Any chance you can shed some light on the size and type of cylinders and solenoids being used in this design?
Thanks.

For the shooter the solenoids are very similar to these:

Each solenoid valve has a 60psi tank attached right to the input it to keep maximum air flow. On the output sides each solenoid is plumbed with two tubes (a brass tee to two 1/4" tubes) to the cylinders on both the retract and extend.

The 2 shooter cylinders are 12" stroke, 3/4" bore, and cushioned on both ends.* Both the cylinders pre-pressurized and are held back with a 3/4" bore, 1" stroke pneumatic trigger cylinder.

All other solenoid valves are the smaller Festo valves.

*We had a similar design in 2014 and had a problem cracking the tees on the cylinder ends because of the shock loads of the shooter at the ends of its stroke, hence the cushions.

Hope this helps!
