Very interesting. Two Things: 1.) Never seen quarts(or even gallons) moving CCW - or was it “quartz"?. Lol 2.) I guess we better move to Egypt for faster aging, and Australia to get younger. Thanks for the great info. Jack #4348

Jack,
Clocks? I have had my hands in clocks for 35+ years. I have put the wrong motors in clocks and they have run backwards for a short time. I have also seen quarts movements that were made to run backwards.
You may enjoy the article about clock wise.

Pretty much everyone knows that if you’re asked to pass something clockwise around a table, you hand it to the person on your left because that is the same direction that the hands of a clock move. But what you may not know is that this standard direction is a function not only of timekeeping, but the Earth’s rotation and the happy accident that much of human civilization evolved in the Northern Hemisphere.
If you could look directly at the North Pole from space, it would appear to spin counterclockwise. Given that spin, when a stick is placed in the ground parallel to the Earth’s axis in, say, Egypt, the shadow cast by the stick as the Sun moves across the sky will move in a clockwise direction (notably, a similarly placed stick in Australia would cast a shadow that moves counterclockwise).
As far back as when the ancient Egyptians and Babylonians were fashioning their first shadow clocks (~3,500 BC), the measurement of time moved in a clockwise direction. Even as more precise timekeeping methods came about, sundials (which began in earnest around 1,500 BC) remained popular throughout the middle ages and beyond, given their simplicity of construction and relative reliability. (In fact, early mechanical clocks were often regularly calibrated to nearby sundials.)
Wells_cathedral_clock_dial One of the earliest mechanical clocks, the Wells Cathedral Clock in Somerset, was wound by hand from its installation in the late 14th century to 2010, when an electric motor was installed, saving someone having to climb the steps and wind it (~800 revolutions per winding) three times per week.
So, when mechanical clocks were introduced in Europe in the 14th century, their inventors were quite familiar with sundials and the clockwise direction that their shadows moved and marked time. Accordingly, by the end of that century when even cathedral clocks were sporting clock faces, they were made in imitation of their sundial forbears, which included hands that moved in a clockwise direction.
Notably, the word clockwise with its present meaning did not appear in English until the 1870s, with counterclockwise also dating to that decade.
The use of wise to mean a way of proceeding dates back to Old English. Clock isn’t nearly so old, and dates to the invention of our modern mechanical clocks (14th century). It is thought to come from either clokke (Middle Dutch), cloque (Old North French) or clocca (Medieval Latin) which all meant bell. Some of the earliest mechanical clocks were simply designed to strike a bell at set intervals, perhaps to announce prayer times or the like, or simply ring on the hour, with these early clocks not necessarily having any faces. And if you’re curious, before they were called “clocks,” these early mechanical clocks were called horologia, from the Greek for “hour” (ὡρα) and “to tell” (λέγειν).
Thanks,
Larry

Stephan - thanks for more input, but did you mean the bearings are cooled with oil? I had an XKE - 64 - it ran a wee bit hot - needed an oil cooler. Age - the great equalizer. We fight it, but it always wins out - still looking for that watch/clock that runs CCW. But then again, I’m glad to have made it this far, unfortunately, a lot don’t. Jack #4348

Good morning Jack. Years ago my dad explained to me that oil is the primary heat transfer agent in an engine. It is the closest to the things that get hot. OK - the heads are filled with water, which gets pretty hot, but the bearings, the pistons, the rings all get cooled with water.
Just bought a SPC Daytona - with a 351 Dart block bored and stroked to 427. It came with an oil temperature gauge. Yup, oil runs 20 or 30 degrees F hotter. The Daytona also has an oil-cooler built into the radiator.
I also have a '70 XKE. I added a factory oil cooler that I was lucky enough to snap up when a Jag aftermarket outfit found the cooler at a dealership they bought out. Overall - makes the engine just plain bulletproof when it comes to cooling.
So, sounds like I am a big fan of oil coolers, eh? But, really, no. Modern multi-vis oils significantly extend the effectiveness of oils - I would, and do watch the water temperature in our Pantera, but honestly, I give no thoughts to the oil temperature. But then, as with you, I am probably on the old-man side of my driving. I don't track my cars but I do put miles on them.
Thoughts of an old man contemplating cleaning up a car for a show tonight.

Just wanted to thank everyone for their input on oil temperatures. The List and the participants are unique and indispensable, in my book. The thoughts and ideas are just great. In my case, the first thing I need is an oil temp gauge to see if it’s even an issue - so logical. I judge from my driving habits (old-man-style driving) I may not have to worry about it. But I do. I guess it’s a “Pantera-thing” to drive down the road in “readiness” for the next issue, because it WILL be there - Just a matter of time. "Upgrading Unlimited” - I love it. I get so “educated by The List. It’s like asking the workshop manual questions, and getting answers. #4348 _______________________________________________
