If it had not been for Mr. Voelker, this chair would probably be at version 7 by now. We had already started with a Toyota-style effort of continuous improvement.
As for tools, the trick is to ALWAYS read the manual. You don't need formal training and while it helps to watch someone skilled, there is NO substitute for knowing what the guys who made the tool think important.
And don't worry if no one else in the family is good with tools. My father was a preacher who could be confused by a screwdriver, yet both my brother and I are very graceful around tools and still have all our fingers. "Remember the I35W bridge--who needs terrorists when there are Republicans"
For me it was probably a case of getting discouraged rather than not having the right influences. And I suppose with all these people around who could do the stuff I never really worried too much about it. It may be one of those things where I WISHED I could do something, but never worked hard enough at acquiring the basic skill set to actually set about the DOING.
The only advantage to beeing shorter than most, is that at some point all the population is or was your size, and they don't make stuff that just flat won't work for you (there are exceptions, if you are short enough I guess). My friend who was 6'6 and got there early, just didn't fit into some things, especially 40 yrs ago, when that was truly exceptional height.
