Nicely made, you failed to mention what pressures you're getting though ;)

Nice indeed. Does it work properly, does everything seal?
Beware of the checkvalve, if it leaks your pump will become a ram.

Now go exercise! :D

but you have a big dead volume between the O ring and the check valve so you will get to the point you compress the air in the cylinder and cant pass he cant pass the check valve
