Actually, yes, limestone is always popular for building stone. Depends on how cheap it would be to produce from it. That Kansas orangey limestone would not sell well, I'd guess yours is that prettier Springfield/Ozarks limestone. I'm building a 2 strand diamond wire saw to cut slabs from boulders, I have been wondering how it would work on limestone. We have thick deposits of the Burlington limestone (Mississippian age - very fossiliferous) that erode to tall vertical bluffs along entrenched streams cutting down to the Missouri River. Many old limestone rock quarries around Columbia. They used to be our swimming holes back when I was a boy. Our farm sits atop the edge of a vertical 80-foot bluff of the Silver Fork Creek. Local Rebs are a bit touchy about people blowing up their landscape. Precision vertical sectioning might fly in places. Come spring, if your device is finished and portable, we could find you a test edge close to the road (200-300 feet) to practice on. Minimal bushwhacking.

Well, there is a shortage of limestone in these parts. Granite, on the other hand, is plentiful.

It's expensive in these parts, but all the "best" people have it on their floors or elsewhere. Very pretty for ground-level decks/patios. Some old public buildings are constructed of it. All the rest goes in the grave yards. Those mines have been operating for a long time. Not far from the biggest lead mine in the US. Missouri Red Granite. We are the limestone step children.

Thanks for the offer, it would be fun to meet you. But the device won't be very portable, it will be bolted to 8 inches of concrete and it will have about 600 pounds of 3 phase motor attached to it.

Yes, 50 hp. Actually I am using that one for a phase converter, the saw motor is 25 hp.

This seemed to be the cheaper way. A converter panel with start and run capacitors, and a good switch, was $700, and the motor I found for $250. Inverters made to handle 25 hp motors looked much higher than that. I think I can possibly run both motors on a 100 amp circuit, the converter motor doesn't draw much current, and because of the way the converter panel handles startups.

He is 100% correct. It is due to market factors. Ya could make more money growing soybeans. Go figure eh?

Actually, not a big deal. Soybean demand is a world market. Brazil at 115.5MMT production will continue to grow supply carryover.
