I have one too!
I am doing the bearing thing too. I pulled it apart and they look like pretty standard bearings. I will check with the local machine shop.
I used a friends Delta saw the other day and discovered a few things that I want to fix. His saw was much quieter than mine. Mine has bad bearings.
Also in changing his blade there is room for a 2nd wrench on the back side of the arbor. I have always had to use a block of wood to wedge against the blade.
In taking my saw apart I see the flats on the arbor for the 2nd wrench. It is just that they are pushed in so far that there is no clearance for the 2nd wrench.
Mike (or anybody with this saw) I was wondering if you change your blades with 2 wrenches? I have a picture of mine I can send or post as appropriate.
I was planning of using a washer to move the arbor to the side more to give clearance, but this will change where the blade pops through the throat plate.
Anyone have any thoughts or experience with this?
Thanks in advance, Bob
