Brief Description:  Andair Fuel Valve-4

Had a productive evening-at least in my mind. Screwed down the mid cabin cover and back drilled thru the mounting angles for the three mounting holes on the fuel valve. Stuck a mirror underneath the cabin cover so I could see where to drill with the angle drill. Holes came out ok. Removed the cabin cover and rear angle. I used the Andair trim ring to trace the center hole for the fuel valve stem and housing. Fiddled around till I got the approx. center of the 1” hole. Drilled a pilot hole, then used a step drill up to ¾”. Next I switched to a sanding drum in the dremel and finally a small scotchbrite wheel in the die grinder. Round and round and round until the fuel valve fit perfectly. There is a gap between the 2 mounting angles and the cabin cover, so I made some spacers from .063 stock. I will rivet these spacers to the angles with a couple of c/s NAS rivets-this will allow the cover to lay flat on the angles where the trim ring screws to the valve body. Match drilled the spacers to the angles, c/s, cleaned up and primed.
