Thread: Question, so I don't screw up

Ok gentlemen this is what I have so far, took the edge to .0065 and did as Spazola recommended in his video, now when it comes to reading the edge, I can see definate differances, what corrections do you make, like thin bevel means more concave or taking from the spine?...Light bulb, i suppose the spine must be perfect before establishing bevel?

I just try to even things up so they look consistent. It usually takes me several iterations between hone and grinder to get the bevel and spine to look even and consistent.

I'm calling this one done, thanks for the help. 3 more and learned a ton on this one.

Your spine thickness should be set and finished before setting the bevel. Otherwise the bevel angle won't be the same on the finished razor.

I grind pretty thin before setting the bevel (0.0005" - 0.001"). But up to 0.005" would work. Then, like Bruno and Charlie said, you go back to the grinder and even things up.

The biggest help in doing the grinding, after setting the bevel, is to do it "wet". Run your grinder very slow and mist the belt with water. I add a couple drops of dish soap to the water.

I hope this helps.

Should that be "0.005" ?

This discussion is enlightening. One of the common newbie posts here is:

. . . I'm honing an old razor and the width of the
. . . bevel is uneven. What's wrong?

So modern makers have the same issues as vintage makers:

. . . How do I grind a blade to a _consistent_ 2 mils along the edge?

My hat goes off to you.

Thank you for sharing the information, those are some great nuggets of information. I am going to get out the 0 -> 1 micrometer and spend some time in front of the grinder.

It is really good of you guys to share information like this. It is one reason I stay with this forum.

As I read through this fascinating thread I was thinking the same thing.

Just wanted to say,. MANY THANKS, to you gentlemen, today is the second day shaving with this Razor type device, (never seen a real one) and I'm very pleased with the results, I'd say it's better than my electric!
With my new found knowledge I hope to improve on my next build this weekend. Again thanks for taking your time to help.

Nope. I really mean 0.0005". Sometimes I get lazy and go up to 0.002". Using a height gauge, a carbide scribe, and a surface plate, I scribe a center line. When that line starts to look "dirty" (doesn't reflect light well), your are getting just under 0.001", when using a 240 grit belt.

If the bevel width is uneven, either the hollow grinding, or the honing is uneven. It could be either one.

Practice, and a tolerance for tedium...
