Post your pumping pics

Finally trying out my new 2.5" diameter cylinder. It's taken some time and dedication to work my way up from 1.75", 2" and then finally packing the 2.25".

Still plenty of room before I can pack out the 2.5" but I'll keep at it. Once I can pack that out it'll be about as thick as a can of Coke

I pump for 5 minutes at about 15 then take a 30 second break. Here are the results after and hour session. That’s an 8” x 2.25 cylinder.
