Built the airspeed bezel yesterday. I had to cut my own acrylic for the glass as McMaster-Carr does't sell anything except in full inches for acrylic disks.
The raised ring for the airspeed bugs is a piece of 14 ga. insulated solid core wire, and the knob is from a very old, no longer used TASCAM mixer.
The hole to the lower left will be filled since I stll haven't found out what would have been installed there in a 727. The hole underneath is for the RMI.
Still have the RMI, radar altimeter, vertical speed, and accesory bezel to complete on the main panel.
