Have a Powermatic 66, and the blade won't raise all the way up. The saw is at least 20 years old and this has never happened before. Had the blade lowered for some cuts, and when I went to raise it, it wouldn't go quite all the way back up. It stops maybe 1/4" from all the way. I'm thinking maybe it's just the gears are gunked up? I tried getting up in there and scraping the teeth and spraying some PB Blaster up there, but it's difficult to get in there. Is there any good way to get to the gears besides removing the top? Any other ideas on what it might be?
Thanks in advance!
