Screw some carriage bolts into the tapped holes on the primary face of the 1-2-3 block. Making basically a table out of a steel block.

I'm still at a loss how one would use such a thing.

A machinist jack is used to support overhanging work and in tricky mill setups. Unless you do some funky work or setups they are rarely used, but they do come in VERY handy!

I think the Starrett jacks can hold 1000 pounds a piece, so they can really help in setups bring strong and stout.
 
I bought a bunch of stuff from an old machinist guy, in on of the boxes was some, machinist jacks, and ...........brake adjusters for drum style brakes.

A coupler nut with a suitably long bolt makes a very functional quick and dirty jack. I use them all the time in the saw and on the mill.
Just grind off the raised lettering on the head of the bolt and you're good to go.
