    It's probably backordered so they can install the bearing. Sorry, I couldn't resist that one.

    No worries. Give it a couple of years and most people will stop mentioning it

    UPDATE

    Gas strut came in. I figure with the 8" wheel the bottom belt will be at an angle from the contact wheel to the drive wheel. If I would change to a 10" or 12 " contact wheel it will straighten the angle. Attached the tracking wheel as well as added the gas strut.

    I think if you change the angle, you will change the amount of force on the idler arm. I think you should mount it as close to a right angle to the idler arm as possible - like the hammer in the mock up. Any mechanical engineers that can confirm this?????

    Actually the bottom of the belt angle does change with the size of the contact wheel as I found out in this picture of a KMG grinder with a smaller contact wheel
