1dave, I run across broken geodes of this material that can not be clamped in the 18 inch saw without risk of cracking. They have thin wall thickness. Especially after the saw has started to cut some of the geode away and the vise pressure crushes is it during the cut, risking a bent saw blade. That geode/thunder egg holder of yours may solve this problem. What do you think ? These geodes are not always round...

Beautiful tumbles, the color is amazing. Could sell those a dollar or two a piece, maybe more.

Ten dollars a piece? I'm cheap myself. They do look great.

There would tend to be the same amount of material on each side of the blade if it did break, lessening the possibility of damaging the blade.

Have you laid a slab flat in and cut it 1dave ?

Have you laid a slab flat in and cut it 1dave ? No, but just for you I will give it a try next time I'm in the shop. Monday going rockhounding, Tuesday back to painting my cargo container (that red roof was rusting badly and got HOT under the summer sun, so I covered it with Hammerite smooth white that encapsulates the rust!) Years ago I could have done the roof in a couple of hours. That took me three days! Now working on the ends and sides. Perhaps Wednesday?

OK 1dave. Make sure the slab does not flip as the blade starts to touch it. That rig may be cat's meow for cutting delicate thin walled Geodes. White paint should cool things down. Hot tin roof effect. Rusty metal sure collects heat. Watch out working on the ladder.

Hot tin roof effect. Rusty metal sure collects heat. Watch out working on the ladder. I don't think it can flip with the blade pressure being down. Perhaps if I had cut the sides on 10 o, but I just lifted the back of the saw - lazy man's fix. I plan on selecting a fractured slab, make it difficult. Probably tomorrow after the rock trip. We usually quit about 1 PM and call it a day, take the group out to lunch at the Chinese Buffet.

A 1/2 day rock trip in Utah ? Unthinkable. We already have more rocks than we will ever do anything with. Getting out is the BIG DEAL! We went to "Gee" will post in Trips when I get back from town. I grabbed three slabs so it had to hold all of them secure and tossed them in my jig just for you. I forgot it couldn't cut beyond 3 1/4" and when it hit the end of the table, had to stop and take it out. I put the top slab back in first, then finished cutting. It broke on a fracture, but the cut continued as if it hadn't happened. The jig is a winner with slabs.

So the tumbling guys could mince up some slabs in a hurry with that rig. It doesn't get much easier than that 1dave. Kinda goes against your instinct to not have a rock clamped, but you have a rig that will do it. Guess you need a pack mule out your way, steep hills/rocky terrain. A back pack full of rocks is a humbler. Saw oil had a discussion with the white paint.

Saw oil had a discussion with the white paint. *snort* looks like it needed a primer before the paint.
