Re: Plaction wheel shooter?

Thanks for the answer, Alex. Our shooter has a top speed of 6000 rpm. [Not sure we need to go quite that fast, but if the motors can, we'd better make sure it's safe.] If we change to plaction and use your riveting method, we'll make sure to carefully test up to full speed. I'd be worried about the centrifugal force focused on the relatively small area of rivets.

Has anyone tried some kind of glue for holding the tread on the wheel at high speeds? Then all the centrifugal force is spread along the entire circumference of the wheel. Repair and replacement might be difficult, and I'd still be a little concerned about the disc contacting the ends of the tread (that may focus a little more shear force there). If anyone has experience (good or bad) with that, I'd like to hear about it and learn from you.
