As the project states... I stood on the shoulders of giants before I took
the plunge. My article sums up all the research that was posted on the
site. I would do the backboard out of starboard if I were to do it again.

I spent about 2 months studying articles, schematics and photos from the
following really smart people:  Myron Welch (schematic) – My primary
Source  Chris Ashley (schematic)  Karl Mielenhausen  Jeff Hare  David
Swanson  Roy Kraft  Warren Updike
