How big of a deal is it to sharpen the jointer and planer knives?

If you have a way to get them perfectly straight, it wouldn't be too difficult.

Personally, I just take mine to a local guy who has the equipment to sharpen them for me. He does it cheaper than I could buy equipment to do it myself.

If you have/get this - http://www.shopsmith.com/ownersite/cata ... rpener.htm -and a conical disk with sticky backed sandpaper for that disk- it is a breeze to sharpen both planer and jointer blades.

I have done it several times. Just follow the simple instructions and bingo!! You're sharp!

The sandpaper for the conical disk is different than the paper for the flat disk.

Yes, I agree. I have this setup on my custom Mark V Power Station with a 500 main table that I am keeping set up for knife sharpening. Contact me if you cannot find anyone to sharpen your planer or joiner knives.

My planer knives need sharpening.
I think I am going to try making a jig like this one I found on ibuildit.ca.

Sound good, thanks all

I use a block of wood with a snug fitting groove cut in it at the proper angle to hold the blade. If it dosen't fit tight you wedge it or drill some holes on either side for screws to clamp the blade in place.

I mount a grind stone to the headstock and set the table height so the blade very lightly touches the stone. Make several passes and raise the table again. Grind all the blades at each position before adjusting the table height. Repeat until the nicks are removed and then hone the edge on a flat surface. Sand paper on plate glass for example.

This is the only way I've ever done it.

Next time I do this I should take some photos.

I built a simple fixture (a derivative of one in the SS manual) that works with the conical sanding disk. I posted pictures and a description about 8 months ago. Works great and very easy to use.
