I am experimenting with a used planer(Ryobi AP10) and planed some 2X8 pine lumber. I noticed small marks on the faces that I planed tonight. Here are a few pictures. Why am i getting these marks?

I have no experience planing other than what I read on the web. this was my 2nd attempt. Any help is appreciated. Thanks

Doesn’t look like a planer mark to me. Possibly something unique to that board as it appears that it’s just on that one area of the board.

Thanks for the responses.

I planed about 5 pieces, it appears on two from the same board and not on the others from the other board. So Joe you may be right.

This planer (according to the person I got from) has not been used much at all but sat around for a number of years. It was fairly rusty/dirty, I am not sure if humidity/heat would cause the blades to dull. What do I look for to determine if the blades need sharpening? Can I sharpen them or do i need to get new ones?

Corrosion can cause blades to dull, and humidity and heat both encourage corrosion.

I could be wrong, but I think if you want them sharpened you are better off paying a professional.

the blades from lowes fit the ryobi. they are the porter cable ones. I have the ap1300 and it takes those. they are only 29 bucks

I have the same planer, the blades for the ryobi tend to be a little soft so you really have to keep them sharp. I change mine regularly and love the machine. Make sure that you have the guide/jig for setting them. If you don’t search online and there are a few places that have the blades and the guides. I have three sets of knifes because I never want to be caught without a sharp set while some are out to be sharpened. You can sharpen them yourself, I just don’t have the time. The AP 10 is the original portable power planer. I real screamer, but a good little machine. I gave $40 for mine 2 years ago and love it.

Remember, planing flattens, but you still have to sand the material smooth and with some pieces, there will always be imperfections and this maybe what you are seeing. Give that sucker a good cleanup, and be careful that chips don’t get built up back inside the planer as this will really stress the motor.

You might check the pressure rollers, too. My Ridgid was doing similar things, and I found a lot of chips imbedded in the rubber rollers. A few minutes with some denatured alcohol and a rag took care of it. (BTW, don’t get anywhere near the business end of these things while they’re plugged in)

Thanks for the responses. I will take a look at the rollers and around the motor.

The blades are on sale at amazon for about $30 (Freud c600 is the brand/model number). the guide is available from there as well.

Justin: Where do you get your blades sharpened? Also I did not find anything in the manual regarding the guide? Where I can find out how to use it? Also is it absolutely necessary? The manual makes the blade replacement sound easy but they always do….

Skeeter, I am not sure that Lowes carries blades for the AP-10, at least the ones I saw were 12.5” and would not fit the AP-10. Its only 10” wide.

I have attributed it to the nature of Yellow Pine myself. Being that Yellow Pine tends to have a lot of resin/pitch in it. I changed blades and would still have the same problem on some boards. I ran different species of wood through and had no problems with blades or wood.

this does NOT seem to be caused by the planer – the marks are too distinct. remember -those blades are spinning FAST – if it would be something caused from the planer- you’d have a long scratch/mark all along the board from start to finish – not only small marks in the middle. This is true especially since you mentioned it only happened with 2 of the 5 boards you planed.

Pine does that sometimes.
