The Lister Generator Project Page 2

A

I chose top mount my engine on a steel "I" Beam. This  massive part is 4" wide and 4" high. It weighs nearly 125 pounds. The beams are set on two pieces of 3" SQ tubing so I can get fork lift forks under it.



This part is the generator frame that will slide on the Beams upper surfaces. I placed some Teflon tape in the contact areas to make it easier to move. After the belt is on, tightening the 6 bolts will hold it securely.

The Generator is bolted up to the sliding frame.



Detail of how all the pieces fit together to hold the generator head to the frame. I used thicker steel on the next genset, 3/8" for the crossbar to stiffen up the generator head.

Detail of the spring tensioning mechanism. Hope it works (it didn't). Most of the design was the result of what pieces of steel I had laying around. I needed to buy some stuff. The entire cost for the frames and sub structures was $120.

Ready for the generator pulley and serpentine belt. This thing looks small in this picture. It's a huge massive machine weighing almost 2000 pounds.
Ok So the tensioning thing didn't work. After my friend, Charlie Bennett made me this beautiful serpentine pulley, we cranked it up and off the belt flew. After removing the springs and other changes, the threaded rods now hold the generator in firm position and belt is drum tight with excellent tracking. The generator is is temporarily sitting in it's new home in the corner of my hanger. The huge 10" steel "I" beams still need attaching tot he floor and the cooling system needs fabricating. I ran it briefly today with 1500 watts connected to it. The engine sound didn't even change with this small load. Using a KILL-A-WATT, I set the engine RPM to make 60 cycle (ABOUT 837 rpm) and the volts were steady at 250.

IT RUNS   ON TO PAGE 3!
