8-inch wheels certainly not the inexpensive route for a hobbyist. All it takes to go big is patience, grasshopper. I plan on buying 1 wheel a month. In seven months I should have them all. Actually, I might be considering this as a money making venture someday. I have access to lots of rough where I live, have nothing but time since I'm retired, and can hang a shingle out in front of my house on a fairly busy road in a rural neighborhood full of well to do jewelry wearers who live in the multimillion dollar homes down on lake Michigan less than a mile away. They drive by all the time in their Caddies and Beamers. I plan on specializing in Michigan rocks like Petoskey, Septarians and Pudding stone which the local people and tourists both really seem to like. Plus, I have a contact in Arizona for stuff like turquoise and southwestern stuff who gets it to me cheap and sometimes in trade for Petoskeys. Big plans. My kinda man.

Not threading your shaft? One of my first arbors was a home built (not by me) 2 wheel arbor that used shaft collars, when I got something better it went straight to the scrap yard.

I don't think a machine shop or fabricator would charge much to thread shaft ends but I could be wrong. I can't imagine wheels not slipping if only thrust collars are holding them.

Hate to rain on your parade again but the wheels I got from Han for the club shop lasted about a year before the plated diamond bubbled off.

I've had good success with plated wheels from lapidarytool.com. Iv'e been using my current 220 & 360 for almost 5 years. The soft wheels are a different story. They don't last very long, but I re-coat them with diamond powder & epoxy. Cost is minimal, between $0.28 - $3 for each wheel! Lynn

They don't last very long, but I re-coat them with diamond powder & epoxy. Cost is minimal, between $0.28 - $3 for each wheel! Lynn Yep, that's the supplier I was looking at. If I could be somewhat intrusive, what all is involved with re-coating them and where do you get it and how much does diamond powder cost? What kind of epoxy do you use. I'm all for saving money and I'm not afraid to try re-coating myself. The upfront cost of the wheels you're talking about seems reasonable. How well do soft wheels work for cabbing? Do you get the diamond powder in different grits? Rick, Here's one thread of many. forum.rocktumblinghobby.com/thread/27289/refurbishing-diamond-wheelsMany different methods are described. You can learn from everyone. I coat 3" wide belts directly on the Expando drums. No need to take anything off the shaft unless I need to start with a new belt. I replace them after a few re-coatings when the belts get thick & less pliable. I found a 30 minute slow cure epoxy from Bob Smith Industries. Any similar epoxy should work. I like that this one doesn't smell like mouse pee. I mix epoxy & diamond powder on a piece of flat glass. That way I don't lose much goop to a hard-to-scrape container. A putty knife will get almost every bit of the diamond goop off the glass. Then acetone to really clean the glass. A few years ago I paid $0.40 per carat, but now I've found much better prices. Ebay has some good deals. I use 10 carats on a 3" x 8" drum. Lynn
