Well what I am trying to do is balance the weight on each side, but you are bringing up things that I am not considering. Back to the Drawing board. Personally I would never put wheels out of order either. In other words If I had a 17 pound 60 grit wheel and a 17 pound 220 grit wheel I would not want them on opposite sides of my cab machine. Being able to go from left to right in order just makes more sense. When you get into cabbing you will find yourself needing to back up a wheel every now and then and having them in order helps do that easily. A poly arbor (very heavy duty) or even a Lortone (2) place arbor would be my first choice (If I could afford those two sintered wheels). lortone.com/collections/arbors/products/stainless-steel-arbors?infoChuck |

Hans' wheels don't seem to be that dynamically balanced. So even with the slightest imbalance, having wheels this heavy mounted on an arbor that is only "fixed" on one end allows for too much vibration which can cause premature wearing of the arbor bearings and cause damage to the arbor shaft which can contribute to increasing the overall vibration. Plus if the vibration get's bad enough the user will be having a lot of stones fall off dop sticks, especially if dopping with wax. Better to mount these heavy wheels on a section of arbor between two pillow block bearings (like the old HP, Star Diamond, Barranca, and some models of Convington machines). And to minimize machine vibration, when mounting multiple wheels on the same arbor use the hand spin balancing technique described in many of the machines owners manuals for balancing a shaft with multiple wheels before tightening them in place and using.

Larry C. That makes perfect sense. It is good to get first hand knowledge. The other issue with having the 60 grit out at the end of a shaft is that that wheel is the one I press the hardest against. Back when my local rock club was up and running they had those two sintered wheels mounted to a lortone beaver arbor. I don't remember hearing of any issues. I really liked that arbor and would love to find one used. The beaver version seemed way more heavy duty then their normal 2 wheel arbors. Chuck |

Does anyone know where to purchase 8" Steel Wheels in 600, 1200, 3000 grits? of course NON SINTERED. Crystalite makes a 600 grit Crystalring hard wheel (and makes finer grits in flat laps). Not sure why you would want anything finer than 600 in a hard wheel for cabbing. I've got a 600 grit hard wheel mounted on my machine but the only time I use it is for rough shaping turquoise or opal. For finer grits when cabbing I use soft wheels.  Larry C. |

If sintered wheels get worn from improper use you can use a dressing stick to flatten them out. You will lose diamond though. What kind of dressing stick do you recommend? I've been using the white ones for diamond wheels from Kingsley on my 220 Neosint. It doesn't cut like it did when new and it's only a couple of years old. |

I can see that the weight might wear the left-side bearings more than the right, especially on the newer machines. They don't build 'em like they used to. But so far so good. I'm running a plated plastic core wheel on the left side as well. The good news is I'm only a couple hours' drive from the factory in Barstow, CA where I had my bearings replaced 10 years go or so. |

I called Cab King today and they said they have customers that use 1 Steel Wheel on their machines for years with no problems. For that matter many users on here do. I am in the middle of getting a credit for the other two Sintered wheels and will just go with the one like everyone else does. Thanks for all the good Info!  |

Does that mean you canceled your order and you're going with Inland? I'm going with the aluminum Inland wheel myself. |

Inland recommends an 80 grit (if I remember right) for the sintered wheels. It was a brown stick. Reentel had the "Neosint" wheels (and still had a few in stock a while back) but bought out Inland last year so now only list the made in USA Inland sintered wheels (higher priced). I know several people running sintered and Barranca brazed diamond steel wheels on Genies and Titans. If Hans wheels are not balanced that would be a good reason to pay more for better quality. Except for maybe hogging off material I can't imagine making quality cabs with wheels/machine jumping on the table.

Has anyone purchased from Baltic Abrasive Technologies? At this point it will most liely be either them (Baltic) or Hans. |

So Duke, what kinda rock was christening those new wheels?
Something Mohs 7? Agate?
How far did you get with it?

I ordered three 8 inch wheels on Saturday; 80 and 220 hard and 280 soft. I bought the hard wheels from Jadecarver from his site.
I've used these wheels for quite a while and like them. I bought the soft wheel from Baltic on ebay. I would have preferred a 220 but I'm not paying for a Nova. The three soft wheels were purchased from Johnson brothers 4 1/2 years ago. I got a 220, 600 and 1200. I was very satisfied with them but heard the quality has gone down hill. My 600 and 1200 show very little wear. The 220 is used heavily and shows it. I bought the regular 280 instead of the rez. I may try the rez next time. I need to order a 3000 and either a 14,000 or 50,000 for my Genie. After a long break in the 50,000 DP Nova works well. If I choose a 50,000 I'll probably need to order it direct. I bought a 6" 325 soft wheel from johnsonbrothers 4 years ago that I mounted recently and it is getting broken in. I'm using it to fix girdles and face scratches. I like it.
