Can anyone give me any pointers on tumbling limestone with fossils embedded. There are three types on my place, I can only identify them by color as that is the only thing I know about them. There is a red colored one, the color of a Dr. Pepper label, a yellow orange one the color of the stripe above (post message) and the usual white color. All are relatively soft, but filled with all sorts of little shells, snails etc. How do I tumble them without tumbling them away?

You do not. The tumbling will erode almost all of the detail worth keeping. With those stones, they should be ground, sanded, and polished. Also very easy to do, and worth learning.

Thank you, the limestone is removed from tumbler after three days, I will do some grinding and polish.
I am obviously very new at this, but it is something I have wanted to do for more than 40 years. I got my first 33b in September and it has been running 24 hrs a day since! A 12 pounder followed in October.
The first batches in the 33b turned out well but the first polish stage in the 12 lbr polished for two weeks to no avail. Thanks to this forum, I realized that no matter how many times I washed the already used leather strips, they would never come clean from previous grit and they were contaminating my polish stage.
I had to start over and the batch is doing beautifully. I call them my pasture jewels. Thanks again. I know I will be back to ask questions, this site rocks. ;D

Take a look at the thread on grinding machines. You might find some interesting things.
