Hi all. I know there's alot of folks who are using a dremel to shape and polish your stones, so I thought I'd share this simple to make leather disc. Just cut a disc from some scrap leather about 1-1.25" in diameter, poke a small hole in the center and attach it to the mandrel normally used for cut-off wheels. That's all there is to it. Use your favorite polish or diamond paste on the leather and polish away. The leather works so much better than the felt wheels or pads. A few pics. Ed

Xenas, more like belt leather, but about the thickness of purse leather. Micheals sells packages of scrap leather that's perfect for this.

Xenas, if you look at the pics, you'll see a shaft with a screw. All you do is poke a small hole in the leather, put the screw through the hole in the leather, and screw it into the end of the shaft. That's all there is to it. The screw holds the leather to the shaft. Once you turn on the Dremel, the disc flattens out from centrifigual force.

So are you using the regular Dremel or are you using the "Pencil" handpiece? Also, what are you guys holding onto the stone with? A dop stick? And are you starting with true rough or a tumbled stone after one of the stages?

Ed do you have any segestions on how you could cut out several disk of the same size so you could glue them together to make a cylinder about a half inch or so thick? Do you make violins or restore them? Thanks

Hey Duckbean. I would just stack the leather and glue them up first, then cut out the circles. As for the violin, I was referring to the violin lapel pin I carved out of jade for Tony's wife. There's a post of it in the photos section(on page 2) titled "The Green Violin" if you want to see it.

Hey Duckbean, I did build a classical guitar about a year ago. There's a pic of that in the "This is me" thread in the photro section.

It does have to be as close to round as you can make it so the dremel doesn't vibrate itself to pieces! Plus, be careful of the leather from Michaels as the black will sometimes have traces of polish still left on it and will discolor your stone. As I learned much to my disdain as I polished s beautiful piece of California Poppy. But, I worked it out after a few rounds with a piece of brown leather

Do you use the edge of the leather, or the flat part. If you use the flat part, wouldn't the top of the screw scratch up or chip the stone?

Karen, I use the mostly the edge, but as you push a little on the rock, the disc will flatten out and you're actually using the face of the disc.

Hi Duckbean
Making leather disks for dremel.
An eight inch length of steel pipe. With the inside diameter the size you want for the discs.
Cut off any threads , square up cut ends, and grind a bevel about 45 deg. on one end. Make it sharp!
Place leather on a length of wood and with the sharp end of the pipe down on the leather, pound out as many disks as needed.
Then take a pencil compass/divider to find center, mark and use a nail to make the screw hole.
You will need a longer screw, so a trip to the hardware store. Take the dremel attachment with you.
While there pick up one lock washer and two metal flat washers. Smaller than the leather disks with holes the the screw threads, not the screw head, fit thru to use as backing plates to compress the leather disks.
May want to consider removable loctite on threads prior to use to prevent screw from backing out.
Assemble from left to right in the following order, screw, lock washer, flat washer, leather disks, flat washer, small drop of removable loctite on threads, and dremel attachment.
Add or subtract leather disks to get a tight fit on the dremel attachment. Test run at slow speed and if needed run discs against some sand paper to true up if vibration is a problem.
Hope this helps.
Be Well
Dracco & Rockpup
