Thread: Razor Making Fail

I've had a belt sander for some time, used if for restorations, decided to try to make a blade

01 tool, I made a rough cut out


Spine


Grind after 40 grit


Not too bad

Jimps

Got it to here

Heat treat in very crude set up, got the metal glowing to a cherry red and quenched in warm oil



Tempered in oven and started regrinding
Got it descent then this happened

It was going well, I was checking the grind by honing on a DMT coarse plate, almost had it and just went too far.

I was using an 8" wheel, I think I need to try on a 10", the metal got thin

Overall great experience and will definitely try again

I think the heat treat was good, I tested after and a file glided over, I was also getting nice sparks with with the grinding

I did the post heat treat grind on a 320 belt

What happened? The last pic didn't show up Alfred. It had a great shape.

Oh that's a very thin grind!

Might be easier on the fit and finish at the end if you go with a higher grit when you start getting close to the grind you want.

Shame that happened after such a good start. I bet you get it next time around though.

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
