Huh.
Mounted my sanding disc to my table saw yesterday to ease the edges of some 1/4" thick mounting brackets for a new top for my mobile workbench. Started up the saw, everything sounded/seemed fine.
Put my ear protection in. Started to grind a coupla pieces. Weird noise, but I thought that the sanding disc at work was the cause. Finished easing the edges and pulled my ear protection outta my ears. THUNK THUNK THUNK (at 3400 bpm)!
Frick. Something stuck in the saw? Open the cabinet. Nothing. Fire up the saw again. THUNK THUNK THUNK. Weird. Huh. Take the belt off. Spin the arbor. Smoooooth. Spin the motor. Smoooth....
Remove belt, try to move pulleys on arbors. Nope. Not by hand.
Put the belt back on. Slowly spin the motor. Thunk. Thunk. Thunk. Take belt off. Noise gone again. Put belt back on. Thunk. Spin motor backwards. *Very* light thunk. Check alignment of belt ribs with pulleys. Adjust so there is 'misalignment' of belt (shift ribs over 1 slot on one pulley). Thunk disappears briefly, comes back.
Observe both pulleys relative to thunk timing. Hmmm... perfectly synced with the motor. Damn. Frick. Thing is like maybe a year old. Well, got a five year warranty. Thank god for that.
So, I have very little desire to remove the motor from this puppy - three horse's gotta weigh like 150 pounds.... Gonna be a giant PITA for sure. Maybe it's fixable without removing the motor?
Anyone have a suggestion that isn't gonna make me cry?
TIA
