  2. I took the plunge today to fix the pulley location. Instead of removing the top, I tried Smallpatche's and Fred's sugestions. I used a hex bit socket and when I rotated the pulley in the exact right spot, I could rotate the sets screws. Both of them were completely loose and the shaft key was sticking out about a 1/8". I added locktite to the set screw threads when I reinstalled them but the pocket for the set screw was so deep I am not sure how much actually ended up on the threads. I still don't like the blade height shaft damage but from a functional standpoint I am sure it will work as is. In any case, I am back up and running with about 3/8" clearance between the pulley end and the blade height shaft. Thanks for everyone's help.
  3. Thanks for the advice. That makes sense. I suppose the only way to check the set screws is to remove the table? Not looking forward to that.
  4. Good morning fellow woodworkers, I have a delta tablesaw problem I need to fix and have received no feedback from Delta on the e-mail I sent them regarding my problem so I thought maybe you could help. I purchased a Delta model unisaw with a 10" dia. blade, 3 1/4 HP motor, 52" table, and a Biesemeyer fence system in 2005, model 36-812 with serial number 05A 95089 type 2. An unusual noise is produced sometimes as the blade is spinning down from use. This noise was produced since I purchased the saw, but I could never find the source of the noise, until recently. When cleaning the saw, I noticed score marks and flats that had formed on the shaft used to adjust the blade height of the saw. Upon further investigation, there is direct contact between the end of the belt pulleys used to drive the motor and the blade shaft. Apparently time was required for the flat spots to form on the shaft. Until this occurred, the root cause of the noise could not be identified. This contact only occurs when the blade height is set to 2 inches or above, which explains why the noise was inconsistent and was not made all the time. When the blade is set at a height lower than 2 inches, no noise is produced. I have attached a PDF file which has pictures to showing the exact condition I am referring to. Obviously this is not a safe condition and shouldn't be occurring. Has anyone else had this problem with their delta tablesaw? Anyone know what is causing this contact to occur and if it can be corrected? If so, how? Any advice would be appreciated. saw_hoffman_03-09-2020.pdf
