that is how you mod a valve

also i wouldnt use those old fittings, they've been sitting in the sun too long and will probably blow up

ok i understand a "little" better now. although i still dont get it perfectly which I dont mind. All that i care is that my gun shoots. So if I put a schrader valve somewhere on the air tank and fill it lets say with 60 psi. Then when i pull the blow gun will it shoot without being hooked up to the compressor?

yes it will, really, replace those old fittings, yellow pvc aint right

i think he sould jsut go buy all new parts except the valve, all that stuff looks pretty unsafe

yeah, saving a few bucks isnt worth goin to the emergency room (which will cost alot more than new parts) and also, PVC doesnt show up in X-rays so the DR.'s will be doing hit and miss to try to find all the shards

and most likely they wouldnt find all the shards, that would suck beond reason

all the parts are brand new. i just bough them today i just had some old parts on their to see what parts and size i needed so i wouldn't be spending a long time at lowes to find the parts.

Ok I think I finally understand. I have heard this before and never got it. I have also taken the valve apart but from looking at it quickly I still didn't understand. Now that I had the time I took it apart again. So tell me if this is right. Their will be equal pressure above the little black rubber. Then when I open a hole using the solenoid or a blow gun it will let a little air out. Therfore since they are not equal all the air in my tank will come out. Correct? Well I am glad I "think" I get it. Here is a picture of a tire pump will it work like a blow gun? If it will work I don't care if the gauge doesn't work. Also here is my gun with the correct and brand new pipe. I already glued on the cap but realized to put the schrader valve on I needed to cut it off. So that will be attached on the end once I go get another cap. So does it look like the gun will work? If I find out that tire pump will work I will modd my valve today or tomarrow.

Thnx

how is that thing a tpe pump, that looks more like a blowgun to me, i think its just a tire pump bit for a compresser after a blowgun, so that should work. and r u just going to put a coupling over the pipe to reatacher ur schrader valve?

"and r u just going to put a coupling over the pipe to reatacher ur schrader valve?" I was planning on it but I kinda was thinking wouldn't that be a little dangerous? or would it be fine? I also was thinking of changin it alttle putting a tee near the top of the tank near were i would be holding it the putting a capp on the end then a schrader valve. and then just a cap on the end. but i dont know. one more thing tell me more about this pill bottle gun. I seen a couple on here but I have never made a combustion gun. Can i use a regular lighter? or do I need a bbq ignitor?

Thnx

u dont use a bbq lighter on pill cannons u just rip apart a long nose lighter and take the sparker out of it. read all the pill bottle posts it tells u everythingu need to know. also if ur goig to change some things on the barrel put the schrder valve on the side of a fitting where theres 2 layers of pvc so its stronger

that blowgun should be fine, the gauge will serve no purpose there, so unscrew it and (it should be 1/8" NPT) drill and tap another 1/8" npt hole in your chamber (double layers!) and screw the gauge in there, that way you will know how much pressure is in your chamber and you dont fill it past 100psi by accident. for your mod you will need to take off the air compressor quick connect (black thing on the bottom of the blowgun) and put in your 1/4" hose barb, or a 1/4" nipple if you want to attatch it straight to the valve

Ok I understand how this works it is very simple. I am talking about the pill gun. I took apart a lighter those long ones and took out the sparker thingy. Now if I touch one of the wires and push the buttom I get a spark. Although when I touch the other wire nuthing. Its a brand new lightetr I just bought. It work fine and light a flame before. Whats wrong are both wires supposed to spark? I started to make a cannon and in between my to screws there is no spark. I m guessing their needs to be. My screws are the right kind idk y the lighter thingy wouldn't b working right. Could someone plz help me with a solution?

Thnx

if there isnt some kind of coating on the screws it should be fine, as for the ignitor, tape a piece of wire (just any wire you have laying around) to the bottom, then put the other end of the wire on a screw, and attatch the wire that is on the ignitor already to another screw

Ok I got everything needed. I went to The Home Depot today and got just about everything. A got a couple a 1" x 1" male threaded adapters. These are needed for the different size barrels I will have. I got some other bushings and adapters to attach my barrels to those threaded adapters. I also got a coupler to reattach my cap. I decided to just go with the way I had thought of before not using a T. Next I got a couple of end caps to make some PVC rockets. Now I have everything glue together. It all looks pretty good. I still need to paint it. Now the only thing I didn't get was a blow gun. So that will be needed before I can mod my valve and get the gun working.

Now about the pill gun. It is very cool. I have had lots and lots and lots................ of fun with it. I have a clear bottle so it is very cool. The only problem with it is after I shoot depending on the size of shoe cleaner I put in it gets pretty hot! I am contemplating if I should cover it in alot of electrical tape or something so it hopefully doesn't get hot. Although by doing this I won't be able to see inside:(. But overall this little gun is AWESOME! The pill jar I used is alot bigger then most ones I have seen. It is about 3" in diameter and about 6" long.
