Well, I'm at it again. Adding more function to my Shopsmith. There are times when a thickness sander is a better choice than a planer. I plan to start building acoustic guitars at some point and there's a real need for gentle dimensioning that a planer just can't do. If you followed my recent swing arm sander build, you may have seen my plan for a drum sander add-on to the belt sander. It would be too narrow to do the work needed for acoustics. So, I've been thinking about a stand alone sander that would be powered by the Shopsmith. This is what I've roughed out. Still lots of details to work out but it should be much easier than the belt sander. It will rest on the way tubes and be powered using the Shopsmith quick connect coupler. Four gears on a chain drive will adjust the height of the table. At the moment, the design is manual feed but I want look at adding a power feed...one of the details I still need to figure out. It might be a few weeks before I start the build but I'm collecting parts and pieces and continuing the design process.
