I’m in between projects at the moment. This is a rare time for me. Usually I have more than one going. I decided to take the time now that I’ve finished the drill press table to go ahead and do both some shop cleanup, and some tool tuneups. First up is flipping the knives in my Dewalt 735. This planer has indexable insert knives, and I’ve never flipped them before. I’ve probably run a few thousand board feet through the original set. While it still cuts fairly well, there’s definitely once place where there’s a small seam in my boards due to hitting what I think may have been a hard knot or a small staple or nail. Not such an issue on the workbench, but now that I’m moving on, I decided wear and tear I’ve gotten my $20 worth out of this side of the blades.
I vacuumed and blew the planer out with compressed air. Looks quite clean!
Using the provided tool, I unscrewed the 4 allen screws and the lid lifts off to show you the dust shroud.
The 3 red T bolts are easily unscrewed by hand, showing you the planer head.
You unscrew the 8 or 9 allen bolts from the blade hold down. ( I figured out before this that I would have a hard time knowing which side of the blades were dull or sharp, so I actually rotated the head around, and put some marks from a black sharpie on the ‘dull’ side of each reversible blade.)
Then you lift off the black metal blade hold down, and you can see the blade itself.
Then you can use the backside of the Allen wrench tool, which contains magnets, to lift out the blade. I took the time to wipe down (carefully! The blade is sharp! the accumulated sawdust and gunk that had worked itself into the blade and hold down cover over the last year or two. Here you can see the sharpie marks reminding which side of the blade is dull.
I then went back and cleaned the blade-less planar head of accumulated dust and gunk. I gave the whole thing a good vacuuming out, just for the sake of being complete.
Assembly is just the same as the teardown, but in reverse. I fired it back up and put a light pass on some Sipo. Good as new!
