What is it?

[Skeet 028]

That is a type of gasket between the top and bottom internal body of a 1959 Chevy slip/slide turboglide transmission....

Actually sounded like I really knew didn't it??

Early prototype for whack-a-mole game?

I dug down a few inches in the holes and just got more dirt. Don't think any concrete under the plate.

In that case, I think that it's a homemade grate for some type of dry well that's now been filled in.

Looks like a test plate for different sizes of carbide hole saws and straight shank carbide drills.
Things like how many can I make, actually diameter and smoothness of the cut and any damage to the carbide.
A company that makes these drills has several laying around.
They have been putting holes in hard things since 1947.

It does look like something you'd see laying around a Tin Knocker's apprenticeship shop? His first project so he saved it. I suppose it's stainless steel. CalifEd seems to be onto it. Also, too much time, too many beers, and some leftover concrete.
It's flat to the ground, but I know sure as pie that I'd mess up my lawnmower blade on it!

 

[DARE]

To give you some scale; the plate measures 3.5" X 7.5" and the concrete surround measures 10" X 14"

Mohel template.

These are some shims/discs I was punching out last week.
Really looks similar.

It looks like a plate embedded in the concrete. I'm guessing beer had something to do with the placement.

 

[Breakaway500]

Leftover piece of marine grade stainless steel that someone decided to not "waste" is my guess..

Are the holes in the plate filled with concrete - or is there a void in the concrete underneath the holes?

Just spit-balling here, but I'm thinking that it could be intended to be used to scrape the mud off the bottom of your shoes before you go into the house - maybe?

My mom lives in southern Arizona where they have some REALLY sticky mud that cakes on the bottom of your shoes, and just about everybody has some kind of home-made "shoe scraper" device located fairly close to the entrance of their abode.

Other than that, I got nuthin'

You ever stepped in any Alabama red clay? Now THAT is sticky!!!
