What in the world is this?

[Truth]

I found it perfectly sphere 7” deep no rust marks at all and it is solid.

I found this many years ago.
I posted it on here someplace.
I was told it was a bearing from an old teeter-totter.
It is solid brass.

Thats a cool find I love things like that research is fun unless ya never figure out what it is then it can be whatever you want it to be lol

A2 I love this thing I hold in my hand all the time I just wish I knew what exactly it was

Looks like what I have it’s just feels like a metal from outer space

It’s just perfect

Interesting. An accurate weight and diameter would enable the density to be calculated, which might shed more light on what it's made from.

Milling ball is another possibility. It's not beat up, but then we don't know how much use it might have had.

Is it magnetic?

It’s not magnetic I want to say there’s not a scratch on this thing or a seam it’s crazy

Unobtanium!!!

Any UFO sightings in your area lately

Truth is there anyone around that could test its contents

I would love to know it’s just more fascinating than a grape shot to me

…Here is one from my sisters rock garden. I have more that I will track down…

If you mean 173.4 grammes as a weight and 42mm as a diameter, then the ball has a specific gravity of 4.17

Assuming it is metal, not hollow, and not a shell around a core of something else, that pretty much rules out it being made from anything other than: an alloy with a fair proportion of aluminium (which has an S.G. of 2.7); or an alloy with a high proportion of titanium (which has an S.G. of 4.52) and is commonly alloyed with small amounts of aluminium for engineering purposes.

From the lack of corrosion I would guess the latter, and that it’s some kind of bearing.

Red I’m just gonna have to come to the realization that I love a metal ball

Stainless steel milling ball IMO.

IT is highly unlikely it is for anything "artillery" wise.

Oh no doubt I’m just in love with this thing color, texture, weight it’s perfect and I wouldn’t want another one because it would make it less special

very cool find, interested to learn what it actually is

thats because its probably a machined peice. large ball bearing. or a ball from a check valve.

check valves work while water is rising(from a pump) and pushes the ball away while the water travels through a pipe. when the water stops flowing, the heavy round ball drops into a slot, preventing any backflow of water from coming back to the pump. the check valve is normally located just above the pump. inside the check valve sits a large ball.

under normal wear and tear of a check valve ball. the ball will appear to be pitted from cavitation and the hydraulics of water.

When I touch it I feel stronger

When I touch something else I can't mention here, I feel stronger too.

No pits but you might be right

I think I got you covered here . I have to get into my shop and check and if it is what I think it is I know why you feel stronger when you hold it.....gimme a few hours

Dont worry it will grow one day.
