1550 Hz). 1:2 would turn it at 3100 RPM(3100 Hz). To adjust vibration on a Vibrasonic you adjust the amount of off-balance (amplitude). To adjust vibration on the Gy Roc you change the speed(frequency). Maybe graphs will illustrate. Changing amplitude and NOT frequency: Changing frequency and NOT amplitude Too much amplitude beats up rocks, shakes too vigorously. I know this form adjusting the Vibrasonic. Higher frequency is probably safer, and may speed things up. If you had a say double 3450 + 3450 = 7000 Hz vibe with gentle action it would likely finish rocks twice as fast. But a shaft spinning at 7000 RPM is like a jet engine and presents a lot of reliability and noise issues. It could certainly be done with good bearings. No vibe has ever delved into such speeds. Maybe some day a hot rod person will build an ultra-sonic vibe. Ultrasonic motor, at 20,000 Hz a human can not hear, however the rocks would be likely very loud lol. en.wikipedia.org/wiki/Ultrasonic_motorUltrasonic motor is kinda like a stereo speaker.

One of the guards on mine was broke and he sent a new one no charge . Ah, thank you, Rich! That is good to know! That would make it so much easier. I would have broken that flimsy plastic guard sooner rather than later working around it. It did not come with a diagram or any paperwork other than the guidelines I posted. I guess I was in kind of a hurry to get it started, didn't have the time to dissect it. Since changing speed with the guard off will be so much easier, I think I'll do that and finish with the polish on these, then finsh up the rest. Thanks again for the info! Jean

Jean The directions that come with the Gy Roc is pretty minimal . The intensity of vibrations can also be adjusted by adjusting the counter weights on the shaft but changing the belt is good enough for me .

Again, thanks for the info, Rich. I took a quick look at it this morning when I added a little water. I see what you mean about the guard just lifting straight up, cool! Will make it so much easier!
Now I just have to wait nine hours (as per the recipe), then I need to clean it up a it, get all the schmutz off that crept out from under the lid. Will move the belt, do another cleaning with powdered detergent, then on to the polish.
Yay! Second batch in almost forever!

It takes nimble fingers to put new belts on without removing the hopper and flipping the machine upside down. The factory belts are more clear type of rubber or something and seem to last good . I have been running a set for 2 years . One machine I got used came with some extra belts that lasted only a day or two and they were factory belts . I think they were old belts . I talked with the company owner about that , he said when not in use store the belts in a ziplock in the freezer . The belts dry out and get brittle stored out in the open air .

If ya have any more questions , feel free to ask . I am far from expert but I have been using GY ROCs for awhile . One other thing , the directions say 1 rounded tablespoon , cut back to a level one .

And here I was thinkin' that I was goofy storing my belts in the refrigerator. My rotary stretches the belts out, probably because I run the barrels so heavy. Stretched belt = slower rotations. Putting the used, stretched, belts in the fridge gives them a second life.

By your own admission, James, it seems you are more familiar with the opposite of that, lol. Gotta watch those little indiscretions.

Properly motivated however.... I might have seen an enema bag in Bob's truck, or maybe it was a wine skin. Or maybe he uses it for both.

Searching for that post. Was reminiscing just recently about something that happened in the past, you said that was about the time you got thrown out for indiscretions. I remember that part, just can't remember mthe rest of it. Yeah, I got CRS, too. God knows you are getting old, jamesp. Heck, you are a year older than me now, lol.
