Scary Sharp Jointer Knives

[Mauser712]

I've done scary-sharp before on Chisels (back when the technique was first being named on rec.woodworking), and once took it all the way to 2000 grit "Rose Paper" you can get for doing auto-body work, which left a literal mirror sheen on the sanded surface. But I'd never heard of putting sharpie on the surface, which is a great idea. I like the jig too. I've got an extra set of 12" planer knives that could use a go.

Thanks for posting this video. I got a free 12.5 inch joiner that's blades are messed up. Was wondering how to sharpen the chunks out of them, your video was the answer.

Hi, what kind of glue do you spray on the granite?

Thanks,

How about routing a shallow depression for blade alignment instead of brads. That would give support along the entire board.

@BradburyGuy Not a bad idea.  Thanks.

I made this jig yesterday to sharpen my planner blades and I am very happy with the results. I did notice I still have a few ridges in my blades from before. I'll have to figure out if I can remove them or maybe have to buy a new set of knives. Thanks for the tip/video.

@jodscho I'm glad it worked out for you. Really deep ridges are tough to remove with this method. You could try a coarser grit and see if it helps.
