Tried. At lowes they have small pipes as small as 1/4 maybe smaller I just need to know a good ID for the barrel and chamber. Also wat kind of metal I should look for.

I am but I dont want it shipped I want to pick it up. Does anyone have a gun like this with different tubes if so tell me the tube dimensions. I just needa finish wat I started.

Lol your video inspired me to make it. I cant find the 8mm ID brass pipe
or 1/8in ID brass pipe. If there is any other pip that I can use instead please tell me. I checked at lowes and home depot. I even checked online and can't find those pipes.

That's mest up can u type a tut up for ur pen gun?

can someone point me to a tut>?

Checked locals

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

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

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

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.

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

I'm thinking of making this. http://www.spudfiles.com/forums/files/howpneumaticpengunworks_868.gif 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 bras...
