I recently picked up a used Powermatic 8 jointer and was hoping I could get some help on setting it up.
I got her home and ran a pass through the jointer, the results were quite bad. I inspected the blades to find they were quite damaged. Ordered up a set of Freud knives and the magnetic jointer jig from Rockler.
I tried to square the tables to each other, this model of jointer is only equipped with two adjusting screws per side. I got the plates adjusted, but the back right is under about .005”. With only two eccentrics and the weight of the tables, I just cant get to get them all within .001. Any ideas?
I set the blades using the jointer blade jig. Got the blades all reasonably close.
I ran the first test piece, much better than before. But I think there is still an issue. There are ridges running along the length of the board. I measured across the width, and it seams the board is tapering.
