explode your starter pulley

How'd this happen? Too many wraps? Slack rope caught in the flywheel?

2 wraps get wedged side by side in the pulley causing the pulley core to separate from the force. With properly sized rope, there isn't nearly enough room for 2 wraps to be side by side so the wraps stay stacked on one another as intended.

What is a better word or description for 'the pulley core'?

Makes sense, thanks.

I have used small string to separate things by wrapping it tightly over itself such that the compression force of each wrap adds to the ones below, and as they try to slip past each other, they wedge things apart.

Leverage with string.
