Help with mini valve gun

[Proxywars]

I'm thinking of making this.


I will need:

• 1/8 in id brass pipe
  hot glue
  soft rubber
  1 small screw
  1 small nail
  epoxy
  8mm ID pipe
  Shrader valve
  Pen cap

I believe I will follow these steps

• Make a piston from hot glue inside the brass pipe.
  Assemble a piece of rubber onto the piston and apply the screw.
  Glue a nail inside the pen cap.
  Glue the shrader valve into the brass pipe.
  Grease the piston and slide it down the brass tube.
  Glue the pipe into the brass tube 1/2 an inch away from the piston.

Correct me if wrong as this is my first pneumatic pen gun and my introduction to spudfiles.[/list][/list]

it's all in this thread: http://www.spudfiles.com/forums/pneumat ... t7858.html

I found that an all rubber piston cut from a sheet using a sharpened tube is simpler and more reliable.

Idk where to get a thick sheet of rubber or what the silver thing on your gun parts are =p.

[jackssmirkingrevenge]

How about this one, no silver things, just rolled up tape. and epoxy

Mouse pad rubber wine cork... use some imagination...

[Proxywars]

Lol i'll buy a mouse pad than haha. I'm going to use the concept of the tape and epoxy =p. So did you epoxy the tape for extra strength or just put epoxy onto to stick to the internals.

[jackssmirkingrevenge]

I wrapped the tape around the barrel till I got the internal diameter of the chamber, then epoxied it in place.

Okay cool thanx for the help I'll get started on looking for the parts now.

Where can I buy these things?

• 1/8 in id brass pipe
  8mm ID pipe

I have the rest but i just need those pipes

[sharpshooter11000]

I bought some off eBay in 12" lengths for relatively cheap for other projects. Google it and there's loads of results. 9mm K&S tubing has an 8mm ID.

I can't find this stuff at all can someone get me a link to it or a specific tutorial with findable tubes?
