It is embarrassing but they are so useful.
last night I chopped a half inch piece of seasoned hazel off a stick, screwed a wood screw in to it, use the dremel to cut the screw head off so that the little handmade tool could then be mounted in to the dremel. I then turned the dremel on and used a piece of sandpaper to cut a grove in the circumference of the hazel as it spun round and now have an automated leather edge burnisher.
Miss Cottis is very happy with her new glasses case and I was very happy with the slicked burnished edge of the leather. Mmmm, cognac horween leather and naked assembly (I was wearing shorts really)
