no previous part Part 1 of DMT Sharpening Station series Part 2: The Reveal »

Over the past year I have been collecting DMT DiaSharp stones one at a time. This is what have:

Extra-Extra Coarse (120x)
Extra Coarse (220x)
Fine (600x)
Extra Fine (1200x)
Extra-Extra Fine (8000x)

Now that I have a full collection I decided to make a sharpening station for them. Up to now they have all been sitting on the bench or where ever else they wouldn’t be in the way. My goal is to have them all inset into a piece of plywood so they will always be together and accessible.

Starting out with a piece of 3/4” plywood I marked where the stones will be.

Using my little router I cleared out most of the waste. I finished with a final depth of 1/4”. Once I cleaned all the dust off myself I finished clearing the waste out with my chisel.

Here are the stones sitting in their new home. They fit nice and snug.

I found they were a little hard to get back out so I cut a little finger notch to get a better grip.

Now to dress it up a bit I surrounded it with some poplar trim. Once the glue dries I will plane it up nice leaving a little lip along the top to keep all the sharpening goo on the board and not all over the bench.

To keep it from sliding all over the place I picked up a package of 2-3/4” Grip Discs used on Lee Valleys Bench Pucks.

I haven’t decided on the finish yet. I have it narrowed down to either some water based poly or some leftover melamine paint left over from a previous project. Right now I’m leaning towards the paint.

A nice touch might be burning the coarseness number under each stone.

I like these simple and practical projects.

Thanks, that’s a great idea. I don’t have anything to burn them in but I could carve or stamp the grits under the stones

they are going to be wet, so use a water proof coating. I also prop mine up when not in use so underneath can dry.

I’m leaving the little rubber feet on the stones so there is a bit of an air gap underneath and should keep the bottoms drier.

The melamine paint is basically liquid plastic so it might be waterproof enough as long as I’m not leaving it submerged.

One thing I’ve always wondered about with these setups… do you take the stones out to lap the back, or how do you go about that? I understand that once it’s done you only have to knock the burr off, but still.

I like it. I’ve got Duo-Sharps, which are double sided right now. Have an EZE-Lap, and thinking about switching the Duo-Sharps out for all Eze-Laps, and making something like this. Nice work

Sweet setup Greg.

I was actually wondering the same thing before I started Mos. I’m not sure how others go about lapping the backs but I plan on taking the stones out.

An excellent idea and it should be very easy to use. The only problem is the dirty water. Maybe laminating some kitchen counter material onto the top with contact glue would be a better solution than paint.
