You could have just posted this question in "Questions about the APH."
The materials list appears to have all the neccessary items, except the tools you'll need to build the thing--you can borrow them or buy them as a one-time investment. To my admittedly minimal knowledge, all you'll need are a hacksaw, scissors to cut the tape, a drill for the nozzles, and that's about it...though there are a few other power tools that might make cutting and everything easier. Your question is somewhat vague, so it would be more helpful if we knew what you thought was left out...
Where the backpack mod article talks about a drawstring, it refers to cutting that out if the trashbag has one. Many trashbags (especially the sturdier ones) do have drawstrings that are threaded through a loop around the lip of the bag, but they aren't needed and will just get in the way if they're used in a trashbag backpack. So no, thread isn't used in the design at all.

Please post your questions in the thread you started first. All posting elsewhere does is make me move your questions there.
Every PVC piece and pipe required is in the guide from my quick glance. If you believe any specific parts are missing, please ask.
On the backpack: There are two different definitions for thread. Pipe threads are the parts that allow you to screw-on something. The other definition is a thin string. I was referring to the first definition. Remove everything but the screw-on top part.

I don't think you have the T joints? (That's not what they're called, but It's PVC, there are 2 of them and it sort of looks like this: _|_ but, you know bigger and made of pvc)Ben wrote: Every PVC piece and pipe required is in the guide from my quick glance.

There's three Tees and they are listed appropriately (1 1/2" PVC Tee, 2 3/4" PVC tees). This isn't hard people - they're listed right there. I don't want to sound mean or anything, but I can't help you much when you have problems reading the article. I just want everyone to know that because I can't be there with you to help. Some people seem to expect that.

I only saw 1 1/2 inch tee, sorry Well, I guess it does have everything then...
And where do you get your check valves? (I'm in ontario canada if that helps) I've got everything but those darn check valves!

I suspect you moved the 3/4-1/2" bushing to before the second check valve, correct? Unfortunately, you would need two more and correct fittings or a reducer for the second valve. I'm just posting to make sure you didn't intend to use a 3/4" pump tube--that would be hard to create pressure with, and you'll see a note in the Pepper's Homemade article pointing to the wide pump as the source of poor pressure.
Actually, they might even have reducing tees--the sides are 3/4", and the middle is 1/2". Now that would be perfect!

Well, all I can say is to keep on looking (if you want decent performance, that is)! Who knows, even once you do find good couplers/reducers/bushings/etc., you can keep this as a fast-pressurizing shotgun sidearm.
Just a note, though--the fittings Ben used and the ones I came across are bushings. Basically, one end is a spigot and has the same OD as 3/4" pipe; thus, it fits right into the tee for the first PC. The other end is just a socket, so you use glue and fit 1/2" PVC into it. Ask at plumbing stores (I understand you probably don't have a Lowes or The Home Depot), and you just might come across the right part.
