Quoted from Skins:I like to put a nice fresh, clean 45 degree bevel on the cabinet outside bottom edges. It's near impossible to free hand it with an orbital sander. You invariably change the angle of the sander so the outside edge undulates up and down. This is especialy critical when installing/trimming decals. I'm sure there's a tool for this and if so please link me. I always just end up making a 45 degree beveling sanding block out of scrap 2x4's. I present my marvel of ingenuity, lol.
And the result is a beautiful, straight 45 degree bevel.
