Re: [ATM] question about tiles on a beveled glass tool

[Dale Eason <atmpob@yahoo.com>]

Why do you want to put tiles on a tool that will
already do the job without them?  Tiles are generaly
used when you make a tool from scratch out of material
that is too soft to grind against.  Then you add tiles
to it that have a harder surface.
