 I saw a big opening in the bees section and asked if we could sit for this match and was told we were welcome to sit there. Your team made space for about 15 of my team members that came with me. - Debbie [more] |

Dang, that is extremely cool. This is the first I've ever seen or heard of this use of a kit wheel.

Andy--there might be a market for a small aluminum sprocket with a bearing pressed tightly into it.
McMaster sells steel idlers like that....they're kind of heavy and big.

If AM' sold something like this, I think alot of teams would be interested (including us, as we no longer have any extra KOP wheels)

(Ingenuity aside...) Why use a bearing when nylon has been proven by many teams to be just as effective? Even a brass bushing would be less expensive and probably lighter than a bearing. The efficiency loss between the two is somewhat nominal; this year's FTC shooters are a good example.
My current favorite chain tensioner sprocket:

At the very least I would take 3 of those bolts out to save some weight, all 6 probably isn't necessary for an idler.
