Unread postAuthor: NinjaFish » Tue Aug 04, 2009 6:42 am

Hey guys,

Its been a very long time since i made my first mini and stalked the forums to make more advanced Cannons. However i didnt get round to it and ive basically forgotten all of my knowledge on Spud Guns. :(

So ... can anybody please tell me how to connect my schrader valve to a copper endcap and not melt the rubber inside and ruin the valve.

Any help is gratefull thanks :help:

1. Remove the rubber.
2. Epoxy it in.

Try not to solder that fitting, just use a high strength epoxy.

Thanks alot! :D I figured out how to unscrew and remove all the inards with this tool I have. Now its just a case of removing the rubber. Id say I have removed 98% of it so far with a stanely knife. it's just the stuf in the grooves, will sanding it or using steel wool do the job ?

Try useing razor blades I find they are the best for removing rubber from shrader valves. Also yes sanding will probably work but afterwards remember to rough up the metal that needs to be epoxied because the epoxy needs a rough surface to adhere to. I do not think that steel wool will work it will probably clean the brass though.

You can tell how awesome a cannon is by the pressure used.

You can braze it in... just remove all the internals in the valve.. braze it in and then put the internals back on you'll get a better seal than epoxy... But epoxy is also a good way to do it :) your choise... and I dont get how you forgot everything about spudding..

A thing learned well is always remembered...

DO NOT braze drawn copper.

The temperature required for brazing will anneal the copper, lowering its safe working pressure.

Sweat (solder) with 95/5 Tin/Antimony and flux, or epoxy such as JB weld.

Fill valve in a pipe cap

Unread postAuthor: Technician1002 » Tue Aug 04, 2009 11:51 am

The rubber can be turned down a little in a drillpress and installed into a pipe cap. The rubber would then form a gasket as it screws down onto a pipe nipple.

Example photo attached.
