Integrate Piston Cup Assembly
Screw diaphragm into Cup with four grub screws using a 7/64 hex wrench
Integrate the T-fitting into the piston's inlet port (top side) with 2x plugs and firebolts2x FireBolts, a pair on each side. Make sure the T bar is horizontal with respect to the end plate.

Screw the Payload bulkhead into the top of the piston using 4x 1/4-28 bolts that are 3/8ths inches long. You need a 3/16ths wrenchhex key.
Insert Avionics Bay
Insert detailed AV Bay procedure here
Put the coupler over the piston and screw in the lower bulkhead. The switchband should be nearest to the Payload bulkhead.
The milled face should be internal to the Avionics Bay.
Put a nut on one side of the piston rod and screw the piston fully into the diaphragm.
Put a nut on the other side of the diaphragm and counter torque the nuts.
Adjust the piston height so that the piston-cup assembly with bulkheads reach a total of 28 inches tall. It should actually be slightly less, but this is adjusted by trial and error later on in integration.
Put the body tube on over the lower half of the assembly. “Struggle with clocking” - Jakob
Screw in four ½” 8-32 screws.
Screw in the nosecone with the right clocking using four ⅜” 8-32 screws.
Put the mission package assembly on the fin can and secure with 3x 6-32 shear pins.

Need to turn down upper counter torqued nut on piston because it otherwise doesn’t screw far enough in.?
We would rather have the piston cup assembly be too short than too long because we can only compress it so much when we do the last step.
Consider switching to words like "fore and aft"
Purchase 1/4-28" bolts that 3/4" long.
Cut the mission package to be 25" long.
