The most difficult part of this project is to drill and thread the pvc cap for the 1/4 inch valves.
You will need the appropriate tap and die set (or talk really nicely to someone that does) to thread the holes on the cap.

Say, does anyone in Calgary have the appropriate tap and die set? *hint hint*

You don't need the die part just the tap part. It is a NPT1/4-18 tap and it's not going to be included in the typical tap/die set that you see at Can-Tire. They are fairly inexpensive and the drill size is 7/16". Mine has received a fatal impact with a concrete floor and will be replaced when my brain ram starts functioning again.
