Topic tags/keywords: question

Soo At this point I have had the tables pretty near perfect
Twice. When I raise or lower the infeed table to adjust depth of cut I’m getting out of
Parallel. My question is, when adjusting the tables, do you completely loosen the locking lever and completely loosen all
Of the set screws? If yes, the table falls
To its
Lowest point and I would need 1/8” feeler
Gauges . Any thoughts ?

So yes to loosening the locking screw.
The dovetail gib screws you leave alone, you loosen and tighten them based on what you need to do.
You don’t loosen them all.

You probably will need some brass shim stock to place toward the bottom of the dovetail ways. That will lift the far end up, usually what is needed as the weight of the beds cause the most wear on the ways toward the bottom.
Use light machine oil on the ways. Or WAX. I prefer the light machine oil to keep them lubricated.

Thanks Jeff , but I don’t think it has jib screws. It has a parallelogram design. No dovetails

There’s bound to be some other pimp surfers with a paralellogram jointer out there.

If not maybe try powermatic(jet) technical support. They’ve helped me a few times with my machines.

Thanks Red. I called tech service and he kept asking if it was coplaner . I called a couple times hoping to get a different tech guy. But apparently there is only one.

The manual covers adjusting the tables pretty well. If you are adjusting the eccentric bushings for coplanar there are actually 2 lockscrews per hole. one has to be removed to loosen the other. If the tables are in the same plane (coplanar) at the top they should remain that way throughout height adjustments. I had the same jointer and once set up never had to readjust it.
