Despite our best efforts at maximizing space, we simply can't find room for a drum sander in our garage, even one slightly smaller than this one. It's the one tool for which I still use the community woodshop, and hope that no one has just tried to sand off paint, or used resinous wood and ruined the sandpaper. I use the drum sander primarily to level glued up blanks made from various types of colorful wood--it's the best way I've found so far to get a smooth blank that is evenly thick.
However, I have discovered that even though the blank appears flat, it usually needs further work, and that's where I use the SandFlee. The flatter the blank, especially for bowls, the easier it is to glue up the rings without spaces. I also use the SandFlee as a jointer to get my strips ready to glue up. Next step is to get a flex shaft extension for the SandFlee so I can sand places that I can't reach using the drill press. And that will be my Mother's Day present. Not as pretty as flowers, but a lot more useful.
