Question on Lapping Film Stone?

[OkieStubble]

I went to a stone cutter's yard the other day and asked for a scrap piece of Polished granite from counter making. The owner was kind enough to bring me two pieces. Both pieces were 1 1/8 inches thick. 1 piece was 5"x 5" squared and the other was 5"x8". The top side was polished and smooth I can see my reflection in them. However, the very leading edges of the stones where the polished top side meets the unpolished sides has some what of a rough edge.

Does anyone have any advice how I can smooth the edges? The lapping film will meet this edge and I feel like it's not smooth enough.

Just take some sandpaper 220grit or whatever you have and lay it on a flat surface and drag the edge over it to slightly round or bevel it until it meet your approval. The paper can be wet or dry but wet is probably easier.

+1. Try wrapping the paper around a piece of cork, or something like that. A sanding block might make it easier to get a more even bevel on the corners. It does not need to be rounded much, just take the sharpness off.

I would try to find something longer, though. Those will work, but it is nice to be able to use longer strokes. I use a 12 x 4 polished marble edge tile from Home Depot. You can go to Lowe's and they will cut a 12 x 12 tile in half or thirds for you, total cost less than $5. One of the advantages of film is that for very little coin, you can have a very big honing surface. Don't give that up without a fight.

Slash, How do you keep from hitting the hand you hone with from hitting the table? The reason I got the granite was because the thickness allows room for your hand when honing?

I hold my plate in hand. It allows the blade and the honing surface to find each other. But you can lay it on the edge of the table, or glue it to a piece of wood.

Not Slash but I saw this one coming when I made my setup. Cut the marble tile (I have a cheapo tile cutter) to the size of a 2x4. Glued the marble to the 2x4 with epoxy. In five minutes, I had a perfect table hone that could be used on a kitchen counter without worrying about leaving scratches.

Simple yet genius. I love this place.
