End caps.
Tapped 8/32 hole in center cap. Drilled 1/16 hole (as shown in picture two) to pass thru end cap.
Stripped wire 1/2 inch and tinned. Positive cap.
Cut the 8/32 screw about 1/4 inch long. Used a dressing washer to hold the wire. Washer also is tapered allowing easy insert to positive battery box end.
Negative cap.
drilled 1/8 inch center hole for 1/8 x 14 in blind rivet. Riveted 1 inch fender washer to end cap. I cut a small groove on top side of end cap with the dremel so to lay the wire in (1/2 diameter of wire groove) so the washer would level with the end cap surface better and still maintain contact.
3/4 inch thin wall cut to 1 3/4 inch length with hole in center for input power wires. This holds the circuit.
