I’m surprised to note the brushes have worn out after a year?? are you defo sure worn brushes are the problem? if they are worn, either they were defective in the fisrt place or there is another problem causing them to wear out so quickly. I have no experience of the Delta model but I have a Jet 16-32. On mine there are in effect two controls. One to start the motor for the cylinder and the other has a speed controller for the conveyor belt. Even when I turn the conveyor control on there is a hum from the motor but the belt doesn’t start to turn untill I crank up the speed to about 10 on the dial. If you are hearing a hum that is a positive sign, at least power is getting to the motor. If it were brushes it may be noiser and spark a lot. That sais I had an old Delta chop saw and the brushes welded themselves to the motor and guess what, they stopped making the brushes so it ended up in the trash. I would think before I start shelling out for brushes (which may or may not be the issue) I would check all the simple issues first. Is there anything jamming the drive belt? such as sawdust, sliver of wood, a dropped or misplaced too etc? Could it be that the conveyor belt has tightened, meaning the rollers wouldn’t be able to drive the belt causing the humming noise. Have you checked all contacts on the starters and motor, they too could be clogged with sawdust. A gentle blast with compressed air is worth a shot. Good luck with it, I know how frustrating these things can be. David -- No one plans to fail, they just, just fail to plan |
