Something has changed inside me.

It's ridiculously overcomplicated, and I love it!

Haha I like the idea of it but don't have the patience to deal with designing it. The design could be made simpler by using PC fans and propane metering.

The compressed air tank is for the air cylinders. The shooting range was too far away from power.

In regards to the green compressor, nice dual two stage compressor setup. That should be able to provide 185PSI air all day.

Yeah, but its being used on lego air rams ! :roll:
That homebuilt one on the breach does seem to be leaking but still...


I've just realised that the first pneumatic canon I ever made (years before I started spudguns) used one of those lego pneumatic systems, I had geared the motor and connected it to the pump. Onboard compressor ;)

A fully automated combustion gun and it's a 'spray-n-pray'? For $20 less in parts it could'a been metered.
