Workbench with flush-mounted granite slab

[howlback]

Can anyone offer guidance on the best way to flush mount a tool grade granite slab into the 8’ x 30” workbench I am planning to build? I’m thinking of buying a 12” x 24” x 3” stone. Any advice is much appreciated

screw 4 of those to the bottom of the counter top.  install 4  -  6'' threaded all thread rod 

driill 1/2'' holes in 2 2x4s      this you can set the stone on and adjust the height/ level  of the stone with the nuts 

under the counter

 

add plywood above 2x4 .under granite

 

you need 4 nuts and  2 washers  per rod

Since I have a 6 inch jointer, . . . I can make boards any thickness I want.

I would build a "pocket" in the top of the work bench that the stone would slide down thru with maybe 1/8 of an inch clearance left/right and front/back.

That pocket would be the 3 inch deep, . . . depth of the stone, . . . and the bottom of it would be bolted solid up thru spacers that make the pocket 3 inches deep.

I would also leave a 1 inch or so hole at each end, . . . in the center of the stone, . . . just in case some day I need to push it up and out of the pocket.

May God bless,

Wait... so you're going to have a block that runs 12" across a 30" table?  Have you never seen an apron sink?

• Wait.. is the block right at 3" high?  Build your SOLID table, 2x4's on edge at 16" centers where the rock is (24" be fine for the rest) 3" shorter than you want.
• Place stone on table. 
• Build up rest of table to meet the rock.

Nope, nope.  I SIT to tool leather, and I SURE don't want a rock that size in my lap because it was HANGING from something
