Default Diamond Discs for Worksharp 3000

I thought I would start this new thread on a continuation of the discussion on the Worksharp 3000 and diamond discs.

Thanks to Bill @schnewj , and his Post # 41, p.5, Router Forums - Router and Woodworking Discussion Community

And all the research Bill did to find a way to do the diamonds discs, that used to try this method.

1, cut some 6"X6" pieces of 1/2" MDF.
2. Drill hole in center and cut rounds on band saw, a brad point worked better for the hole than the forstner bit.
3.I used the same jig to sand the edges on the oscillating sander.

4. Layed a MDF disc on top of the rubber PVA backed magnetic disc and marked the hole location, then drilled them wit a 1/2" brad point bit.
5.Peeled the backing sheet off the magnetic disc and cut a short 1/2" dowel to guide it onto the MDF disc. When both sides were attached, clamp it in the vise to press the disc contact adhesive to the MDF good and tight.
\6. Remove from vise and insert the short dowel into the hole to guide the Diamond coated steel disc into place.

Do this to all the discs both sides and you are good to go.

Sharpening:

I made up a 180/260, 360/600, 1200/3000, Also have a 60, 80, 120, discs which I may make up later, I will have to order more Macnetic PCA discs tho.

First thing I found was that the retaining bolt and Knob on the WS 3000 was too short for the new thicker discs. So I had to make a new longer one with a jig knob I had from Peachtree.

The sharpening went very good, it is 50% faster than the sanding discs gave excellent results. less pressure is required on the disc, instead of 10 plunges and retractions, it was 5.

I did put the 3600 WS disc in to get a little more polish at the end.
Then I hand drew the chisel accross a smooth leather strop w/o any stropping solution and the improved the polish.

These are sharp tools ,folks. Thanks to Bill Scheider and all his excellent research. a real winner.

I wondered how this worked using the diamond discs on the Worksharp 3000.

Nice job Herb! About how much was the additional cost to bring it up to this level of excellence?

Herb that is pretty neat. But then we expect that from you.

Fantastic write-up Herb.

I, too, found that the hold down know was a little short, however, there is enough engagement that the original holds. Due to the rotation of the disc, the knob will tighten itself and will not loosen. I may make up one similar to what you did, but I've been lazy...

After using these plates for a while, I have found that the 3600 grit diamond plate has had a groove worn in one spot. The rest of the plate surface is fine, but the higher grits may not last for this application. The rest of the plate is still very usable for topside use.

The question was asked as to how much this costs. I'll refer you back to the original post for the set-up (http://www.routerforums.com/tools-wo...rp-3000-a.html). Basically, the DMT set-up is between $60-80. If you buy the mag plates and the diamond plates from the link source, the same set-up is roughly $35-40. This is for a two plate set-up. I suggest that you order five or more diamond plates at a time. The shipping cost is the same after five plates.

The diamond plates are true 6" plates. They are 1/10" bigger then the WS3000 glass discs...they work fine with no clearance issues.

I bought two additional glass discs off of eBay and applied the PSA backed magnet material. I then ran an X-acto knife around the disc to trim off the excess that was overhanging. I suggest that you do this, so, that, the magnetic material doesn't get snagged on something and get peeled back.

I have been meaning to cut out some MDF discs to try. I picked up the material the weekend before last, but have been "under the weather" (Springtime allergies). I plan on charging the MDF with buffing compound to act as a strop. I may even see about getting a piece of leather and gluing it to the MDF to make my own leather strop. Lots of experimenting to do, yet!

The whole downside to the WS3000 system is that it will not accept wider (2") iron. These have to be done on the top of the Disc. If you look at the stands (original linked thread) you will see stands that Desert Rat Tom and I each built. By leveling the disc to the platform, using a honing guide to maintain the desired angle, you can sharpen wider blades on the top of the disc. I have done this with great success.

Hi, sorry I missed you. I have gone to find myself, but if I return before I get back, please ask me to wait.

Thanks for all the info on this sharpening system. I too wonder where you purchased the diamond discs? and how expensive were they? I could be helpful for those who don't want to invest in the Worksharp system that is a similar DIY sharpening system was developed by Stephen Ogle using rigid diamond discs (see
). They were purchased from an eBay company called Auctiva Emporium at ' - lau***''s Emporium - Home & Garden' and are of good quality and only cost $10-$20 each depending on size.
