X adapter to Grenade
It's always a good idea to lay everything out and get a feel for how it all fits together before starting. I would build out the entire air system by itself first. The grenade fill adapter can be removed with a flathead screwdriver. The fill adapter hole is a 1/8-inch deep hole followed by a narrower threaded opening. As luck would have it the X adapter has the same threads but you have to increase the size of the initial opening in order for the X adapter to reach the threads. If you're careful this can be done without breaking the grenade..i.e. the fill adapter can still be used. Slowly increase the diameter of the hole with a small sander bit until the X adapter can easily grip the threads. Use red lock-tite to seal the adapter in place.
I drilled a hole in two PVC end caps and used epoxy to create a mounting point for the ASA. Once the ASA was secured inside the PVC end caps I uses red lock-tite to glue seal the 90 degree fitting, valve, and X fitting to the ASA. I would wait to cut the macro line until you know how thing will fit inside the launcher. I don't recommend applying air to the system until you're ready for final testing. The X adapters can be very fragile; this is why I recommend purchasing at lease one extra fitting (I destroyed 2 in the process). If the system isn't secured you can blow a fitting if you air it up outside of the launcher.
