These are some images from work over the weekend.  We are trying to use sprockets to increase the RPM and power output from the alternator.

Attaching a wood frame to the steel armature so that the bearings/shafts can be mounted for the sprockets.

Finished wood frame.

Attaching bearings and shafts with different size sprockets to gear up for higher RPM. 

Alignment of sprockets with central shaft, secondary shaft and alternator
