I am working on my planer, which came partly in pieces. Today I was making the bed parallel to the head, setting roller heights, etc.

I'm using a Powermatic gauge, a long lever and spring deal that has about +/-1/32 travel. It's about 8" long. I made the bed parallel to the blade, set the infeed roller parallel and height. I went to work on the chip breaker and decided it would be easier from the other side. When I changed sides, I don't remember if I adjusted height or not.

When I got to the other side, the planer blade was no longer parallel, off a little less than 1/64". This was pretty alarming, so I went back to where I started--this was also off. I started over and it looks like when I adjust the bed height the parallelism changes.

The only thing I've been able to come up with is that if the bevel gears in the up/down mechanism aren't snug, maybe this would happen.

Any help will be greatly appreciated.

Thanks,
Steve
