Development: Cogen: Power to the people
We made a flat steel plate that enabled us to use existing mounting bolt holes on the engine to install a second alternator. This put the alternator pulley in the same plane with the pulley of the original alternator so we could run both with the same belts. We were able to make a pattern and cut this shape out of a 3/16 piece of steel stock using an abrasive blade on an ordinary skilsaw. The bolt holes were drilled in it using a 3/8 hand drill.
Building our powerplant with hand tools without a machine shop kept us true to the principles of 'guerrilla' manufacturing, that is, it could be built anywhere with very little capital investment.
