I agree, never ask an employee for something obscure (to them), and under no circumstances do you try to explain what a pneumatic potato gun is to an ACE employee, those were some of the most awkward minutes of my life...

I agree with you on that one. I tried asking for sheet rubber, all I can say is bad mistake. Go to a auto part store ask for a tire fill valve and the threaded ones will probably be next to them.

The guys at my ace get a kick out of my hobbie. They all recognize me and dont even ask if I need any "help finding anything" anymore. But if I do ask them, they know right where it is.

I have a Lowes and Home Depot where I live as well, and they are a bit cheaper, but I love Ace. They even have sch 40 pipe and fittings up to 4" here.

Also, if you havent checked, look into Napa auto parts, I found all kinds of schraders there that are not at checker or auto zone.

Unless you know the manager... One of the employees told me he used to build them!

Ghetto Wonders In The Realm Of The Spudgun Community

A rubber passenger tire valve, can be obtained from any local Tire & Service Center, in your area. - Although the PVC is approximately 1/4" thick, the tire valve can be pulled through, if you drill a 7/16" hole.

Ghetto, at best, but much better than trying to epoxy a stem out of an old inner tube!

Why ( I wonder ) do most people STILL talk about using schrader valves, when a better (and safer) way to fill your chamber is with a 1/4" Ball Valve, and a 1/4" Male Quick-Disconnect?

This way, you can always rapidly DE-pressurize your launcher, as well as mounting the fitting in the double-walled component-to-pipe area of your air reservoir.

You might try looking at Pep Boys if you are a resident of the U.S.A.

Schraders are much less bulky and therefor easier to incorperate into the design. Also, a lot of people do not have access to a compressor and use hand pumps. schrader are just more universal than quick connects. I prefer a schrader to quick connect unless the cannon is rather large.

I mostly agree with this sentiment. However, there are some designs where a schrader makes as much or more sense...smallish....
