Planer blade sharpening jig,first year woodworking projects,aircraft cabin design software - How to DIY
The problem with sharpening disposable blades is that they are keyed and can't be adjusted to compensate for material lost in the sharpening process.
I was inspired by Chip, and purchased a friable wheel and ground ALL my blades in a setup on the table saw.
I bought the Deulen jig in Atlanta because it was a good idea, very well made and I really liked the Deulens. I finally had a chance to try out the Deulen jig that Tom Walz sent me pursuant to his offer above, and I have to say that I was pretty impressed with it. The most difficult part of sharpening my blades (all of which were knicked and very dull) was flattening the back side.
Second, my guess is that the next time I need to sharpen these blades, it will require a lot more effort to remove knicks. After your purchase unzip the file and open Planer-Jointer-Knife-Jig.html with your browser. If you use a square to align the blade, you need to bend over in front of the saw and squint for light in between the blade and the square or use feeler gauges (either way this method is a PITA). Very subtle movements in the angle of the blade produce huge movements in the dial (very sensitive). I've sharpened 3 sets for the jointer and going to do 2-3 sets for the 13 inch planer after I finnish with the girls door.
This holds the blades in place while you turn the jig upside down and sharpen the blades on sandpaper over glass. I made a hard maple block to hold blades at the exact angle for passing under a white, friable cup wheel in the drill press. There was some because my honing wasn't perfect but I found that the blade bevel is wide enough to do a pretty fair job, far better than a commercially sharpened blade and its not difficult with an 8" jointer knife.
