Here's some pictures of my "Sealed Sled" Avbay.
Start with about 6 inches of 2.5 inch diameter plastic. I think its HDPE. Turn it to fit inside a 54mm Blue tube. Don't forget the o-ring grooves...
Then mill a flat bed for the altimeter.
Then flip it over and put a bed for the battery.
Put a hole for the rotary arming switch, and hole for battery wires.
Remove two screws from a terminal strip for mounting holes. I could not find any terminals in the small size that had mounting ears/tabs.
Put standoff screws in. Test fit O-ring.
Mount terminals, eyebolt and test fit altimeter. And she's mostly ready...
The rotary switch is in the mail...
I should fly it at Dairy Aire, near Fresno California next month.
The sled will be secured with 4 #6 screws though the airframe, the airframe will also have a 3/8 inch hole for the arming switch which also serves as the vent hole.
Over all not too bad for my first real project on the mill.
