[Elecraft] OT: High school drafting class, ~1975

[w2bvh]

I didn't get to do a drafting course until college. It was taught by the 
dean (guess any prof who had to get us to understand solid state 
physics  was "too good" to teach drafting).. I still fondly remember 
doing some sheet metal layout and having such an oddly shaped piece in 
the flat mapping so well to the intended shape in 3D. Didn't help at all 
with EE, but fun!

73 & stay safe

We invented things to draw that weren't real, but looked like they should be. Did all the math by hand -- on a slide rule, if necessary. Day-dreamed about what we might one day build.

Carefully documenting it took several sheets of 4-squares-per-inch grid paper, which may still be in my cellar, beneath a lifetime of such drawings. With the schematic, I took a lot of pride in making the circuits look well-organized, as if that would somehow improve my odds. On the PC board, I drew large traces and pads with the etch-resist pen, as if that would somehow appease the electrons.
