I have mostly done flat surfaces in ebony, lots of sanding lol. When finished it is like glass. I used copper for all my support pieces in racks. I want something quick and easy so I can change heights as I change gear.
Polish is a capitonym, a word whose pronunciation changes when capitalized. You mentioned polishing earlier.
August and august is another example.I still don't understand putting a chip fab in a desert area. I understand you have the nearby river, but places further east (by a lot) where there is more moisture just seems to make more sense.
You want the fab to be near infrastructure. Water needs to be available, yes, but rivers are not required. Transportation infrastructure and an available workforce with the proper education levels is much more important - the Phoenix area has been Silicon-Desert for a long time. Plus fabs require extreme humidity controls and low humidity ambient conditions makes that easier. The biggest problem in the desert is dust control, so lots of money spent changing out HEPA filter media.
I understand why most things are built to be used by right-handed people, so it doesn't bother me. I'll make my own accommodations, even for tools which might be dangerous. I'm capable, I can do that.Left handed people were thought to be evil, we get our word sinister from it and many tools are made to favor right handed people. I do not agree with this by any means and it is certainly changing for the better now.
Is sinister unfair to the left-handed?
Sinister has an etymology that might seem a bit biased against the left-handed portion of the population, as this word, which has had naught but disagreeable meanings for over five hundred years now, comes from a Latin word of the same spelling that means “on the left side.” We find this root in other English words, such as the adjective sinistral (“left-handed”) and the adverb sinistrad (“toward the left side”). To make things even more unfair, the Latin word dexter (“on the right side”) has given rise to English words with largely positive meanings, such as dexterity and ambidextrous.
Bias against left-handed people is bias or design that is usually unfavorable against people who are left-handed. Part of this is due to design in the world which is often right-hand biased. Handwriting is one of the biggest sources of actual disadvantage for left-handed people, other than for those forced to work with certain machinery. About 90 percent of the world's population is right-handed,[1] so many common articles are designed for efficient use by right-handed people, and may be inconvenient, painful, or even dangerous for left-handed people to use. These may include school desks, kitchen implements, and tools ranging from simple scissors to hazardous machinery such as power saws.[2]
Beyond being inherently disadvantaged by a right-handed bias in the design of tools, left-handed people have been subjected to deliberate discrimination and discouragement. In certain societies, they may be considered unlucky or even malicious by the right-handed majority. Many languages still contain references to left-handedness to convey awkwardness, dishonesty, stupidity, or other undesirable qualities. In many societies, left-handed people were historically (and in some cases still are) forced as children to use their right hands for tasks which they would naturally perform with the left, such as eating or writing.[3] In the late 20th century, left-handedness became less stigmatized, and in many countries, particularly the Western world, left-handed children were no longer forced to switch to their right hand.
You are special, just like everybody else.
Okay, that makes more sense - didn't know about the humidity aspect. Wasn't referring to the river for barge transport more for makeup water. Agreed on education being important, my current employer has issues with that - locals require more training (not dumb, just not as educated trying to avoid a third rail here) and out-of-towners with kids don't want to move here.You want the fab to be near infrastructure.

-edit- And, of course, cheap land a low local taxes.
Fabs (and indeed really every aspect of the semi industry) use highly purified DI water for process-related functions. City water is used for some things, but mostly it's DI and fabs have large plants to make their own DI water from city water. So they don't really care where the water comes from as long as the city can make it available.
Yep, I am getting to learn about DI water for work - direct cooling of aluminum buswork to keep the eddy losses from 160MW, and RO makeup to the general cooling tower to keep the chlorides and other minerals low. Maybe I am colored by the steel industry, but we use millions of gallons a day even with multi stage (don't need the purity of multipass) RO to keep the cycles up, although for us 6 cycles is really good normally for evaporative systems.Fabs (and indeed really every aspect of the semi industry) use highly purified DI water for process-related functions.

-edit - re humidity controls. One droplet of water making its way into a chip fabrication machine can cause millions of dollars in lost revenue. It's a critical factor.
The steel industry is a completely different world. Your factories work at a macro level; mine work at the sub-micron level.
