Hybrid Kicker

The latch is then released.

However I believe there are some very serious saftey issues coming into play here. Precharging a cylinder and using elastic bands to increase the kicker velocity puts the cylinder well outside its normal operating velocity. From other posts it appears that the cylinders will degrade and become dangers if piston is moving at speeds around 20 in/sec.

From the video I can't determine the velocity of the piston, but it appears to be moving extremely fast. Because a damaged cylinder could kill someone I highly recommend that you determine the piston velocity and if it is even 15in/sec reevaluate your kicker.

Thanks for the explanation.

I'll have to look into the final velocity that our piston will travel at. I also saw some of the posts speaking of the dangers of having pistons move around 20in/sec...
