Oh, that color! Looks like maybe some of the matrix material is even silicified? Collected or purchased?
My Buddy Rodney recently mined it, I am slabbing it up for him to take to the PowWow. He brought over three large boulders, so lots of cutting ahead of me.
That is really cool! Thanks for taking the time to post this, Tim.
Is it always open like that? Is oil mist an issue?
Oil mist is an issue!!! I would not use this saw in a closed room without some major shielding. I don't intend to keep the saw, it was just a fun restore, let the next future owner worry about it.
The cast iron construction also accounts for the early death of some machines. I had one that I traded to a friend and he promptly broke part of the vice and as is commonly known welding that stuff is not easy.
It's funny you mention the potential breakage. I was very nervous sending the parts out to get powder coated for that reason, I only sent the parts that I could not properly sand blast myself.
and arbor that oscillates up about 1/4 inch about every second to speed up the cut.
Any further explanation on the mechanics of this? Does is jog back/forth ie, one edge of the blade is doing the bulk of the cutting?
I tried to capture the oscillation in the video, but it did not show it well. I will take a couple of vid's when I get home from work.
But, when cutting the blade will be in a stationary position, then about once a second the blade will move up about 1/4", then back to the stationary position, the pivot point is about 8" behind the arbor. Very similar to how you would cut a plank with a hand/chain saw, changing the angle of the blade to cut a smaller surface area.
This was a fun project, it is a well engineered machine with a oil recirculating pump and arbor that oscillates up about 1/4 inch about every second to speed up the cut. I need to find a lapidary museum for it, it is such a novelty saw.

I have decided to go with recirculating, the setup looks OEM, not sure if it was an option or not, but it is well installed. My only concern is the odor of a 5 gal bucket of oil, i guess i can always rig up a lid.

rocknrob: We could use more people like that now for sure. Or if being a nice person is too hard, just leave some tumbled agates around places where kids play for them to find!
