Terry, I'm sure you'll get lots of different answers to this one! For me it varies from "I don't sand" to "on the belt sander". For feathering and celtic cross stuff where you don't actually cut the blank apart there is not much you can do to get into the kerf and sand - maybe fold a piece of sandpaper double and slide it up and down in the cut to get rid of the worst of the rough stuff. For more complex segementing where the angle of the cut is critical (like my AdAstra) you can't be too free with sanding or you will alter the angle and ruin the join, so I use diamond warding files to carefully clean up the surfaces. Where it is long straight pieces I just run them over the belt sander (with a very worn old belt on) to flatten them. I use gap-filling glue too (thick CA or two-part epoxy) so that any gaps will be filled.
