Thread: Razor Making Fail

I don't usually pay much attention to the math of selecting wheel diameter. Sometimes I just use what I got, which by the conventional wisdom is usually way too small. Like @bluesman7 said, the grind does not necessarily precisely reflect the wheel diameter. In a perfect world I would have two professional grade 72" x whatever grinders in twin configuration with lots and lots of contact wheels. The reality is a bit different and I have clamped my share of belt sanders upside down in the bench vise. A twin grinder is on my list of projects to do. Unfortunately it is a long list. When you are retired, you never get a day off.

Makes sense

It was a fun project even though it ended in failure

Single grinder is enough for me

The perfect world? Do I note a bit of "ting-ting" at 1:00-1:02?

Love the little twin grinding wheels! Cute! I think I know what I want for Christmas next year!

Doc-I'm sure you are familiar with the story of how many different filaments Edison tried that ended in "failure" before he found the magic for his light bulb in tungsten (over 100 as I recall). As I don't grind or hammer steel, I admire guys who do, and have no doubt that you will nail it soon. I for one look forward to your 1st finished custom razor. Judging by your past work, I know it will be a beauty!

Wheel diameter has little to do with the hollow diameter because you typically don't grind with the entire hollow in contact.

Also about heating to cherry red: don't focus too much on the color itself. When you are heating, it will turn reddisd orange. At some point you'll see the brightness make a jump and it will be much brighter. That is when you know you are austenizing properly.

Looks like a 6/8” wedge is in the future for that blade, just saying, or it’s just on the learning pile
