@Wid What did you take that one up to?
I had to call about this stone.
1 sided stone, the plan is 600 grit finish though. I do not believe I am going to burnish it unless it negatively affects my edges. I will play w it to get it to my liking and take notes as if I was new to DE and trying new blades….. thank you for the thoughtful post though. Unfortunately I’ll have to use my leathwork granite slab as a backer for my steel sheet I don’t thing the is a square foot of flat concrete around this hous.Once the stone is flat and smooth it is quick and easy to change the stone’s face. You can finish one side to 600 and the other side burnished, 1 or 2k for a nice 2 grit stone.
If it is flat and smooth, lap with 600 loose Silicon Carbide on a steel cookie sheet on a flat piece of cement floor. The stone face should be flat and smooth with a uniform mat finish. If not then you need to drop to a lower grit to remove the defect, (remove all the stone to the bottom of the defect).
Try finishing a razor on the loose 600 grit and test shave. Then re-finish on a new sheet of 600 Wet & Dry on the cookie sheet on the floor, using your body weight.
600 W&D is a bit finer than loose silicon carbide. Hone a razor on the 600 face, if you like it, you are golden. Or you can run up through the grits to 2k to polish the face and try an edge at each grit. If you don’t like a grit finish you can move up in grit or drop back to 600.
To burnish, I use a large antique carbon steel cleaver, a large cleaver, kitchen knife or plane blade allows you to grip the tool and apply pressure with your body weight, again work on the floor.
Work about a ½ to ¾ inch at a time back and forth with pressure, you will feel the stone smooth out where it is being worked. Overlap your strokes until you have covered the whole surface.
Repeat the burnishing process and see if the stone feels smoother. The stone face will become smoother with use, also slower and polish finer. This is where a 2 grit, 600 and finer or burnished stone faces comes in handy. Each stone is a bit different, and a lot will depend on the quality of finish on the razor, and hardness of the steel when you jump to the Ark.
A good Ark is a bit biting keen without being harsh. You can maintain an edge on an Ark for a long time.
Yeah. I have a few found in the wild type stones, and usually carve out a wooden base to match the shape of the stone.It does not, have to use a towel under the left side to keep it stable. Will probably make a form fit box for it with cast latex after I get it lapped out
I had to make a wooden base with little leather risers inside that keep the stone level for my primitive translucent from Dan. It was kind of a pain to make but not too bad. I had to smooth it some with a diamond plate but it was rocking in the base without the leather risers. I've thought about selling it but it's 4½"x 5½" so it's perfect for plane irons and chisels..I keep wanting a Dans primitive translucent or Hard black... but I've got that monster I won on EBay and It doesn't get used enough I could justify another...
As cool as they look... a nice square cut stone is just so much easier to use.
Then again I haven't made a nice base like Legion; I just rest it on a coiled towel or something when using it.
