If anyone would like more info on it let me know and maybe we can post a vid or something along those lines.


EDIT: DISCLAIMER - This was legal in 2008, we haven't looked into it's legality in 2014.
I see a potential problem with this device depending on how the system is pneumatically controlled. The cylinder may be considered a second compressor if it restores the air used to push the plunger back into the storage devices when the plunger is re-cocked. In this case, I'm assuming something mechanical is re-cocking the cylinder. A solenoid valve would have exhausted the air to atmosphere in both the forward stroke and reverse stroke.
