As far as my electrical knowledge goes, I can wire a house, do minute repairs on automobiles. I really and truly know nothing about electronics and circuits and boards, so please forgive my crude electrical work, terminology and soldering skills.
Step 1: Grab some wood!
The saucer disk will be attached to the lathe using the worm drive screw. The cockpit will be mounted to the 3" face-plate.
Step 2: Mark center and prepare the blanks for the lathe
On the saucer section, drill a hole in the center of the blank all the way through. Use the proper size bit for your worm screw.
On the cockpit section mount the faceplate. I placed the faceplate centered on the blank and looked into each screw hole to alighn the drawn line center in the holes. then center punch them to create divots. I then pre-drilled the marks about 1/2" deep. then using 1" wood screws, install the face-plate to the blank.
