Re: Are any teams planning on shooting the ball?

What I meant to say was that the result of using the 3/4" cylinders is a faster velocity on the ball after firing. We did some testing using a complete vertical shot on the ball and two 3/4" cylinders made the ball travel higher than two 1&1/2" of the same stroke. Any ideas on increasing the output of the shot. We already made a huge difference by placing storage after the regulator, but before the solenoid. Any advice would be appreciated. We have recognized some friction issues with our linear guide and we are considering switching to one of the micro series linear guides from NSK, because of the benefits of the bearings over the low friction plastic sliders with what we use now. Also we are stiffening the track that the guides ride on, because at current they are only fixed at one position. Adding a second attachment point should reduce some of the binding we see with the single attachment point. Right now we are unreliably shooting over the rack if we aren't lined up perfectly on the rails that are spaced wider. At the 14" points the ball bounces cleanly over.

Thanks, Charlie
