I am making a butcher block and started ripping the maple for it this morning and realized that the blade was getting rather dull and needed a quick solution . I remembered buying these diamond sharpening plates and thought I could make a jig by using the fine grit plate .

The jig I made is very simple and easy to make and use .
A piece of 2×4 cut at an angle(20 DEG) with a handle and a fine grit diamond plate glued to the 2×4 wedge .

WARNING
Unplug the saw when using this jig !!!!!!!!!!!!!!

To use it I set up my sled (see here )
http://lumberjocks.com/projects/61820
and position it as seen in the pictures and clamp it to the saw table align the tooth face with the diamond plate by moving the sled for or back and raising or lowering the blade and now it is simply a matter of sliding the jig side to side along the sled fence and putting light pressure on the saw blade .
After about 10 strokes of the jig I rotate the blade one tooth and sharpen the tooth and go until I reach the first tooth mark I made with a felt marker .
To rotate the blade I made a small notch in the jig right next to the diamond plate which allows the blade to move past the jig .(pic #6)

The notch for the blade to be able to be rotated to the next tooth


What I use to clean the blade before sharpening and it works .

I am quite happy with the sharpening and the result cutting a 2” piece of maple looks pretty good .

Tomorrow I will sharpen some more blades as I am very happy with this jig and may figure something out like this for my router bit sharpening also .

Let me know what you think .

Klaus,

I had a close look at the jig and like the principle.

I use diamond stones to touch up, my jointer and thicknesser cutters no problems there at all.

I agree they work well. but I noticed they seem to lose their diamond curtting edge very easily.

I take it from the project title your regular sharpening shop closed up.

You will need to find another, as accurate grinding will eventually need to be done.

I have a small saw sharpening machine which I use on a mostly irregular basis as I cannot see that well and need to use a magnifing glass to set up for combination and cross cut angles before I even move from tooth to tooth.

This process takes quite a lot of time, setting up checking grinding the checking the as I want to ensure I am removing equal amounts of material and getting the same result on each tooth making the process long winded leaves the feeling of uncertainity as to me removing equal amounts of material.

This is it.

It has a diamond stone wheel for tungsten tips.

Setup.
Once the blade angle and pitches are set all you have to do is draw in the grinding wheel and gently resurface each tooth, then traverse it out and move to the next victim and repeat the process.

May be of interest !!

-- Regards Robert

That’s pretty fast. Diamond cuts carbide a lot faster than steel. I have a fine diamond sharpening case for router bits. I also use my dremel took with the diamond disk.

Nice job on this jig. One can never have enough shop tools/jigs to help us get where we want to go with a project..

Very interesting Klaus. When I first seen the picture, I wanted to holler out: “don’t cut your diamond stone in half”

I have tried a similar set up of this and only got fair results. It works but not as good as having them resharpened.
You have a interesting set up and I will try this soon as my blade life is nearing its end. This could save some dollars in the future. Unique idea Klaus.

That is using the head to get through in a pinch. I would be afraid for my accuracy. But I will still give it a try on some blades I have saved to get sharpened later. Thanks for the idea.

I use diamond stones for sharpening steel, I wonder if the harder carbide could damage the diamond stone? (I realize that diamond is harder than carbide, but the binding agent that holds the diamond to the base might not be)

WoodNsawdust, the binding agent is even softer. If they could find a binding agent that was harder than diamond or carbide, they would use that instead of the carbide. This is a good idea, those sets of three diamond stones are $10 or cheaper at HF, and one should last through several saw blades at least. Though I’m wondering if you could get even better results using a higher grit DMT or EZE lap plate. You’d have to find one of the thin ones.

That is a great idea. I have a commercial carbide sharpener, but it takes more time to set up. I think I will try it.

Good thinking… should work on my sled. One of my blades needs it! Time for a trip to Harbor Freight for some new Diamond Stones!
