SnailForge Posted May 31, 2016 Share Posted May 31, 2016 Last February I was in Texas in a gathering of razor makers. It was a place for people to get some insight in various aspects of razor making, and I was helping people make their first razor, explaining things and doing a couple of forging demos along with Howard Clark and Mike Blue. One of the things that came up was: how do I grind a razor the last bit of the way after heat treatment. There are many ways to do this, and I won't say that my way is best. This is just what I do and it works for me. One benefit it has over other methods is that I get very small bevels on my razors which can be a bit harder with other methods. I was the only one of the people there who ground edge down, and one of the science-y guys wanted to film this to make a tutorial and this is the result. One of the benefits this has is that the sparking and even more important the sound of grinding tells me just where I am in relation to the edge. It takes some practice to get good at this, but by looking at the sparks and listening to the sound I know exactly what is happening to the part of the blade I can't see.

BIGGUNDOCTOR Posted June 1, 2016 Share Posted June 1, 2016 What grit belt, and surface feet a minute are you using? Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted June 1, 2016 Share Posted June 1, 2016 Thanks for sharing this! I got a good feel for this, just by watching you! I have my grinder set to rotate the opposite direction. I do like to watch for the foil when I'm grinding edges! Quote Link to comment Share on other sites More sharing options...
SnailForge Posted June 2, 2016 Author Share Posted June 2, 2016 The belt in that video was 220 grit. Personally I like to use 120 grit ceramic after HT but at the time I had the choice between 60 or 220. 220 worked but was a bit slow. SFM I don't know It wasn't my machine and it had no numeric setting just a turn dial. Fairly slow.I run my belt at only 10 % of full speed at that stage during hollow grinding and I'd say 2 bumps per second on a 72 " belt.

BIGGUNDOCTOR Posted June 2, 2016 Share Posted June 2, 2016 72"x2per second=12' per second x 60 seconds in a minute is 720' per minute. Quote Link to comment Share on other sites More sharing options...
