First and foremost, my HUGE thanks goes to fellow LJ’er, WoodShaver. His plans were perfectly made and easy to follow – thanks!

I was sick and tired of throwing away 30 bucks at a time (or even more) when ever my planer blades got dull or I put just a tiny nick into one. While the blades on my 13” Rigid Planer are labeled as “Disposable” and “Non-Sharpenable” I KNEW these things could be sharpened!

Then I saw Tony’s post and I HAD to make one of these.

Mine consists of a solid, very dry piece of red oak. Following Tony’s image he posted, I was easily able to make the cuts needed – my suggestion is to cut two blanks – one tiny and one the size you need so you can practice your cuts on the tiny one first. All the cuts, btw, are done on a table saw and are very safe to make.

Then I had to tap 12 holes at 45 degree angles and thread screws to be used to secure the blades. After that it was just a quick matter of rounding over the handle part and sanding.

I used sand paper glued to glass as suggested and since my planer uses three blades, in order to get all blades even, I sharpened two complete sets at one time.

The two pieces of red oak in pic six shows the difference – the piece on the left used blades that were dulled after normal use. The one on the right was after sharpening. It barely needs sanding.

Thanks again Tony!!!!

Pretty cool Bob. You’ve got the right idea of sharpening two sets at once to keep them even.

I just put a new set of blades in yesterday and was looking at my old ones thinking I can’t just throw them away.

Going to have to make one of these!

Looks like it’d work very well

Looks good! And it’s good timing. I’m about to pull my blades and was going to try and find a place that would sharpen them. I’ll make this jig instead!
