Checking flatness!

Hello again!

My wife wanted me to take various old furniture taking up too much room on the other side of our duplex (currently a storage facility)to the local Goodwill.

We've got these.....

[ATTACH]20866[/ATTACH]

Measures 29" dia x 3/4" thick 1 item

[ATTACH]20867[/ATTACH]
Measures 18" dia x 3/4" thick 2 items

They appear to be granite and are very heavy.

Suddenly my gears started turning.....

Checked them for flatness with my Snap-On straight edge bar of steel used for checking cylinder head warpage.

These stones are dead flat.

Immediate thoughts of usage that come to mind:

Honing chisels and straight blades with sheets of varying grit paper glued onto the stone with removable adhesives. Obviously using honing guides for proper angle of course.
Really, any edge or surface, wood or metal could be sanded flat with the proper medium attached to the stone.

Checking flatness on anything really.

It could be easily stored on edge( take up less room) or even incorporated into a bench top!

The smaller one's support could be notched to fit across the way tubes and clamped in place or just temporarily placed on a bench top. They're heavy enough not to move at all while honing or sanding.

Whattya all think about some of these ideas?? Reasonable or Ridiculous??

Yea, already thought of the idea of making a miniature flour mill.

Don't bother going there!

Good ideas !
But if you bring furniture like that to a Goodwill store, I wish it was in my area, I would go and get them right away.
Those are great looking tables and stone like that cost a pretty penny actually more pennies than that.

On a bench or inlayed in a bench is an excelent idea.

Across the way tubes not so good.

For years now I have purchased 12x12 marble/granite squares at Lowe's or Home Depot because they are dead flat. I will glue a sheet of wet/dry sand paper to the surface to hone or flatten blades or even planes I find in flee markets. Glass squares are also dead flat and great to use with value grinding compound to flatten tools.

I just purchased a granite slab for a hutch I made. About 20"x50" -$300. It isn't cheap especially when you pay additional for the edge treatment.

Maybe with that 29" dia stone, one could flatten the main and extension tables with say....220 grit?

Not to mention...circular saw tables, jigsaw table, jointer surfaces, fences, or surface sand assembled boxes or other items perfectly flat that are too large for the disc sander or belt sander, etc.

Also good for rolling out dough on.

I see a really nice sharpening center in your future. And that is some beautiful stone!
