In a woodshop with limited space, having one tool perform multiple functions is invaluable. Instead of investing money and shop space in a drum sander, I glued two two-by-fours together and turned them down to make a 3"-dia. dowel. I then wrapped adhesive-backed sandpaper around the dowel. Remember which direction your lathe will be spinning when you attach the sandpaper so it doesn’t peel itself off while you’re sanding. Once the lathe is turned on, you've got a drum sander.
