@Drummer0647 Cardboard substitute: I suppose you could use thin plastic for the upper lip. It's got to be thin, though -- in my experiments, even thin wood sharpened to an edge didn't produce as clean a tone as cardboard. As for the foot assembly, you can design anything that will create a windsheet. It would probably be difficult to roll plastic up into the traditional cone, but there's no reason why you can't make the foot the same cylinder with cut face as the upper lip assembly.
Constant pressure: My wind pressure actually isn't 100% constant. But it turns out that my blower is capable of delivering such a large flow relative to what my pipes demand, the pressure around my operating point is pretty much flat, and it doesn't make a difference. I recommend trying it first without regulation; that may be good enough. If you insist on regulation, you can read more at rwgiangiulio.
Covered ("stopped") pipe: It halves the frequency -- almost exactly, but not quite. You need to make a small correction -- learn more at rwgiangiulio's site. In real life, all stopped pipes have plungers to allow tuners to make fine adjustments. Also, stopping a pipe changes the Ising relations, so a mouth assembly that works for an open pipe may not work quite as well for a stopped pipe.
I want to build one of these for science olympiad but I have a few questions: Does covering the pipe cut the frequency in half? How do you supply constant air pressure to your organ? Would you reccommend pvc or abs pipe? (they are very similar but you can easily paint abs pipe as opposed to pvc.) When using pvc for the pipes, would you recommend everything that is not pvc to be cardboard or is there a stronger material that would work just as good but be more durable? Thanks!
Thanks -- I will let you know how I do. As well, inground sprinkler pipe is affordable, and built in vacuumc leaner pipe, is smaller and thinner walled than plumbing pipe. That's how I started this adventure. I didn't want to throw it away and challenged myself to find a use for it.
The languid is the sheet that divides the upper and lower halves of the flue pipe. (In this case, it's that little cardboard square.) It serves two roles, one with each half of the pipe: 1) as the nearly-complete wall of the foot assembly, it forms the flue, or the slit through which the windsheet flows; and 2) it serves as a wall of the resonating chamber.
For a clearer picture, you can Google Image search 'languid pipe'. Let me know if I can be of further help.

PVC vs ABS: Doesn't matter. You might consider whether one accepts glue better than the other.

What exactly is the "languid" (i probably spelled it wrong)

Considering your talents, I really appreciate your humble presentation. I am thinking that I might even be able to do this. Thank you so much.

A fantastic presentation. I hope there are lots of cardboard organ pipes out there as a result!
