Pneumatic speed

It was an idea I got from 1986 last year and our team probably won't be doing this, but I would love to see a prototype of this

I don't believe that Titanium did that for speed, I believe it was done so they could have more than 2 positions for their shots to be angled at...The problem with connecting them in the way you envision is that I don't see a method to secure the cylinders in the middle in any particular way. You would have to find a method to securely mount the rod to one end, and the other rod for the "punch" as well as have the bulk of the system moving.

Yo dude, they have threads on both ends.

I believe CalTran meant that if they were suspended say in the air, the extending shafts could easily bend or break under their own weight or momentum. Thanks for standing up for my idea though. Appreciate it

To "help" the cylinder's piston extend much faster, perhaps something like a spring or latex tubing can be used to 'pull' it out...

Gee, you don't even need to supply air to it, just release it somehow to extend (under spring power) and let the air out of the other end. Then pressurize the other end to retract it and stretch the spring agai for the next shot.

You mean like a spring piston? I believe Bimba sells them.

Sounds like 3138's 2010 kicker, which could kick a soccer ball cross-field with ease.

Who said the pistons had to punch the ball or even apply force directly. Also I know Titanium did not use this for speed. I'm just saying this was the other useful option I can see in the design.
