Topic tags/keywords: powermatic15 planer newblades gougemarks walnut

Hello everyone, I just did a maintenance on my powermatic 15 planer. I also replaced the blades with 3 new ones. I put a board through it and it’s leaving gouge marks in the wood the entire length of the board. Same look you get when there are dings in the blades. Again… the blades are brand new and I did recheck them.

Need pictures of defect to comment on possibilities?

When you installed the new blades did you check the in/out feed roller heights, and chip breaker height?

The PM15 has segmented in-feed roller. If cut depth is too shallow, it will leave horizontal lines down the board?

If you dust collection system clogged? If sawdust gets pressed into wood on exit with solid metal outfeed roller, it can leave gouges that look like blade marks?

So many possibilities, need pictures, and more information to help.

Best Luck.

If it is dents from the rollers or saw dust under the rollers as CK mentions, wetting it may fix it.

I will send pics along in the morning. I did look at chip breaker. I have never adjusted it and have never had an issue although it does appear to be crooked from what I can see which means I will have to make a stop block per directions. I was hoping for an easy fix but that’s usually not the case for me. Well I really appreciate the feedback. I will send the pics. Thanks.

The factory gauge block in manual is very frustrating to use.
Try making one of these instead: DIY Rotocator

Best Luck.

Strange, are the bolts/screws tightened down all the way, or somehow protruding?

I’ve done a pretty thorough inspection but It won’t hurt to check again.

The double scratch lines in middle could be result if one of gib bolts was dragging on two corners, while rest only drag on one corner.
Did the gib bar lift while you tightening down one of the blades?
They should be below the circumference of the cutter head.

Would have to have a serious interference issue with in-feed side parts of planer to make those lines, plus you would hear it dragging. Has to be related to cutter head.

Cheers!

Unfortunately the gib nuts are not the issue. None of the anti-kickback fingers are stuck either. It is obvious that something is dragging on the board. Nothing is noticeable yet.

I figured you had, if you lower the table all the way (or close), unplug the machine, and manually turn the cutter head, do you see anything protruding? Certainly doesn’t look like the infeed roller marks. I have a Byrd helical in my PM Model 15, and haven’t had this particular issue. Haven’t done much adjusting either on my planer.

Nothing is protruding. This is a mystery to say the least. I’m going to run a new board through. It’s possible there was a wood chip caught in the cutter head or something.

Measure the distance in between the drag marks and then start comparing them to anything on the head.
Something should show up matching them.
