Check out my APH guide: http://www.sscentral.org/homemade/aph/
I've tried to go out of my way to make this one as easy to understand as possible. While it's not 100% complete because the customizations page needs some more information, it's very close.
Could some people read through this guide and comment on it? I'm mostly interested in whether or not you think it is helpful to people new to homemade water guns. I tried to make everything as simple as possible and I spent a lot of time thinking about what sort of questions people will have. I'm sure there are some spelling, grammar, and writing flow errors in some of those pages at the very least.
Let me know what you think and if you have any suggestions. It'll help everyone out in the end.
