When polishing a stone using a leather belt and diamond paste I find that the stone becomes very slippery with a fine powder of atomized leather and diamond particles. Even worse, leather belts can be very ‘’grabby’’, pulling a stone right out of your hand and throwing it down with a loud nauseating thwaack. To combat this I have started to polish the edges of my stone first while I can still get a good grip on the larger front and back of the stone and only polishing the larger sections after finishing the rounded edges. While polishing the dome and back I find it helps to wet my fingers, NOT the cab, every few minutes. It washes off that diamond dust that makes the cab so slippery. It, um, helps me to get a grip! I do rinse the cab when needed.
I also intend to cut a piece of old carpet to fit inside my grinder pan to cushion the next cab that goes ballistic!

I think Stoner mentioned using a bit of silicone spray to make the leather less grabby.

Hmm would it be easier to use dop sticks so the belts don't hit your fingers and the stones are easier to manipulate? Personally, I gave up hand holding ages ago as I broke too many stones and couldn't spin the stones as well to avoid flat spots. I even use a slab grabber when sanding flat slabs for the same reason....mel

mel i dont do domes so i dont realy have to worry about flat spots i have worked acouple stones on a dop and its good for small stones but it just dont feel right to me (i know im wierd haha) but any thng i can hold safely id rather do without a dop-- it takes too much time and waiting to dop and un dop and if you realy have to shape something it gets hot and may pop off and then its back to waiting haha --hell ill take acouple hot fingers anyday to finish a stone in under a half hr

I used to do all my cabs by holding them in my fingers. Then this year when it started getting cold and my fingers tips started cracking, out of necessity I started dopping my stones. I felt the same way as John about dopping with wax, it just wasn't worth the extra time and effort. So I use super glue and an accelerator to dop the stones. There's no waiting for the wax to heat up or the stone to heat up and they very rarely fall off, and if they do, I just dry the stone, grab a dry dowel and re-glue it and continue working it. And actually I find I have more control over shaping the domes and I think my cabs have improved by dopping. The bad part about dopping is polishing the backs, but I can live with that. I just wish my fingernails would grow back! I can do 5-6 cabs in about 2 1/2 hours.

I tried the silicone spray and I love it! It helps a lot. I'm with Sands on the dopping. It sounds good in theory but I usually don't want to take the time to do it. I like holding the stone in my hand during all the grinding and sanding stages!

I have started using this Veternarian Bandage tape stuff- (you know- the stuff that only sticks to itself?) when damp it tends to be slightly "tacky" and gives me a nice grip on the stones- Joe what silicon spray did you use?

It's just some generic sorta stuff from the auto store.
I got fed up with tape so now I use some of those rubber finger things they use in offices for grinding and sanding. They protect my fingers real well!
Hey Sands, the first time I drew blood on the grinder I didn't realize it was me bleeding. I thought the yellow stone I was working was showing a layer of fine red streaks! Every time I dried the cab the red was gone!!

Sands the stuff I have has no name (free sample I got in the mail ages ago) but it is a veternarian wound dressing tape- I think horse stores (tack shops) sell it too- they use it to wrap the legs of horses!!! WOrks really great-
Now are you guys talking about a generic WD-40?

Now are you guys talking about a generic WD-40? Yikes, goodness NO! The WD-40 company does make a silicone spray, marketed under their 3-in1 line, but it is most definetly not the oily stuff we all know generically as WD-40. www.wd40.com/Brands/3in1pro.htmlSilicone spray lubricant leaves a dry whitish film so it doesn't collect dust or make a mess on things like the oily version does. |

Like Rally said. NO. WD-40 is not pure silicon, I think it has a solvent in it. Probably not good for leather.

VetWrap is the name of the self sticking tape. Comes in a variety of designer eye pleasing colors! Ed-super glue? What is is that you use to remove it from the dowel afterward? I haven't gotten a grinder yet, but that sure sounds way easier than wax!

Thanks John! Oh and Vetwrap is the stuff!!! I have just the plain white (it was a freebie) but my wife came home from giving blood and had some HOT PINK stuff on her arm- Works almost as good as the VetWrap!
