Is this too hard of a build for me?

I'm thinking of making this.

Image
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.

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.

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

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.
