I want to build a pneumatic and was was wondering if this design is worth putting together. It would be a 2"x36" chamber and barrel with a 2" barrel sealing piston using this
http://www.spudfiles.com/forums/viewtopic.php?t=6214& . Also I was wondering is mouse pads would work for seals. Finally are there any GGDT tutorials on how to use it because it said this design could shoot 200 yards. I have a bike pump currently and maybe an air compressor but I want it to be portable.

should work just don't mess up the valve it looks complicated and if u want it to be portable put a schrader valve on the chamber and got to your local bike shop and pick up a co2 tire inflater they use 12gram cartridges and would be perfect good luck

Do you know how many of those it takes to fill that chamber to 100psi? Alot. Go check out the 12gram CO2 chart stickied under pneumatic cannon discussion I think.

Mousepads work really well, as do neoprene pot holders. My friend's mom brought some home one day she's like "Can you use these for the cannon?"
I don't know where exactly she got them, but they basically look like mousepads and have a furry red or blue covering on one side that if you peel it off reveals a REALLY squishy sealing surface.
