Topic tags/keywords: question jointer blade sharpening

I found a nail in some old deck boards I am re-purposing. Not surprisingly, it did a number on my jointer blades. They all kind of look like the above picture. Are they salvageable, or should I just forget it and get a replacement set?

That looks pretty bad. It would require removing quite a bit of metal to get back to a clean edge. I think I would invest in a new set, right after I invested in a metal detector. You can get one of those really cheap at Harbor Freight.

It doesn’t look too bad considering the damage is close to the end of the blade. Sharpen it and move the fence past the damage area.

Find someone with a surface grinder or a sharpening service. If it is just a surface grinder then they will need a jig to hold the knives at 45. Personally I dont think it is a lost cause. 1/16 would do them a world of good.

Metal detector is a good idea I have been putting off. I went ahead and ordered a replacement set, but I will drop these off at the local Woodcraft to have their sharpening service take a look. If there is a chance to save them it would be nice to have a spare set.

Yep, the spare set is a big plus. Those may be salvageable, at least one sharpening.

They should be able to remove that nick as long as the knives are wide enough to allow it (ie: haven’t been sharpened a bunch already). As for the metal detector, the HF handheld works great and can be had for about $13.

Cheers,
Brad

PS: They also work great as a pinpointer when used in conjunction with a regular metal detector.

At work, I normally have three sets for machines in every day use. That way I can have one set in the machine, one set on the shelf, and one set at the sharpening service.

But I don’t use these things that much at home, so I’m lucky if I have one good set….

Replace. Average quality blades are cheaper than a resharpening, and the old ones can be recycled.

For the short term, you could use it as is and use your hand plane to remove the ridges.

The chip looks pretty bad. You will need to evaluate cost of sharpening verses buying a new set.

If mine they’d be junk, in general jointer knives are pretty cheap.

Yep, that’s the one I bought and I can recommend it. It gets the job done just fine.

My HF metal detector has saved me several times.

Well, gentlemen, here’s the end of this story. I bought a new set of blades, and had the damaged ones sent out for grinding and sharpening. The old blades came back looking like new, and they only charged me an Abraham! I did also get one of those Harbor Freight wands with my 20% coupon. Hopefully that will prevent some future incidents. Thanks to everyone for your input.
