Sands, just use grout, or stucco and put the small pieces in. If you do go with a clamp, use either hard rubber, or lead in the jaws. Easier on the clamp. Your care package came. Beautiful work! How do you get them so flat, and the corners so sharp? Do you use a flat lap? I am going to send you some dumerite, and Royal Jade. I also have some real cool dumerite, real rare. The Royal jade is big bucks, so keep a good piece for your self. It has been estimated at 9$ a carat. If you have a flat lap, it is time you did some intarsia. You are definately up to it. Great work.

thanks doc i was hopeing they would get there fast --did you look at the slab grabber i posted it's so much faster then using plaster all ya do is when you cant cut any more you clamp that on the face of the rock you where just cutting and lock it in the saw vise with the rock clamped in it and start cutting from the other end of the rock i have been starting to buy more expensive rock i usta just throw the ends in a bucket but now some time i get a few more slices from something nice----i dont have a flat lap im hoping to make a deal with herm for that one she got from a friend im thinking i could use it for faceing bigger pieces--right now im useing 220 belt on a 8X3 inch drum and if you play with it just right they come out pretty good
i just ordered 8lb of spiderweb imperial jasper should get here this week--if its as nice as freda said ill make some and send them to ya,, i seen some on her site that looked real good

Cool. Wait untill you see what you can do with a flat lap! I use a 6" drum. I am really impressed with the results you get with a drum. With a flat lap, Intarsia!!! Lapidaryjournal.com has a tutorial on how to do it. I am also going to wrap one and send it to you. Might make a great gift for someone, or you might have a ball on Ebay.

John, I have seen your edges. They are good enough for intarsia. There is also no rule that says it has to be made just so. You could do it three sided, or five sided. The point is to join on a razor edge, then grind the joined pieced to a razor edge. The other trick the author did not write, is to use baking soda on the edges to be joined. Baking soda and CA also fill gaps so the joint does not need to be perfect. I do not know if epoxy could be used, the vibration of grinding might loosen the bond. You have razor edges freehand. Might have fun joining two pieces of stone and grinding them to a shape. I bet you could do it with the machines on hand.

John, Intarsia, as done on stone, is slicing stone and glueing it to another. Take a pentagonal shape. The center stone would be cut into a pentagram. Thin slices would than be glued to the outside of the original pentagram. As each slice is glued on, it is evened up with the outside edge of the last piece glued. Say your inside pentagram is 12mm. 6mm slices would be glued to the outside of the original 12mm. You would have five slices. Once these have been glued and trued to the last piece, the next piece is glued on. Once the pentagram is 6mm thicker, then five slices of the outer stone are glued on. Once those five are glued on, the outer shape is made, and the cab is polished. Badabing, Badaboom, Intarsia! I have now seen your work first hand. You can do it freehand. A lap makes it easier to do. Basically, all it would entail is adding a border to one of your stones, and then another border. All stone Intarsia is done with a central cut, and layers added to make a pattern. Some Intarsia is backed. Basically, that would be adding a slab backing with epoxy. That epoxy works real well for. I have done that with good success. I have had a small piece of bloodstone, and backed it with feldspar. Than I ground it into a cab. It came out real well. I suspece, the slice from the diamond wheel is the right thickness for the border to the center. Try one, you will see.

I have a suggestion for you. When you use a clamp like yours it will work much better and last a lot longer if you put a block of wood the same size or a tad thiunner then you slab in the vice at the opposite end. This will give you a much better grip on the rock your cutting with out having to tighten it as much. The block of wood doesn't have to fit in the small grooves it the end of the clamp.You can put it in just a tad and it will work just fine.

like those Jorgensen clamps that MichiganRocks posted not so long ago??
wood does seem to be the medium Lortone uses on the big saw vises.....
my little hole drilling vise is all aluminum. the vise that came with my saw had some sort of fiberboard pieces to hold the stone...

John, you can make one from 1"coreplast. That you can get from Home Depot. You can also bush the inside threads with valve adjusters. All you would have to do is replace the threaded rod. The threads on the valve adjusters on a Gm are 1/4 28. Put the valve adjuster on backwards and you have a round high point. Might give that a try untill you get another one. The valve adjusters can be found in any machine shop, or boneyard.

No Doc I'm not a machinest. I'm a self taught wannabe. We have a couple lathes,a Bridgeport milling mach,pretty good size drill press and a surface grinder. You'd be surprised what i've made on just these few machines.Nothing big but a for instance is a master lap,a few vises (different types and sizes,a lot of tumbler shafts,polisher/grinder shafts. The only problem is that I have to stay after work to use the machines so it may take me weeks to get anything that has to be precise done. But in most cases I can get things in a night or two. "Finding" the material is thr hardest thing to do!!If ya know what I mean?? LOL Tom ![;)](//storage.proboards.com/forum/images/smiley/wink.png)

Tom, I do not care if it takes years. My Raytech is still running. I am just looking to upgrade. The faceter is made with that white plastic used on counters. Most of the pieces are 1". I also like aluminum for faceters. You will find the faceter in Tips. Take a look. If you could do it, even if it takes years, Maybe we can work things out. All I have now is an hand drill, some mechanics tools, and jewelery tools like no one else. I am looking to get a speed increaser for my foredom next.
