Heck, we're all human here, and because we are, the discussion can go afield
easily.

Candidly, those seem to be self-removing. Either because they make a mistake
that is at least highly educational and go else where for easier pickins, or
find the subject too complex to fully grok. It is a fairly large step from
high school electricity to the field of cnc machining as you are finding out
I think. Not insurmountable for those that want to learn, and I congratulate
those that are willing to put forth the effort, and that includes you.

Generally speaking, we aren't saddled with quite that onerous an inspection
here in most states, which is a good thing IMO. Here in WV all they look at
is the safety stuff, lights, tires & brakes. And they didn't seem to care
that the headlight had a completely illegal 140/100 bulb halogen in it. I
like to see the deer I'm gonna hit, before I hit it. :) I have more than
once replaced the scratched or cracked 1/8" or 3/16" thick plexi in a
WindJammer style fairing with a similar thickness of Lexan, but the molding
to a cylindrical curve is a certified bitch with that stuff. As is drilling
the holes to mount it, needs VERY sharp drills. Bring money too... But man,
is that ever tough stuff. A .065" thick panel I used for garage windows (and
swarf shield between my mill and the computer) claims it can stop a 22 long
rifle bullet. But as a WindJammer windshield, that thickness would fold over
in your face at 60k/h.
