A look inside the "bleacher reacher" t-shirt launcher

I had a bunch of these to service and though I'd share a look inside:

Standard exhaust valve setup but with an interesting configuration that has the piston seal at the front endcap but avoids using a spool or "toolie" type valve. There's no rubber seal on the piston face, it's aluminum on delrin, and it has a floating o-ring to allow air to be filled from the main tank but not to flow back when the pilot is actuated.

Operating in the 300-500 psi range, these things are pretty darn loud!

Also did I mention my workshop has an epoxy floor :D

T-shirt cannon right? I think I have seem something similar somewhere.
Interesting piston setup, any chance of a video (launching something more interesting rather than T-shirts :D)?

I guess the post title of "t-shirt launcher" wasn't clear enough :P

nteresting piston setup, any chance of a video (launching something more interesting rather than T-shirts :D)?

Manufaturer's page, pretty pricey indeed!

Here's a quick video accelerating an empty soda can at 300 psi:
