Connecting shrader, blow off, pressure gauge
Building my first pneumatic and want to make sure i do the right things here. From searching ,i know i need to tap at double wall joints. Do i simply self thread them in after drilling and then coat on both sides with silicon or epoxy. I just want to make sure i don't blow one of these out.
Thanks
Thanks
It's pvc right??? Just buy the tap and the drill that goes along with the size tap, drill the hole straight up and down, not to the sides. If you have a drill press it's even better and easier. Next you might wanna put some grease to cut the threade easily and start tapping, once your done, clean off the grease and put on the fitting you want.

Im not saying this is a great idea but I use the non threaded kind, drill a hole, pull the valve through and wrap rubber bands around it to seal it off
That is all.
Thanks for the suggestions guys. Exactly what I needed. I want to tap as few holes as possible. I will go ahead and tap.
Yes - all PVC - schedule 40 with a 1" modified sprinkler valve
I am trying to find a piece like what these Systm guys used on their bigger pneumatic cannon that basically has the shrader, blow off, and guage all screwed into it.

Anyone know what that is?

Um I'd help but I don't really want to look over a 23 minute video, take a picture of what you are trying to achieve here and we'll help you out. If you want all those things in one, you could simply tap it a male tee, and add what you want from there, that will probably work, but again, im not sure what you're trying to do here.
If there are no threads on your valve, gram something with threads, like brass compressor fittings. Then drill a hole which allows a 'just fit' for the valve, then either solder or epoxy it into place.clemsonguy1125 wrote:Im not saying this is a great idea but I use the non threaded kind, drill a hole, pull the valve through and wrap rubber bands around it to seal it off

Or buy a threaded tee and buy the galvinised steel threaded bushings, that's what I did on my bb gun
That is all.

You can use a three-way manifold like thy use on compressors if you only want to drill one hole. At home depot or lowes they are in the air tool section for about ten dollars

Instead of waisting 10 dollars he could simply buy a threaded tee like I suggested, make sure its male threads and its the appropriate size for the tap, I'd try and get a 1/4" Tee with male threads. From there you could add another tee if you need more things added to this "manifold" type thing.

I just like how they say "300 yard tennis ball chuck" with a sprinkler valve... Seems like they might have measured wrong...

I'm not sure where the 300 yard reference is in this thread. I do know that an unmodified tennis ball is difficult to chuck 300 yards. I've launched them at 100 PSI and measured the range using a 2 inch valve with higher performance than a 2 inch sprinkler valve. The range is less then 300 yards. 200 is barely reachable in still air.
300 feet is easily reachable with a tennis ball.

Instead of wasting your time with tap and wasting the money, just get a threaded adapter and bushings, then it ensures no leaks or blow-outs.

Actually from what I've heard, you can actually tap plastics like PVC with only the metal fitting threads, you just wrench it on and it creates threads itself. Note, I haven't actually ever tried this as I believe you wont get straight threads but it might help save some money.

the best way in my opinion is to get say a 1/4" threaded hose barb and put the barb it your drill. drill a hole a little smaller than you need than drill th barb into the threads first and it wil carve its own threads. you can then remove it and put 1/4" fittings in.
