Rubber Band Chain Bar

Hello. This is Team Caption from 77000X. Anyone know how to rubber band a chain bar.


I should be banned from drawing in engineering notebooks.IMG_20181209_172700.jpg
Hopefully this explains everything.
EDIT: sorry, but your neck will have to go through a bit of strain…

If you look at videos of StarStruck robots that could help. I know that most didn’t use chain bars, but it could give you an idea of how to place the rubber bands.
