If it's typical granite (~.1 lb/ci) it's closer to 7K lbs, but still pretty heavy. I have a couple ex-CMM granite bases here, but the biggest is about 2/3 that one.

Whatever happens to the cross arms of old CMM’s? Have been looking for years...

I saw a guy buy one about this size for $50 at auction. Later he showed up with a single axle trailer and a come a long. Just blew his mind that solid rock could be that heavy, maybe moreso, why anyone would possibly make a table so heavy you couldn't move it without specialized equipment.

Without a current calibration, any granite surface plate/table/CMM base is just a lump of rock. With the current calibraion, they're vauable. Without, not so much. Sad, but true.

Uh-oh! There must be two of us, but I had a tandem axle that barely did it. Mine was complete with three axis readouts. In the paperwork that came with mine there was a receipt from a machinery dealer where the guy paid $50,000!

Yeah, seems that a lot of early CMM's got scrapped out when either software and controls became too out of date, or more automation and "smarts" was needs in the metrology lab. I've seen some pretty good size tables (like 10 x 6 foot, 20 inch thick) go for low bucks. I'd love something like that for mounting some micro-precision table-top mills to for isolation.

I was thinking a plate like that would make a bitchen patio table. Don't have to worry about it blowing away, getting stolen, insects, etc. Unfortunately tour looking at a good $2k to move it.
