New Jointer Vibration, G 0490 Griz
I rcvd my new jointer last week and now have it fully assmbled. Unfortunately, it has a massive vibration. I have spoke with Grizzly Tech service and they are researching this. Hopefully they'll have answer in a few days. In the meantime, I figured I'd tap into the collective experience of this forum for some help; hopefully.
Jointer runs w/o any vibration after start up. The vibration occurs in a small part at start up but really makes a racket just before the jointer comes to a stop. It appears(just a guess) that the vibration is a function of the drive belt. The motor pulley and the cutter head pully appear to be lined up well. In addition, the set up instructions ask for a 1/4 inch deflection on the belt after all is tightened up. Because of the way the motor is mounted on the machine, I can't get the belt tension deflection under 3/4 inch. I have tried having a friend help, using a 2 x 4 for leverage and other things to get the belt tighter, but haven't had any luck getting it tighter. I'm not sure this is the problem, but I'd sure start with this.
If anyone has an idea how to get this tighter or another problem that would contribute to this condition, I'd appreciate the input. I really don't feel the jointer should be run with this type of vibration; it'll just manifest itself in things falling apart, or damaging themselves eventually.
