Well hello guys, this is my first post, but I’ve been here lurking for awhile. I was looking for a little help with tool setup. Recently my father, a devoted woodworker, purchased the Powermatic 8” jointer with the helical cutting head. This was very good for me since I became the recipient of his old Rockwell/Delta 8” jointer that has served him well since 1983. I should be getting that in my shop if the rain stays away in Houston tomorrow. Anywho, in setting up his new jointer, we noticed that we were getting snipe on the last 3” of the board. It was a pretty significant, so we began adjusting the outfeed table to fix it. The only way we can get it to be at an acceptable level is by raising the outfeed table all the way to its max limit, its completely topped out. This is not at all what we have had to do on past jointers and was wondering if this was normal due to the parallelogram nature of the machine or something about using the helical cutting heads, both of which are new to us. Thanks in advance for the help.

The outfeed table and the cutters at TDC (top dead center) should be at the same height.
Is this not the case with the new jointer.

There are only two adjustment points to look at for this: The outfeed table or the blade set height.

If they are co-planer at maximum adjustment then all is well.
If Maximum adjustment still leaves it short, then look at setting the blade height lower. My jointer has a small magnetic tool that rests on the spindle head to set the blade at the optimal height. This is usually somewhere near the center of the outfeed adjustment range.

The outfeed table on my Craftsman jointer is at max height, is also perfectly aligned with my blades and works like a dream.

You might need to lower the knives if the out feed table is topped out and you still need a little more adjustment. You will also want to check the setting on each knife (both ends of the knife) to make sure they are properly adjusted. The factory just throws them in and we assume they are adjusted when they are not. Good luck.
