Organized Tool Box.jpg


Chuckle! I've got a special football-sized rock in my garden that I have used since the early '80's to work on my Opel. Mainly I used it to boost the lifting height of my jack. It helped me do my first engine and leaf spring swaps back in 1990, which I did with nothing more than a small car jack(which I also still have and use constantly) and that rock. It's indestructable and has 6" diameter carving marks in it from when it was quarried. It must have been at the bottom of a drill hole in a rock face that then had been dynamited to quarry the rocks. I think it's basalt.

It's even got RED paint on it!

That is an Opel rock and needs to be in a "Opel Museum" in Cal. or on E-Bay. :lmao:

That looks like a chunk of obsidian. So you used glass as a tool lol. I'm pretty sure it's not basalt I don't see any grains or textural characteristics of Basalt or it's intrusive brother Gabbro. Hmm Gabbro sounds a lot like Gordo and you are pretty intrusive too...

I had to Google that. Game of Thrones, you'd think I'd know that, being the Scifi Guy and all, but I didn't have a clue and I've never played or watched Game of Thrones. REALLY cool pictures of creepy folk came up. Neato!

That rock isn't as shiny as it looks, it's just wet. Whatever it's made from is so fine that particles or granules are indetectable. And it's the heaviest rock of it's size that I've ever encountered. It's like a hunk of lead. That's why I think it's basalt. I had heard that basalt is heavy and super hard and was formed by millions of years of microcritters breaking down the earth's original crust.

Here's a pic of the circular mark in it that I have always thought was from a core drill, it's not a fossil imprint:

It's definitely not basalt. Basalt is an igneous extrusive rock. Basalt is cooled lava think Hawaii. (The moon is also largely basaltic).
What you got there is sedimentary based on how it looks and its hardness. My vote is for chert (usually called flint). Chert is pure Silica basically and extremely hard plus it is sometimes black. It formed in the ocean by lots of dead things which means it is a biochemical rock. That sucker is a 7 on a scale of 1-10 of hardness.

Weird Tools in Your Box

Hey, let's change the direction of this thread and make it about weird, odd, non-tool tools that you might have in your box.

Do you use a spatula to do your body putty work?

A pancake batter swisher to unclog your tail pipe?

A garden hose as a mechanic's stethoscope?

I used to work in a tool and die-type machine shop with 30 guys, each with his own milling machine. Each one had a large, high, red rolling tool box next to their machine.

Each one of them had a pepper shaker in a prominent location at the top of their box.


Who of you guys will be the first to correctly guess why?



:yup:

Organized toolbox

I have never seen the process performed (normally drop parts off, and leave). But I have heard of a process called Magnafluxing where a magnetic powder is applied and then magnetized to cause cracks to show very clearly. Iwould guess that is what dalt shakers are used in shops.

I liked that magnafluxing idea..... but consider Rachel Ray, when cooking in her kitchen; everytime she adds a little salt to the recipe, she sprinkles a little salt in her hand and throws it over her right shoulder....for good luck. Old wives tale, I suppose, translated to the machinist's trade.

Or maybe it's some kind of graphite lubricant powder, used to cool & lubricate the work during lathe cutting operations......

pepper helps you "sneeze" out the hot shard of metal you just inhaled.

Probably not the answer but anyone that's done a lot of milling has had a shard of hot metal enter their nose before.

Volcanic rock in New Jersey?
Basalt (a volcanic rock) is actually found in certain parts of New Jersey. 200-300million years ago when the North American plate split from Africa a divergent boundary was formed (rift?) these divergent boundaries allow magma to reach the surface to replace the gap from the spreading continents. So if I remember geography correctly, Gordo is technically a few steps away from Africa if he is on the coast!
