Sorry if this has been discussed before but I did a search and didn't find it. My favorite type of turning is the odd shaped, rustic, live edge, sometimes very old wood pieces. Those often have wide cracks or other voids that I may leave or may fill, depending on the location in the piece and if the void adds or detracts from the overall look. I know a common fill is CA glue and coffee grounds and I do employ that. But sometimes a repair with the same wood is better but there are only shavings and no fine dust to use. That's where the shop coffee grinder comes in. A while back I bought a burr grinder and thus retired my old spinning blade grinder but it was only retired from coffee duty. I now use it to reduce shavings into fine grain fill material. Just gather up a handfull of the shavings from the workpiece and a minute or two in the grinder make nice fine fill to use with CA glue. If you don't have an old one, they can be bought pretty cheap.
Some of you probably already have thought of this butmaybe it will come in handy to someone.
