Assembly Instructions

Instructions
The current is carried by the main shaft which is split in the upper lucite block. Sometimes it is necessary to work the upper bearing to get it to make good electrical contact (apparently it oxidizes and provides enough insulation to stop the current flow). Note that a series key is built into the circuit. ​
