This is a sexy looking variable speed controller TheRock . Have you purchased this unit ? Yes sir just finished the post. All you see here in the picture is sitting on my center Island bench in the Pristine  Lap Shop. By the way that was one hell of an impressive scrap yard you get to shop at! Id go nutts if I had something like that near me! WoW! |

Id go nutts if I had something like that near me! WoW! That unit would have saved me a bunch of time fooling around with pulleys over the years. I finally found the speeds I needed over the years for different steps, slurries, abrasives, materials, barrel sizes, etc. But there is a pile of sheaves and motors sitting in a scrap pile from all the experiments. Lots of time spent. It would be nice to change speeds. No doubt. For a plethora of reasons. About the only thing I tumble is glass and Mohs 7, so the speeds needed are about constant. I would like to graduate to a neater tumbling area. Especially since down sizing the amount of tumbling. I pretty much do the tumbling in the weld shop since that is where I spend most of my working and tinkering time to keep an eye on it. |

TheRock Those salvage yards are being sold for the urban land value. One of them has a high rise going up on it. The other just sold and they will be liquidating the whole 5 acres of goodies within 6 months. Depressed about this. I have been shopping there for over 30 years. Wife too. We made half a living buying stuff there, modifying it and re-selling. The availability of industrial components priced so low has allowed me to be self employed for over 30 years here at the farm. Fire pit tooling and materials, aquatic nursery plumbing and electrical, materials and found items for fabricating industrial loft furniture, etc, all tooling, plumbing, electrical, welding materials, building materials came from those 2 places. You being technically minded would know the value of the stuff there and how to utilize it... I can walk in there and for about $100 and 2 hours time have enough steel, bearings, pulleys, a motor and shafts to build another tumbler pictured in this thread.

rockbiterI found the photos of the metallurgical grade silicon carbide. Carbolon MA I had to pull a trailer from Atlanta to Birmingham's steel district to purchase it. They happened to have it in 50 pound bags (and 4000 pound bulk bags). I believe it is only 25 cents/pound in 4000 pound bags. $1000 for 4000 pounds ! I did not want to wrestle with the 4000 pound bag however I should have. I bought $700 in 50 pound bags at 45 cents per pound. About 1500 pounds. Done, no more coarse grit needed for life. I could have simply dumped the 4000 pound bag on the ground and put a tarp on it. It is just coarse grind abrasive no matter if it gets trash/dirt mixed with it. Someone could buy a crusher and easily crush and sift it to SiC 8-16-30-46-60-80. Why do that, the tumbler will crush it for you and grind your rocks longer. It is 3/8" and smaller, ungraded. SiC 8 is like BB sized, no telling what 3/8" is - SiC 000 lol ? Just remember it eats tumbling barrels if you don't crush it down. It also shapes rocks like no tomorrow.    Sifted:

He's got almost any grit you could need in AO and SiC.
220 AO works great in a vibe after shaping in the rotary. If you're doing the 220 in a rotary I have no idea.
I ran AO 500 and AO 1000 and AO 14,000 in a rotary. AO 24, AO 46, and AO 80 was useless in the rotary, doable in a powerful vibe but not effective excepting AO 80 for hard rock in a powerful vibe.. The Abrasive Armory is the best place to buy AO 80, AO 220, probably AO 500. I have used 3 to 4 sources for buying AO 80 and AO 220. From sand blasting grade to high quality screened AO(for precision finishes) suppliers. They all worked the same(in my vibe). I am puzzled by your statement "AO 24, AO 46, and AO 80 were useless in the rotary. I use AO 80 on all of my hard rock in the rotary after SiC 600 and before Polish, no complaints. If it's Quartz crystals, Obsidian or Preforms and Slabs I substitute 500 AO for the 80 AO. I was considering 220 AO in place of the 80 AO when it runs out. Henry |

"were useless 'to me' in the rotary" Because I use the vibe for AO 80 and smaller AO's. Important point you make here. That larger AO 80 smooths after an SiC 600 step. i.e. AO is a totally different animal. That difference between aluminum oxide and silicon carbide is often misunderstood. |

Dang, that carbolon ma would be great if it weren't across the country from me. Shipping would probably cost more than the product.

