Planer Blade Sharpening

[Dan Hahr]

I made a jig to sharpen my planer and jointer knives. I ran two slots in stable 8/4 stock at approximately 43 degrees. That way, I only hit the very edge with the sandpaper. Three knives would be too hard to keep in the same plane. It results in a slightly blunter angle but it works just fine. They get razor sharp. I think at 45 degrees, it would take forever to get the bevel completely ground

My planer has reversible blades. When I bought it I got extra blades. I just checked and 12.5" HSS reversible blades sell for around $30. Given the prices of sharpening services or sharpening systems, wouldn't it be more practical just to replace them? That way you also avoid balanceing issues, etc. I did not notice the details about the OP's planer, perhaps its blades are much more expensive.

When I owned a jointer and planer that used regular knives, I always had a spare set.

That way I could replace them as required and have no downtime.

Then I would take the dull set to the sharpening company............Regards, Rod.
