light bulb test

[mackie]

Some of the older guys here, will probably laugh at this but I found a way to designate where some of my hones fit into the series of honing. I buy them from flea markets and antique shops and sometimes I have no idea exactly what grit they are or where they fit in. A light bulb blew out over my bench today and I got the idea of rubbing it on a couple of the stones to see if I could tell what grit they were. I still do not know exactly but you can tell which one is the smoothest by the feel and scraping sound or lack of it. I know it is a really crude test but it helps. Works for me !
