'''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.

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.
