Thread: Did I lap properly?

In the third picture I can't really tell about the bottom-right corner. If it's like the other corners/edges, it looks good to me.

you may want to ease over the vertical edges as well. Helps to prevent those little chips

Lovely pictures of a stone with marvelously eased edges; I can only assume that its flatness is also a picture of perfection.

great job welcome to fun hobby.

The razor's edge passes over the long sides of the hone, that's why you bevel those edges. Since the razor should never reach the ends of the hone (the short sides), there is no need to bevel those edges unless you prefer it aesthetically.

I realize when doing a rolling x a rounded edge is nice.

However there is nothing wrong with using the short dimension to hone on as well(using the whole stone rather than just the usual path)

As well, the edges need to be eased over to prevent chipping and eliminate the risk of cutting yourself on the sharp edges

I'm a big fan of rounding all the corners. I find myself getting (stupidly) complacent with my razors sometimes, and find myself thinking, "I should have folded that and set it down before I ...". The less opportunity you have to screw up your blades, the better luck you will have.

hey guys, quick question... I have an 4k/8k norton and I have norton's lapping stone. I've gone through the pencil matrix thing several times and yet my razor still doesn't seem to be lying flat on the surface. So I assume either the hone isn't actually flat, the razor isn't straight or both?

My lapping process is:
1) draw the pencil matrix
2) hold the lapping stone in my left hand, motionless over the sink
3) hold the hone in my right hand
4) place the hone flat against the lapping stone and move it in smallish circles until the pencil matrix is gone, occassionly rinsing the residue off under water.
4.1) repeat if neccessary.

needless to say my razor won't even cut arm hare what am I doing wrong?

Your stones should be sitting on a flat hard surface like a counter top so they are flat while you're rubbing the top stone into the stone underneath. That's sounds like a major issue with your lapping to me. Your hands are probably moving even slightly and contouring the stone a little bit. There is a lapping 101 wiki on this site.

Thanks Disburden, but that's where I'm confused. In the wiki is shows him holding his other stone in his left hand and the other hone in his right and moving in circles like I was doing.

Quote from the Hone Lapping 101 wiki:

"To use my DMT hones for flattening, I usually hold the DMT in my left hand and the hone in my right. I make circles with the hones under a stream of running water in the sink. "
