One of Bob’s favorite answers to some of our questions in class was the phrase – just enough.  Someone would ask “How much solder should I use?”  And Bob would answer “Well, you need just enough.”  Or the question would be raised “How long should the tab be?”  The answer – “Well, it needs to be just long enough.”

And we would all laugh/groan.  We knew what it meant.  It meant no one can give you a number, a formula.  It meant you need to try, gain experience, work with the materials, understand them, and you will come to learn how much is just enough.
