Thanx for the compliment- I got new wheels!!!(used the old ones for testing) but going into production is a s-t-r-e-t-c-h!!!!! I made this 15 sec. vid to show why I made what I made- the first attempt on this type tensioner (single wheel) went on the Spiderbox- it works but wears the wheels pretty fast (too much spring tension) and I can still hear chain slop from time to time.
