Great choice! Remember that an 80 grit diamond wheel needs to be broken in a good bit before you use it on good material. You have to use a piece of agate (one that you don't care about) to work the wheel and get all the high spots off. If you don't, you'll end up with some huge gouges in your cabs that you'll never get out. You may have to go through a few agates, actually, before it's ok to use on good stones.
Have never used the Kingsley wheels, so YMMV.

Would roughing out some quartz and amethyst for the tumbler work alright for that? I have quite a bit from El JeffA. My son and I have been excited to check the first batch every Sunday to see how they're shaping up.

hummingbirdstones THAT is why I had all that trouble. My first few cabs had deep scratches that wouldn’t come out. Thought I was doing something wrong. Well that’s great to know even though I learned it late!!

knave All diamond wheels, even the resin ones need to be broken in. Just the nature of the beast. Obviously, the higher grit wheels don't need it as much as the coarser wheels, but a good work out with an agate will knock those high pointy suckers off there.
I read very recently a post (can't remember who it was) that said they use an old dull knife to knock them off their new wheels. Don't know that I'm brave enough to try that, but it's probably quicker. Knowing me, I'd put a big gouge in my new wheel and wreck it.

I don't break in hard wheels. They cut more aggressively at the beginning. I got a few scratches with my top 80 wheel, but I leave some of the 80 grit work to a worn 80 grit Diamond Pacific wheel which is much gentler and need to make sure that it removes all the scratches from the Top 80. The jadecarver 80 grit are also more aggressive when new but don't present a problem and I can go on to the 220 grit. I had to break in the 600 and 1200 Johnson brother wheels and I had been using them for two years and they looked like new. I recently got a JB 325, 3,000 and 14,000 soft wheels and they worked fine from the beginning. I just used them and observed how they were doing.

I'll try rounding out a couple pieces of quartz or amethyst before I actually attempt to cab something. On a side note: if you pour your slurry out into a bucket to let it settle and reclaim the grit, don't leave it out overnight like I did. I found a dead squirrel in it this morning. Pretty sure that won't improve the tumbling process.

Lmao! Tell fernwood maybe that will solve her critter problems! Sounds like a good plan. That purple from Jeff is softer than our local Quartz and any agates.

Got my wheel in, only to find the plastic bit that holds the felt pad broke.

Got my wheel in, only to find the plastic bit that holds the felt pad broke. That stinks. I know you are wanting to get right to work. Post some pictures once you have the new wheels and everything installed!
