Hi all,
Over the last few years I haven't done much woodworking at all. So recently I decided a need to build a desk. I have a DeWalt DW735 planer that I've had for years and have had good luck with. I pull out the old 735, put a set of brand new blades in and start to plane some cherry. Immediately I get multiple "streaks" in the wood, running the entire length of the board. I think "Great, the blades are already nicked." I check the blades, clean everything, make sure there are no stray chips and try a couple more boards. Same thing. I flip the blades, clean everything again. Try again. Same thing... streaks.
When I tried to clean up the streaks with a sander or scraper, I notice they are not ridges as one would expect from nicked blades, but are depressions in the wood.
I run a board half way through and shut the planer off, then raised the cutter to see if I could see where the streaks are coming from. As it turns out, the streaks correspond exactly to the position of the screws that hold the blades in place. It appears the screws are rubbing the wood and making depressions in the wood. I thought perhaps I might have a defective blade that was too thick cause the screws to sit too high, but a check with digital calipers showed all three blades were thinner than the set I replaced.
Has anyone else encounter such an odd issue? If so, did you find a solution? My only ideas at this point are to try to shave a tiny bit of metal off the screw heads, but I am reluctant to do that since as I don't want to unbalance the cutter head.
Any thoughts are appreciated!
Regards,
Shannon
