I bought a JET jointer over the weekend, the 6” with the long bed. It’s a solid machine, flat bed and fence, works great so far. My first piece through it was a small piece of poplar, just to check the setup, went fine, really smooth surface. Then I moved on to cherry, 2 pieces about 2 feet long 5 1/2 ” wide that I’m using for a jewelry box. The blades got nicked in 2 spots almost immediately. The wood was clean, directly from the lumberyard, the depth of cut was about 1/64” and the feed rate was very reasonable, with the grain in the proper direction.
Does this sound right to you ? Do you get nicks on jointer blades that easily ?

Doesn’t sound right to me. I don’t know what to tell you.

You can take one of your blades and move it slightly to the left or right to get rid of the marks on
your lumber.

Gary,
Doesn’t sound right to me either. The blades were obviously factory sharp. Anyways, thanks for the tip.

The blades will get nicks in them over time but should not have done it this quickly. If there was any debris- dirt glue etc.- that may cause a nick (I know about glue and nicked blades). And one of my planer blades have developed a nick but this is strictly from use after planing a few hundred feet of cherry and maple.

Gary is right about loosening the set screws and offsetting the nicked blade a little to let the other blades compensate for the nick.

Bummer.

Scott,
I agree, nicks happen, just not so quickly. I researched a bit more on the net and found this:

Sounds like I am not alone here. The blades don’t seem to be of very good quality, but since they are the quick setting kind, I can’t replace them with standard knives.
Oh well, live and learn.

Sometimes you can set a board down, & unknowingly transfer a piece of grit to its surface.

I also shift a blade over to eliminate the groove.

Hi BANick.

As Dick pointed out it fairly easy to pick up some debris and feed it past your shinny new blades.

Blades always get nicked, sometimes quickly, sometimes after a while of use. It’s a crap shoot as far as that goes.

It’s true though, that blade quality plays a large part here.

Good luck with the new machine.

Lee

Even a knot will nick a blade. Also, just because the lumber was “fresh” from the yard, it doesnt mean there wasn’t something embedded. Like the time my new planer knives found a broken off staple in the wood.

I guess because I’m a Type “A” person I keep a second set of knives for my planer.
And I have, once or twice, replaced just one blade that was nicked.

One blade? Yup, the other 2 weren’t nicked so it had to be the blade, not some foreign object.

Heck – if you just got the tool I’d make a fuss to the store you bough from and see what they are willing to do. You can’t complain about nicked knives a few weeks into owning them but if it’s after 2 boards you might have gotten a poorly manufactured set…machined parts sometimes have flaws.

What folks have said here are true, lots of things will knick your blades but it shouldn’t be this soon into the game.

BANick, check out the tool reviews. I posted a company that sells quality blades at a very reasonable price.

Had a similar experience once. Checked the edges of the board, ran it thru the jointer only to discover the blades were nicked. I found a piece of a staple, used to hold the UPC sticker, in the end of the board. Now I check all 4 edges.

I guess nicked blades are more common than I thought. I installed a new set of blades on my jointer that I purchased from Inifinity (carbide). I thought if I spent more money on higher end blades they wouldn’t nick as fast. Wrong. Within a couple of months, one of the new blades was nicked.

I also bought a new planer recently. I have hardly used it, and I’ve got a nick in a blade. It’s pretty hard to inspect rough cut wood for any specs of grit that could be lodged in the wood. As has already been pointed out, a “fresh” piece of wood can still have foreign material in it, which can nick a blade pretty quick. I agree with Lee, that sometimes you’re just “lucky” to not nick a blade as fast. It is bummer though to damage a blade so soon after you get a new machine or install some newly sharpened knives.
