So, I’ve been quite frustrated for some time. I would have everything square, then I would go to assembly and suddenly nothing would line up. This plagued me through two projects.
Then, I’m working on some bed posts and I noticed that my Dewalt 734 planer seemed to struggle when I moved a board to one side (trying to find a fresh spot on the knives). So I move back to the other side, and the rollers will barely grab the stock. I check for square and sure enough, out of square. So I unplug it and stick a gauge block between the knives and table and run the knives down until they just kiss the block. I run the block across to the other side… crap, one side is 1/16” high.
My problem, I just assumed that my planer knives were parallel to the table. And I’m left handed, so every time I checked thickness I always checked the left side of the board. So not only were my boards not square, they were not to dimension either.
I did my research on the interwebs and I couldn’t find anything other than, “I had that problem. They will recalibrate it if you take it into a shop.” I’m sure they would, but looking at the thing there isn’t much that can affect the “levelity” of the knives. It’s just two screws. So I flipped the planer over, and here is why I’m writing this with such enthusiasm… it’s just a chain and a couple sprockets.
So, if YOU have a Dewalt 734, and you are not getting consistent thickness across the knives, here’s the easy fix;
1. Unplug it
Hope this helps someone.
