| I am putting my new Powermatic together with some difficulties. The table is flat but when the extensions are bolted on there is a total bow up across the full width of the table. I removed the extensions and thoroughly cleaned the surface that bolts together with no improvement. Next I switched the extensions to the opposite sides with no improvements. Using the feeler gauge the gap is about .020. This appears to be pretty excessive considering the tolerance on the inspection form that came with the saw says .010. Any insight? <!—-><!—-> <!—-> |

Shim it with either brass shim stock or masking tape. Just shim on the top half of the mating surfaces. You could probably even just loosen the bolts and slip some paper in there and trial and error it until you've got it close. I wouldn't sweat it too close anything less than .010 you would probably never notice in use.
Someone here will probably be able to give the thickess needed to negate a .020" bow but I'm guessing one piece of tape per wing would do it.
Surprising with a Powermatic, I thought their QC was better but the design is time-tested so after you fix this you should be fine for fifty years or so.
Good Luck.
Thanks for the ideas. I am off and running.
I used tin foil on my PM66.
