I have a dewalt 12.5” planer that I love but, I changed blades recenly and now I have a bad chatter when I try to run a board through it. I checked the blades and one of them was out by a 1/16” so I got them both at exactly the same but it still chatters. Any ideas?

I also have a DeWalt planer.
I think you have to be very precise. A sixteenth is a very large misalignment, and even a couple of thousandths will give you chatter.
But I wonder if there is something else that happened during the blade replacement procedure?
I don’t know what is doing it, but I’d start with the blades, using an accurate dial indicator or a digital caliper and make very sure that all the blades are lined up from end to end and in their relationship to one another.
If you get it dead on and it still chatters, I’d want to see other things looked at, such as the feed rollers.

I have the same planer. I find that if I let the board sit on the in feed table, putting no down ward pressure on the board, and when it comes out the out feed side I only support it lightly as it feeds out that I get virtually no
snipe. Another words I let the in feed out feed table, and the rollers do the work. That has worked very well
for me at producing virtually no snipe.

I would start with rechecking everything to make sure they are seated properly. Use mineral spirits and thouroughly clean the rollers and make sure there is nothing (wood chips) you are missing.Maybe make sure the chain is lubed.
