Challenge 3

That's the original surface of the moon, when Hermes created it, before the fall of the gods and randomization occurred.

Next?

'randomization occurred'

That would be the God Kaos, then?

Is it the gearbox selector detent mechanism from an old Ford Capri? Oh, no. Perhaps not. It isn't rusty enough.

A part of golf ball making...machine...just guessing......on second thoughts...nah..

It's a shame it isn't animated, really, like the rotating pictures on "Have I Got News For You!". CR4 readers could buzz-in with their answers!

It looks like my drill press table after an apprentice has used it

John.

ROFL!!!

Our shop had 3 just like it...LOL

The head of a golfing club. Perhaps what I belive is called a putting implement.

Or alternatively it's one of the inner faces of a table vise or vise-like apparatus.

Possibly used to hold golfing clubs for repair.

A rack for cooling freshly made glass marbles.

What a rare treat! That 'H' is a dead givaway! It's a Harrods commemrative thimble manufactured around the turn of the 20 century, possibly one of the last remaining specimens know to have survived the golden age of steam when, due to the lack of raw metal at the Harrods manufacturing plant, all items deemed 'luxury sowing items' were melted down to make collectable spoons!

Lower half of a lead casting die for old round bulletts.

no, too irregular, and too scratched.

The "H" is fir "H"ell if I know...

It's an optical illusion.

When I stare at it long enough, the detents and "H" become raised.

Or, it's a really bad first attempt at casting an egg tray..?

One answer that's correct so far folks!

So...what is it already? I've got good money riding on this you know.

Hurrah!!! I'm 2 for 3 on these challenges!!!

I'm great. Why isn't everyone else trying to be me?

The American Flag if Hitler would have come to rule! To easy!

I'm gonna go with the thimble

Halloway? golf club face.

OK.....

Right smack bang on the nail with post #11. Thank you Ladies and Gentlemen!

Another close up of something familiar.....

Teeth of a bastard file!

As a slight but yet significant enough for the win variation to Mr. Truman Brain's response, I'm going to go with "wood rasp".

Hmmm how about a cheese grater?

John.

This pattern is familiar enough to make me think I know what it is, but it's not familiar enough to make me remember it right away.

I doubt it is a file; they usually have diamond shaped teeth. I also doubt it is a cheese grater; the holes appear to be too close together, and you seldom see machining marks on cheese graters.

It does appear to be some kind of knurling, but on what?

OK, too easy for you lot.

One more really common item for you, 'cos I've found a totally horrible one lined up for next week!

It doesn't look like a chuck key, or is it??

The gear on the end is crude and doesn't look like its been made to drive anything critical... maybe to allow fingers to turn it?

Ohh I'm looking at it differently now, it could be a chuck key I guess.

John.

Yes its strange, but I was looking at that and the optical illusion made me think that the tapered 'gear' of the key was not tapered but eeerrrrmmmmm flat!

Let me say that again.... the brain thought that the edges of the tapered gear weren't edges but the troughs not the tops so it didn't look like it was tapered...

D'oh.......

Yeah, yeah....

I'll go with chuck key as well, but it also resembles the gears used in a hand-cranked popcorn popper.
