Hi all:

I'm a newbie and really glad I found this site.  The works by you members are beautiful and inspiring.  I have been making spheres out of 15/8" geological drill core.  I had shown some to an artist friend and he said 'Can you make an egg'?...so I am wondering what kind of machine can I make to do same?  We have a lot of natural soapstone up here also so maybe that would be best to start experimenting with?
Thanks for any and all suggestions on this

Cheers

Roger

I think that they use a lapidary rock lathe to make eggs. Maybe you can put somthing together with a saw blade?

Thanks Jhon P

I do have a homemade spindle attachment on the end of my arbor and can screw the 1.625" diamond core bits onto same.  Was also thinking of using two separate bits, some chopped fiberglass and a frozen egg to make a mold (two halves)...then line (epoxy) the inside of the mold(s) with (maybe 50 grit) segments of polishing pads.

Maybe this would work for the soft soapstone(?)  I'll check further into the lathe setup.

Cheers

I would think that a full enclosure sanding jig would make it impossible to flush the dust.  Clogged abrasive doesn't cut worth a darn.  How about using an angle grinder with diamond cup or disc to cut on a spinning arbor?
