Default Chain clearance

HI gang just thought this could be helpful in trying to get chain clearance.
I took a scissor jack out of the trunk of my car, placed it where I need space and cranked away.
Worked like a charm. I put a nut and bolt where the wheel mounts to the frame, to hold position and bowed the frame and got perfect clearance.
Happy Motoring Robonyx

I put some bow in the stays by jamming a wood block between then tightening down nuts on allthread where the hub goes. Now chain don't hit stays.
