I've been looking for one of these for a while - thought it would be something I made myself out of a Poly arbor but this is good too. Spotted this in a local Craigslist ad late last night and started frantically texting the guy. Met up with him this morning and for $125 bought the Lortone arbor including four exact-span drums and two aluminum polish heads with leather. Also got ten 1/2 gallon jars of slabbettes and preforms.  Another case where the old dude passed away (rip) and his family was parting out his stuff with little clue about anything. He had a lot of wood-working stuff that I had no interest in - also has this saw for sale: sfbay.craigslist.org/eby/tls/5995857607.htmlThe saw looks great in person - the old dude kept good care of his stuff. I just got rid of mine - same saw - so I don't want it but someone could probably get it for $200 if they offered. |

Those arbors are really great. Our club had one with a sintered 80 and and a 220. Made a great preforming station.

Yeah I'm going to put my sintered 80 on it and haven't decided yet - either my expando rubber or one of these (new to me) exact-span wheels.
My other 4-wheel arbor that I've been using as a 2-wheel has literally been beat to death and needs to be torn down and bearings and sheet metal replaced.

I wish people sold lapidary things around here. I can get seashells, though.  ETA- Just did a quick look... there was no lapidary, but I found this under rocks norfolk.craigslist.org/jwl/5970710638.html LOL! See what I mean? |

Or does the west corner the market on those too. Seriously though - you already know this - you got me searching craigslist cities on the east coast and you aren't kidding with the lack of lapidary results. |

Tommy I hate you!!! Gallons and gallons of preforms and slabbets!!! As if you needed another reason <rolling eyes emoticon> Seriously though most of the rocks look like junk except a hunk of boulder opal I found AND about a gallon of what could turn out to be jade. The old man loved his green rocks haha. I've been trying to bone up on how to identify jade. |

How to ID jade.
1. Give to Bill
2. Watch Bill saw, preform and polish a cab.
3. See Bills ugly orange peel cab that is undercut!
4. Yes that is Jade!

LOL yes I've had similar attempts at it - never again. I don't enjoy working for hours on a stone and ending up right where you started. The old man did love him a green rock haha.  |

Jade's easy
After hard diamond use SiC belts, no diamond to 600, then a worn out 600.
2part Linde A, 1 pt Tin oxide w a pinch of cerium, slurry with vinegar and polish on leather
Get it hot.

Hey Rockoonz where you been?? Goin to be in Orrgon/Washington if all goes well this summer, I will give you a holler. I am going to write this jade tutrial down. Sounds awful easy. How do you dop the stone so that getting it hot doesn't fling it across the room?
I had another guy tell me to use a dry worn 600 belt.

I dop with epoxy or double sided tape, never could figure out wax. I hope you make it out. |

If your touch is light enough you don't have to worry about undercut or orange peel, but then the problem is you can't push it into the soft wheel to round out the flat spots. I imagine the jade you had success with had a higher quartz content. I recently got some Turkish purple jade that works up nice on the genie. |

Yes, Turkish jade is one that I didn't have much trouble with. |

ETA- Just did a quick look... there was no lapidary, but I found this under rocks norfolk.craigslist.org/jwl/5970710638.html LOL! See what I mean? LOL seashells and sand dollars? Or does the west corner the market on those too. Seriously though - you already know this - you got me searching craigslist cities on the east coast and you aren't kidding with the lack of lapidary results. Northeast is especially difficult when it comes to rockhounding; besides geology it may have something to do with population density and the relational lack of free land; it may have something to do with the lack of Government owned land since privately owned land is more or less off limits to collectors. If you are persistent you will find occasional collections and equipment for sale but rock hounds are more scarce in the east. Living on an island on the east coast, I find one one supply nearly endless...beachstones. There is a lot of quartz on the beaches. As you might expect you have to work to find nice clear quartz but that makes the nice ones you do find that much more valuable. |

As you might expect you have to work to find nice clear quartz but that makes the nice ones you do find that much more valuable. That's all true, plus, in general, we just don't have much to find. Here in Virginia, the state stone is Unakite. If I go to the mountains, I might could find some... if I wanted it. Not too much else to find. If I go south a bit, to N Carolina, there is more to find. I've been told that because the geography here is so old and the Appalachians so worn that there just isn't much left but coal. Unfortunately, my beach is super populated. My odds of finding anything good are practically zero.  |
