Here's the reason I've been asking for preforms of softer stones! I've been working on this lace agate for the past two weeks, and while it's far from perfect (lopsided outline, major undercutting of the bands, and a shallow central dome), I'm ready to put it away for a while. Thank you radio for sending me the agate when I was just starting out! He sent it to me mostly-domed, which made the work so much easier. I don't think I would hand-sand an agate starting from completely un-domed slab. I took it from 80 to a 3000 grit paper. Must've used up at least $10 worth... Front Back. I like it just as much as the front - maybe I'll make a double-sided cab someday when I'm less sick of it. Side Polish

OUTSTANDING. That's a beautiful cab. Congratulations. And I'm really impressed that you did that with sandpaper. Later I'll find you cutting these by hand ...

BTW, I like the signature: Rock fever is curable with more rocks. Sort of like, "my hangover will go away after this next six-pack". Just one more toke ...

Bahaha, I like your profile pic, paulshiroma. Certainly seems like it this cycle.

Thats how you get to know a stone. Takes a long time yes, but...... Looks great, well done.
I do all my stones from 400 to 2000 with paper. Then 14k and 50k Diamond-paste to finish them up (simply because the paste turns out cheaper than the paper as well as being super quick). But I do have 3,5 and 10000 paper in the ready should I not get the 30 minutes time on the machine.

What a tremendous work must have been, to bring that cab to that beautiful shape and shine only by hand! If you have the patience to do this by hand, I can only imagine how would your machined cabs look like. You should definitely make this step forward. It's a wander your fingers still look in such a good condition - fingerprints still visible. Or does someone else hold the cab in the pictures? Adrian

adrian65, I can't take all the credit. Arlen sent me a preform that was 95% final shaped and domed. Since it was also dopped, that spared my hands quite a bit! But I should point out that's my NON-dominant hand pictured... Can't wait until January - that's when the club shop reopens and I can UNLEASH MYSELF UPON THE WHEELS!

I wish I would have known that it was easier for you to hand work with the dop sticks attached. I could have left them on the Kona cabs for you. If you do not have means to dop them with wax you could always try super glue and a 16 gauge framing nail.

Oh. . . and a wine cork on the roofing nail. We don't want blood on our stones. Nice job. Tom

You did an amazing job on that agate. I hope you are healing well. It's amazing what we'll go through for beauty isn't it?

Chuck, that's what I usually do. Nail + superglue + no TSA!

that lovely done stone, Michelle! here's method I've tried its rubber back sanding block and that curvature could help with the dome plus I always wonder if the inside of properly curved bowl with fine grit may be useful?

Ed, I was initially using a rubber block and I think it helped with the doming, but not with the undercutting. Guess those tradeoffs are more apparent at very low speed. But I really like the idea of using a bowl! I'll try that next time, thank you!

as far as your undercutting problem goes Michelle I think you'd have to pull out a magnifying glass to show me and by the time you did that you'd have lost me i like what I see with my own 2 eyes and that's a good camera picture smooth

Nice job. May try sanding sponges in the future for at least the initial sanding. lasts longer than paper, easy to wash out and conforms to stone shape. I have used them to polish various rocks and meteorites.
