i want to build one of these to shoot it in my house is that possible, can any part of the net harm anything in my room like my lcd and can i customize the
lengths of the rope so its not to big flying across the room (I want it to be able to catch my friend) thanks

I would have to warn against doing this without changing some significant things. The net itself is 9.5 feet per side, the tractors and strings add another
foot, at least, in each direction. If you hold the net gun at chest level the top of the net can be somewhere around 15' above the ground and almost 12'
across, you would need a really big room for this to work. As soon as any tractor hits anything, the whole net will stall. The only time I fired this inside, I
was in an enormous garage and it was my first net gun that used a smaller net.
I think you will have to use a much smaller net (and figure all the corresponding net math), thicker foam on the tractors, possibly lighter or smaller
tractors, and maybe reduce the pressure. I am pretty sure the net gun could harm lots of things in your room, including the LCD.
It is probably easier to just ambush your friends outside.

The link that you give for the net, is that a pre-made net because it looks like it.

The net itself is pre-made, but you can't just pull it out of the box and put it in the net gun. You get a long length of net, but you still have to cut it to the
correct length, add the spreader string, and attach the tractors.

I did everything you said to do with the Trigger Valve System but when I put air inside the chamber is leaks out of from that hooks to the tennis ball
attachment and also when I press the blow gun it does nothing. What am I doing wrong?

Never mind about my question. I put the wrong end towards the pressure chamber (the arrows were pointing toword the pressure chamber).

First make sure the flow arrow on the valve is pointing in the direction of the air flow, back of the arrow towards tank, pointy end towards outlet. Next, put
some air in the pressure chamber and see exactly where it is leaking from. If it is leaking out of the small "nipple" in the center of the outlet (step 4, fig 7)
than you need to seal that off with some more epoxy. If it is leaking out of the outlet (and not the nipple) than it is likely the diaphragm is not seating. This
can happen if PVC chips get stuck in there, just disassemble the valve and make sure the seating surface is clean.
I went through some similar issues earlier this link *might* (direct link to comments seems flakey) take you there. If not, go back to the May 31, 2009
comment string in Step 5.
If none of this helps, post the things you tried and I will see what I can do. Good luck.

Love the trigger mechanism (with a safety system and everything)
I think this takes the cake for coolest functional PVC based ible I've ever seen, full-stop!

You da man. I have wanted to do just this for years. Next work on the Bathook... the grapling hook launcher.
