Before you rework the whole thing!!!! I like the mount!!! Try walking arround a good hardware store or two...

Look at Rat trap springs and other springs of similar nature! I've been doing some thinking myself. I want to see this thing work for you safely! You seem like the kind of guy who will give feed back... And are also 1 step ahead of me. I thought of one of those springs that hold screen doors shut. The kind that are not long(snake like) but C shaped that rock stationary and snap (hold tension) on the door when closed.

Are you familiar with what I'm describing or should I send a pic? The spring is small like the chain tensioner but snappier. It has two rubber rollers (one on each end).

Please be carefull. Chain derailment is no joke!
