Jim,
Really like what you have done. Great effort.
What thickness insertion rubber are you using?
I have access to a used conveyor belt that is at least 10mm thick x 600mm wide - could be a bit of overkill and unnecessary weight!
Cheers,
Rohan
Hi Rohan
Use the conveyor belt mate, I think what I used was 8 or 9.5mm can't remember but boy is it dear. $42 pm for he 300mm wide.
