'''NOTE:''' Completely assemble the structural components of the of the AV bay, with the mounting rack, bulkheads, and coupler put clamped together, and all of the holes on the bulkheads lined up ''before'' epoxying anything, to make sure that every piece is oreiented correctly, then disassemble and epoxy. This is easier than you might think to mess up.

=Mounting Avionics=
'''NOTE:''' The specific electronics used in an AV bay often differ, so there is no single best way to mount everything. Before drilling holes or permanently attaching anything, lay out all of the components and make sure that you have enough room. '''Remember that there are all threads running on each side of the mounting rack, so make sure there is space for them when mounting electronics.''' Also, remember that wires are actually a thing, so plan space for them. Think about how you will close up the AV bay with wires attached to the top and bottom bulk head. ''Think everything through before mounting stuff.''
===Altimeter===
While each type of Altimeter are mounted slightly differently, they should all be mounted with screws and spacers, or standoffs. To get the correct hole pattern on the mounting rack, place the altimeter on the mounting rack in the correct position, mark where the screw holes in the altimeter PCB are, and drill them out. The holes should be sized such that the screws you are using can thread into the duron. Make sure that you use spacers, as shown in the diagram, between the altimeter and the mounting rack. Otherwise, the barometer may be pressed against the duron and not take accurate readings.
===Batteries===
Mounting the 9 volt batteries is relatively simple. Use snap on connectors to connect wires to the batteries. Both batteries are typically mounted on the same side. Use double sided foam type or PCB mounting tape to attach the battery to the mounting rack, then clamp the batteries in place using zip ties that run through the horizontal slots in the mounting racks.
===Pin Switch===
The pin switch is used to keep all avionics in the rocket powered down until the rocket is on the pad an ready for launch.
