Not sure if I am posting in the right forum, but I am a newbie and

have a question about my planer. It leaves marks(ridges) in the wood and I’m not sure about the best way to remove them. I’ve tried sanding it out with my orbital sander and it is hard to keep the wood flat. Does anyone have any advice on the best way to do this?

Also, can my planer be adjusted to eliminate this? Thanks in advance for any suggestions!

Its typical for a planer to leave marks. Best way to get rid of them is a smoothing plane. They can of course be sanded out as well.

Yep, pretty typical to have mill marks from a planer or a jointer. Yours seem a bit extreme though. I’d check your planer knives to see if they are set correctly. Here’s a helpful video

For your wood in the picture
+1 for smoothing plane
+1 for sanding
You could try a cabinet/card scraper as well

What Kd said; those seem extreme. Buy and install a new set of blade if you haven’t already. You will be amazed.

Try a sharper set of blades. I like using cabinet scrapers instead of sand paper to smooth out the surface. Once you learn how to sharpen a cabinet scraper you’ll find this to be a great set of tools instead of sandpaper and will save you money. Here’s a link and there’s tons of info out there on how sharpen and use them

They are pretty new blades, maybe 50 BF through them. I bought 2 sets of blades from globaltooling.com I made a homemade jig to set the blade height and wonder if that isn’t my problem. I bought the planer last Fall(Belsaw) and it is 20+ years old, is there anything that could be worn out to cause this? I’ve checked all the bearings and they seem fine.

It would be very helpful to know what planer you are using, the depth of cut, the speed through the planer and anything else you can describe.

Is this a new planer? Have you always had this problem?

Is it the full length and width of the board?

I have two planers and never encountered anything near that bad.

Oliver, I bought a set of scrapers and am still trying to learn to get a good burr on them.

UKCat....As stated above, I think you should check your knives to see if they are set correctly. One knive might be a thousandths off compared to the other (two knife cutterhead) or others (three knive cutterhead)...The video is helpful to set planer knives….that is where I’d try if it was fine before you changed the knives …..good luck

I’ve got what sounds like the same planer as you do. It leave the typical scalloping from a planer, but not like yours.

I was reading on my phone earlier so I didn’t see how bad it was. I’d agree with above, you should be able to get better, but you won’t get perfect.

Yeah, I wouldn’t put up with that kind of variance. I don’t get any mill marks from my planer.
It looks like the same type of scallops a jointer will leave when the knives are not set even. I would go back to the drawing board with setting your knives. Maybe one shifted while you were tightening it down.

This is what I made to set blade height. It seemed to work pretty good when I changed blades. I will check again tonight and see what I got.

Have your say...
