Nelson,
I used to work in an instrument shop, (industrial) that had all number of unimaginable equipment to be available.
Some of that apppenticeship has rubbed off I suppose, in how I like my shop set up, and tidy/things put away, (just need to educate the kids better!) and also in tool envy because I know what we had and what IS available and what I am making do with now, but really, there is no need for some stuff that guys get hooked up on.
Having gone through those links you posted I would say that that is someone who has access to a manufacturers workshop, either by working there or knows somebody, or likes to photoshop catalogue lists. But not a home handyman 1st.
There is no way a hobbyist would really need all that stuff. There is hundreds of thousands of dollars there.
Sure you might have some........ but really.....not all...........
Comments like "Used for quality assurance (QA) size measurements of many parts" tells me that this is not a hobby for him.
Or a 400+ component pin/plug gauge set for a home use?
Being able to "mic" every "thou" from zero to 6 inches? Yeah it would be nice to do. But on my home lathe making parts for a steam engine, or a mates bike?
And measuring to one hundred thousands of an inch, there is probably more than that much "slop" in my mag base and arms!
Do YOU supply a QC note with what you machine?
Sure, that stuff is out there, but not necessary, or even required for home use.
Cheers Phil