Looking good TheRock! Are you throwing that motor on a tumbler you already have or building one? I got my sewing machine motor and energy meter and I think it's going to work out. 🤞🤞 I hooked up the motor to a small tumbler I have to see if the energy use was sky high. Amperage ramps up nicely with speed and even with two six pound barrels on the tumbler turning at what looked like a decent speed, I was only at about 45 watts - 0.4 amps, the equivalent of a 1/20 horsepower motor. It had absolutely no problem starting the barrels turning. With bigger/more barrels/shafts to drive it may end up using more amperage and I could end up needing to change out pulleys to get more power but that's a pretty great starting point! |

I plan on building one. I will base it on the Diamond Pacific 40T. It will be 36" wide and 3 to four tiers. That 1/2 hp 220V 3 phase motor is meaner than hell and will chit and get it.  You wouldn't want to try and stop it even with a wrench. If you do, you better have good dental Insurance.  So what do you plan on turning with yours? |

Impressive set up Bob. I went back and read that you are using a 3 phase motor.
Does the variable speed controller generate the 3 phase from a single phase input or do you have 3 phase coming into to your shop from the power company ?
No problem with torque at any speed with that set up.
Never mind, I looked it up. Looks like a 230VAC input is all that is needed for that vsc.
By the time you buy a good 1/2 hp single phase you can get a 3 phase motor and this controller for not a big difference in cost.
The industrial junkyards sell the 3 phase motors for 20 cents a pound.
No one wants them. Not in the past anyway.
That controller is a game changer because it makes the 3 phase motor doable for a home owner.

(I just used a 14 Ga 3 wire 10' Whip with a male connector on one end) for the input and plugged it in an outlet. Output is 220V 3 phase up to 1/2 hp max. How it generates 3ph 220V from 110V single ph is beyond me!!!! Yes it is a Game Changer! I am thinking about adding this setup for My Diamond Pacific 40T and run it a lil faster and switch directions once a day. It is a Bolt in Mod. The motors are the same frame and shaft size the change out and Mod should be a slam DUNK. That way I can get used to what it will do and I have a BIG DAYTON 20" Drill Press that has a 1hp Motor that I am thinking of modding!  |

If that device can sense power or amp load it could be programed to turn my slurries at maximum friction levels TheRock Bob. But it would have to have limits set for complete glue down if slurry gets too thick and rocks lock up creating absolute maximum power/amp draw. If it does not interpret power or amp draw I bet it could be speed programed to ramp over a 7 to 10 day period up or down at predetermined amount as needed to maximize slurry friction on rolling rocks. Often times I will put a freshly mixed batch of rocks and coarse abrasives and slurry additive onto the slower 28 rpm shaft to safely mix the contents for 24 hours at a safer slower speed, open barrels and check for proper slurry viscosity the next day, adjust slurry as needed, then move the barrel to the 60 to 80 rpm shafts to get business done. You may find faster grind times in varying rotation speed from 30 rpm to say 50 rpm every 2 to 4 minutes or perhaps at a faster rate. Anyway, those are some thoughts as related to possible beneficial speed variations between the typical cycles between clean outs. Sweet sauce man. 3 phasers rock ! ETA What protection does it have if motor shaft locks up as in the case of drilling metal with a drill press ? |

Building a custom tumbler for the barrels described here: Barrels I was originally thinking of making a fairly big tumbler until I thought about how much space, time and grit it would use to keep it going. Now I'm thinking I will be rolling two barrels at a time, 6-8" ID, 10-12" interior length. Each barrel will be on its own set of rollers, stacked and enclosed in a small cabinet. Needlessly complicated but should be pretty freaking sweet if it works out! I have it about a third built but I'm hoping to find a cabinet to mount everything in at the dump. Otherwise I will have to build one. I don't know why I can't upload a picture in a reply post but oh well, I'll just post pics when it's all done. |

This is a Motor that has adjustable rpm and rotation via an app using permanent magnet ECM technology. Only goes up to 1/15 hp though. |

Mars ECM CatalogPage 3 has the same setup from 1/5 - 1 hp. Page 8 shows the PWM speed controller for the Evergreen lineup of motors.
