Re: pic: Practice DT
Have you put any thought into sizing the drive belts and pulleys for this application?
It seems like you're using 9mm HTD belts with pulleys that can't be more than 24T. We have definitely had ratcheting and strength problems using 9mm wide belt with pulleys about that small. I would check the Gates spec sheet or run a test chassis before you bet your season on what fits most conveniently. I really think for a west coast setup you're going to want 15mm wide belt.
Also, relying on a 17mm wide pulley to fit two belts that are "about 8.5mm wide" seems like it's asking for trouble. Absolutely zero extra space for belts on a pulley isn't a great idea.
