Hi guys,
I have a Grizzly jointer that's a couple years old. Since I bought it, I've wanted to redesign/rebuild the motor mount. The way it came, it's pretty hard to get the belt tension, motor position, motor level, and so forth adjusted all at the same time.
I've been looking at my Jet 15" planer to see how they made these adjustments so easy. On that tool, the motor is mounted on a swinging plate. Since the hinge is mechanically at the correct angle to keep the motor straight, the belt tension a separate adjustment and is mostly provided by the weight of the motor. An additional threaded rod and double nut lets you fine tune the tension and keep it steady. This seems like a better design.
Has anyone done anything like this on the 490x? I really dread belt issues on the machine.
Thanks,
Larry
