    Nice way to maintain the chain tension under constantly changing conditions. I like the way the sunlight sort of filters in the area of the tip while you are running, make it look like the whole thing is lighting up under load!

    I like it!!


    Bob, I know you already know :)

    How many pounds of spring pressure on the idler?

    Does it help with the wave?

    Ah ha - I see you have spotted my (evil?) plan.

    Actually I don't know - yet! I was hoping to set the chain tension using a torque wrench on the idler tensioning bolts but even using my in/lb torque wrench doesn't register. The vid was run with me just applying some hand pressure to compress the springs and then tightening the locking nuts.

    I will take it to work and measure the spring constant - then by just measuring the length of the spring it will tell me the spring pressure.

    Does it help with the wave? - out of the wood it sure does. In the wood? I dunno - I can't stick it into any logs. I'm 8 miles from the milling yard and just over a week ago some idiot texting on his cell phone while driving ran head on into my van!!!

    I want to turn up some proper spring retainers rather than using washers. Lucky there's a heap of oil being flung around at that end to keep everything lubricated - there will be even more when I add the aux oiler.

    Great stuff Bob,that tensioner is also acting as a torque strut.You may enjoy decelerated wear on your bar in general with that.


    I sure hope that you're visiting the patent office with some of these innovations Bob.Lest some mankey mick make a million bucks off your intellectual property......:yourock:

    Good stuff there Bob. I noticed that the chain on my 50" bar comes way off the bar when I blip the throttle out of the wood.
