Moving on. I filed down one side of a pair of pre ’82, real copper, pennies to make two contact plates for the cell. Both have a spring soldered to one side and a wire soldered in place as well. I neglected to take pictures of one of them before I installed it in the cell hole. :person_facepalming: I did photograph the other though. I’m planning on using a flat top Panasonic 18650B cell. The springs will also allow a button top to be used. The driver that is planned has LVP so I’m not thinking of a protected cell at all.
The disc below has the wire through a hole from one side.
The side with the spring in place. Yes, black = negative.
The first disc I made I glued in place before thinking of the camera. Darn. The red arrow points to the contact disc with the spring in place. Kinda hard to get a photo shooting down the cell hole.
This image from the bottom access hole view shows the edge of the copper disc with the + wire. The darkened spot is the result of the CA glue.
The switch is a small Omten 1288 reverse clicky. It needs to be mounted on the end of a dowel rod (wood) that the first item I made (the copper cap drilled for a switch boot) will fit over. The Omten 1288 is just a little smaller than the dowel rod. I needed to drill holes through the dowel to run the wiring. Some holes at an angle…
Here’s looking at the upper end with a tweezer through one hole…
This is the view of the bottom end. The slot on the circumference is a keyway that will slide over the protruding edge of the copper disc, in the access hole.
Here’s a couple of pre assembly shots showing the switch mount with wires running through the inner holes. That will slip into the hole in the body of the light.
Also note the rounded edges of the block. Those were done with a 3/8” roundover bit in the router. I sanded the block and gave it a couple of coats of clear acrylic finish. The final finish coats will be applied when it is complete.Right now I simply wanted to keep the wood clean and keep the orange color from wood dust from getting on me.
Lastly for today, another shot showing the + end copper disc. A little easier to see than in the other shots.
