In this shot, the turntable has been place face side up. I have placed the bottom plate and vertical band from my own unfinished radar on top of the radar to illustrated how everything fits together. The machined spinner post depicted in the photograph was made using the dimensions provided in Dave Painter's blueprints.

For my own radar, holes will be drilled into the vertical band to receive the peg of the machined spinner posts. The peg will have threads cut into it so that the spinner post can be held tightly and securely in place by a hidden nut on the inside of the radar. This is an ingenious concept invented by my brilliant machinist.
