Washers on Sprockets

[ezygmont708]

FIRST Team 708 has traditionally made spacers from 1/2" and 1" delrin rod. They have proved extremely durable and are very easy to machine.

We're thinking of using metal spacers instead. What difference would it make?

I'd use 2 extra nuts before I use a stack of washers like that...

If the washers tighten up and stay flat then you should be fine. We've stacked a washer or two as a spacer before and never had any problem.

Making a small metal, plastic or even wood spacer is the "right" way to do it, but they all function the same way.

The only reason why I'm concerned is that last year our bolts sheared out of our wheels and snapped.

hey guys
we typically use various sizes of these types. they are so cheap, its almost not worth making your own.

you can buy nylon spacers at places like Lowes, Home Depot, Ace hardware, etc.
