			Hey guys
Going to get my new cannon built this weekend.  Found all my new pipe i will need.
Only questions i have are:
What is a reliable way to fill the chamber with air?  Bike valve, quick connect?
From what i have seen with the piston diagrams, i have noticed one thing.  If i use say a 1 inch barrel, won't i need a t that is larger than 1 inch?.  Is i use a 1 inch t won't that prevent me from sealing the piston to the barrel?  Maybe it's just me
Any help would be great

			for a 1" porting piston valve you will need a T bigger than 1" so there is enough air to push the piston back.

			to fill the chamber it depends on what you have. 
A bike pump: pump
Compressor: quick connect
Your lungs: quick connect  

			really good quote/phrase here
