I was cleaning off the work bench in the garage last week and found this piece of Laguna lace agate. It was an end cut that I forgot about. Can't have a contest with just toe entry's

If it isn't white enough let me know, I will cut a piece and polish it to see how it looks and if it's white for what you want I can send it to you

I can trade you somthing ? I have a couple of different oynx or lapis Nevada (mostly green with some pink, I may try to make a trip back to the mine and was going to look for more pink )
Planning on a trip to wonder stone mountian and over the hill for some green serpentine.

Are you looking for a piece of white quartze? I have a few prices that I was going to cut up and make a doublet with black jade to try carving somthing with a white background
Here is a picture it came from the snakeskin agate area near Austen Nevada it looks more like jasper because I cannot see any light thru it

Ok Don, this friend has been doing lapidary and jewelry since he was a kid and likes the bump wheels. He is in in his early 60's
 He is going to give me lessons on lost wax casting
I will see what Gary says. I have an 8" I was going to give him
7  Lapidary the Internet and You / Moderator, Michael Hoover / Shop and Swap / Re: Bump Wheels on: April 21, 2016, 11:01:49 am
6" or 8". A friend of mine is looking for a couple. He would prefer the. 6" wheels but could use the 8"

Sandsave. How big is the queen stone. I would like to get some of the to make a sphere out of but it may be a little far for a field trip?. Is it a rhyolite? Going to try and go out to wonder stone mountian in a couple of weeks and get a few pieces big enough to make spheres out of

That's a pretty one . Do you know if the oynx came from oynx springs in the panimint mountian near Death Valley. I went there a couple of years ago and collected 800 lbs and split it with a friend. We wanted to go back but the mine owner didn't want to do anouther fee dig right now. It is real cool rock easy to work and takes a great polish. Don't leave it in the sun it will turn white. I have a big piece setting by the 24" saw to cut for a sphere. Should get one over 6"
I think that I have made six spheres form 3" to 6" from that onyx
Here is a labradorite I just finished and an agate from a rock that I stole from a friends rock collection. I may give if back to her

Ok I have a few minutes   The rock that I have cut 6" spheres from have weighed 50lb or more. I spent $300.00 on the sodalite rock, but I got a lot of slabbing material from it. The price of the rock can vary from $1.00 a lb to ?  I am able to collect a lot of rock where I live.

 You can make a sphere by hand but it is a lot of work. if you search the internet you can find better instructions than I can Give you.you will need some kind of motor drive (100 to 200rpm is best)  with a spindle that you can attach a 3/4' pipe thread male adapter and a steel pipe adapter from 2" to 3/4" , a brass 2" pipe 90 and a short piece of pipe for a handle. Cut a cube of rock (3" ?) and than cut off all the corners and hand grind it to a some what round preform. Start with 90 grit wet slurry and put the preform between the two pipe fittings and start grinding, rocking the pipe fitting around to keep the preform rocking and rolling always in motion keep it wet and add grit as needed, when round clean up everything one piece of grit will ruin everything if there are any cracks or pores you will have to clean the grit out of the rock,  progress thru the grits always cleaning between grits. Polish you can attach felt or some other material to hold the polish.
 a softer rock like serpentine or travertine oynx  would be easier to do.  or spend a bunch of money on a sphere machine Or You can buy a sphere from someone that makes them

When u get a few minutes I will tell you how you can make them by hand. They don't have to be big. I have done a lot of ones under 3".

I should put it on eBay. Mybe I can get my $20.00 back?
Naw I don't think I will stick someone else with it. I bought a piece of jade off of eBay one time and it turned out to be serpentine. I should of complained and returned it
It did make a nice 3" sphere

The hardness of the stone will help. If you have a tumbler you can them in it and polish them. if they are hard enough.

What did you pay? want to buy some more? LOL
I bought a milk crate over 1/2 full at an estate sale and got the same results cutting it.
I think I paid $20.00 for it. was thinking about trying to heat treat it. But haven't wanted to burn up that much energy for a test run.

the Sodalite came from Africa the lighter blue that I have came from Barzil. Do you know where Yours came from.
I have another piece from africa that is very dark, the cabs I have done look almost black in till you get bright light on them. I didn't do a sphere out of it, it cost me a lot more $ per lb. I only slabbed half of it I could still cut a 4" ball out of it.
