Problems with DeWalt 734 thickness plane
Hello All! I have a Dewalt 734 thickness planer which I am having a small problem with. As I am planing a board their is always a small high spot on the lumber, as it comes out of the finish side. And to make matters worse sometimes high spot is brown, like a burn. Has anyone had his problem. I would be thankful for any and all help I can get.
Thanks Jack

when you say small how small? And what shape? Is it a long strait hight spot running the whole length of the board? Or does it go the other direction?
More details please.
Thanks for your quick reply wiskytango. The problem seems to be coming from the center of the planer, I would estimate the high spot is approx. 3/16 of a inch wide and just maybe 1/8 of an inch high and it goes the full length of the board. Hope that helps

It sounds as if you have a nick in the blades. Have you checked for that?
Don
where about in Utah are you located?
I would say a big nick in the blade. It's time for a new set sorry to say. always look out for nails or other metal imbedded in the lumber you are working. Also don't plain wood with old paint build up, it will mask the nails even though you think you got them all.

Practically neighbors,
I agree with Don
Sounds like you have a nick in your blades. Just to confirm the hight spot is a ridge that runs lengthwise down the boards full length, Time for new blades or I think the DeWalts are reversible.
Well that may be so but I just but new blades on no to long ago, besides why is the mark brown or burnt.

It's burnt because the blades, where they are nicked, are no longer sharp, so they are not cutting -- just flailing the wood away.
It's a nick. Doesn't matter how new they are. In fact, Murphy's law dictates that you will get a nick within 10 minutes of installing new blades, and not for months & months thereafter.
With a spot this large, you should be able to see the problem with the blades just by raising the head and holding a straight edge up to them. (Unplug first.) Give it a shot -- see for yourself.

I'm not familiar with DeWalt, but on a lot of other planers, you can shift one of the knives left or right a bit; this places a "good" part of the knife over the spot where the nicked knife didn't remove wood and left a ridge.
Or, if the knives are two-sided, simply flip one knife over (you only need to do this to one; save the other(s) for the inevitable nick that will come very shortly).
Thanks Kreuzie good idea, never thought of that
Thank's again Jack
I have this exact machine and i am not sure you can do this. The blades sit on little pegs and there doesn't seem to be much wiggle room. But I never really tried either. Would be interested in knowing though if anyone has done this.
