Topic tags/keywords: planer damaged blade

I started a project. I’m making a cedar bench glider. I did not want to make it out of the 2×4 dimensions in the plans. I thought it would look better if I planed the lumber down to 1.25”.

I checked and pulled some staples from the lumber. I started planing it down, (DW 735). Taking my time, no hurry. I noticed a ridge along the left side. Unfortunate, but easily avoidable. Then I noticed a second ridge a few inches in from the left side. Before a realized it I had 4 ridges across the blade. This didn’t make sense. I stopped and flipped the blades. Then i reexamined the wood. There it was. A ridge that started halfway down the length of the board. I dug out a small pebble. It was not yanked out by the blade, but rather pushed deeper so it could nick a different part of the blade on the next pass.

Maybe if I was taking a deeper cut it might have pulled out only nicking one spot. Oh well. Now I know how to flip the blades.

That sucks. Can you flip one or two blades back so that all three don’t have identical nicks?

If you get a nick, and your blades are still sharp, you can slide one or more blades to the side to overlap the nicks. It doesn’t always work, but may help you in the future.

Ouch!! My “shop” is also our garage, and to the extent possible i don’t let any lumber hit the floor for that very reason.

Can you slide the blades laterally at all on the DW735 (or 734)? I have the DW734 and my recollection is that there wasn’t much wiggle room, but I haven’t actually tried to reposition them yet.

There is room to move the blades laterally. The nicks were about a sixteenth wide. I probably could have moved two of the blades, but I decided to flip them and get back to the project.

I have the 734 and was able to move one blade to the left and one to the right while leaving one alone and the problem was solved (very small nicks). The lateral movement isn’t much though, if you had deep nicks you might only be able to make them smaller instead of eliminating them.

Yea, small pebbles and ever small specks of sand you can hardly see with nick blades. I too have be very careful not drop stock on the shop floor. I have a gravel yard (see picture) and sand and small pebbles get tracked into the shop all the time. Especially when I occasionally drive my truck inside.

Seems like I always have nicked knives. I have learned it’s a fact of life for me. However a planer is a dimensioning tool, not a finishing machine. Wood coming off the planer is not ready for finishing anyway and needs to be scraped or sanded anyway. The scraping and or sanding gets rid of the ridges so I have leaned not to be overly concerned about the ridges.

Been there with pallet wood. Now that I have a thickness sander, it doesn’t affect me as much. A sanding block should actually take care of a high stripe.
