pendulum and putting it together

I then Fitted the lights to the frame. last main part to do was the pendulum. I had a steel ball lathed on the CNC lathe to act as the weight and I used the manual lathe to make a tip for the wight. I had a hole drilled into the centre to fit an 8 mm aluminium tube. I struggled for a while on how to fix the pendulum to the frame and ended up using a piece of bent wire that both ended the pipe well by tapering it off. Inside the pipe there is a copper wire that connects to the positive wire from the frame and brushes against the copper rings on the switch

ALMOST DONE

The last few things I needed to do was to add quarter circles to the bottom of the light housing and put the acrylic cover on top. I chose frosted acrylic to diffuse the light from the strip leds.
