Woodworking Planer Jointer Knife Sharpening Jig

A DIY jointer/planer knife sharpening jig. Good jig for sharpening dull planer or jointer knives. Visit my site for more tips: http://www.garagewoodworks.com/
*In order to line up the brads the same distance from the front of the jig use a marking gauge to scribe a line. Place the brads in the groove created by the marking gauge and hammer them in with a tack hammer.

Hi there

Great Jig. I wonder if we can use 3/8" rigid polycarbonate sheets instead of granite ?

Is this a special type of 320 grit sandpaper and what type of spray did you used to fix it on the granite ?

Thanks

@pjibe If you are sure the polycarbonate is perfectly flat go for it. The spray adhesive is 3M Adhesive.  The sandpaper is home store wet-dry sandpaper.

Hey great demo! I was wondering I keep seeing theses pieces of granite being used for a flat surface. I currently work in a granite shop (Yes I would prefer to be in a cabinet shop but i like to eat thanks economy!) and the material all comes in 3cm or approx.1.25 inches I noticed yours is about 6cm or 2.5 inches. Is there a reason for the thickness? Or have you seen any benifits from this? Only thing I could think of would be hand clearance for something....

@squash419 I bought my granite from Woodcraft. I'm not sure why they make it as thick as they do. Increased flatness stability? Not sure.

Thanks a lot. I own three sets of planer knives because I didn't know how to sharpen them myself. I'd thought about using a method like you have here that is similar to the jig for sharpening my chisels but I never spent the time to design and implement it. Your video will save me a bunch of time.

I have the same granite block for sharpening chisels that you have.

Question: Is 320 fine enough for planer blades or do I need to go finer?

Thanks again,

Russ

@signmeupruss I get great results from going to 320 grit. I have never experimented with going to a finer grit. I also use 320 for my jointer knives and the results are great.

Before I made my jig I would send my knives off to be sharpened "professionally" and they came back looking like they were sharpened on pavement. 320 grit is a huge improvement.

or maybe just dead weight 8~$

Not bad at all. Hey jointer blades are expensive to replace. Thanks for the great tip. Thats is a useful gig. john PS recommend getting the mic closer to the presenter. thx

Good info . I made this out of aluminum with slight variations. two bearings and a rabbitt instead of locator pins . The drawing I created is in the google sketchup library under "sharpening jigs" for anyone thinking of building this. Thanks. It worked really well
