Building The Towersander

Building The Towersander Having built the oscillating drumsander I wanted to try building something that could do a similar job without the hazzle of changing drums to do different diameter curves. I figured it had to be compact, easy to use and I wanted it to run off an old powerdrill. I started by cutting out the  circles for the drums on my circle cutting jig, on the bandsaw. They are cut form 18mm BB plywood tower sander.Movie_Snapshot   All the discs are glued and stacked on a 12mm threaded rodtower sander (2).Movie_Snapshot tower sander (3).Movie_Snapshot Clamping is applied just by tightening the nutstower sander (4).Movie_Snapshot Parts for the back and the shelves are cut on the tablesawtower sander (5).Movie_Snapshot All the shelves get 2 extra layers of 18mm BB plywood for support at the hingepointtower sander (6).Movie_Snapshot  And the excess is cut off at the bandsaw.tower sander (7).Movie_Snapshot Support brackets on the oposite side of the hinge are glued and nailed in place.

I made a lot of vent holes to make sure that the powerdrill did not overheat.tower sander (16).Movie_Snapshot Installing the bottom shelf of the sander after the parts are painted.tower sander (17).Movie_Snapshot Assembly of the mount for the powerdrill.tower sander (18).Movie_Snapshot The tower is installed. the lower bearing is press fitted into the lower shelf.tower sander (19).Movie_Snapshot Top support gets screwed in place.tower sander (21).Movie_Snapshot Powrdrill goes into its collar holder and chuck tighten over the pertruding lower part of the stacked drums.tower sander (22).Movie_Snapshot Starting to allign all the 4 shelves for isertion of the pipe/hinge.tower sander (23).Movie_Snapshot Inserting the hinge pipe.tower sander (24).Movie_Snapshot Securing the powercables and wiring the powerswitch.tower sander (25).Movie_Snapshottower sander (26).Movie_Snapshot Shelves swing out to give access to different siz drums.tower sander (28).Movie_Snapshottower sander (29).Movie_Snapshot Or all of them can be removed for freehand sanding on all of the different diameter drums.tower sander (30).Movie_Snapshottower sander (31).Movie_Snapshot I am very happy with how this sander turned out. I had been grinding the idea in my head for a long long time before coming up with this design. There are no dustcollection designed for it yet, but that might be an addon that I can cover later on. If you are interested in building this sander for yourself, there are plans available in my planstore.
