That documents the whole building from start to finish, including the 3d computer controlled router/plasmacutter we built in order to fabricate all the parts.
The whole thing including making the tools took about a year and half.
A single picture of the completed machine is here:
It's a variable pitch 3 blader with a 'drum' type rotor that holds 18 2x1x.5" neos. Total power about 2000 Watts, design power was 2.5 KW so not perfect but still pretty good.
