Here's a video showing the Shopsmith Strip Sander being used for sharpening Plane Irons
Here are a couple pics from the 1988 or '89 annual Manager's Meeting when the Strip Sander at the new aluminum bandsaw table were introduced. The gentleman in the green and white striped shirt conducting the demo is Tim Silvers, the product manager for the sander. The meeting was conducted that year at the Carolina Hotel in historic Pinehurst, NC. I think I tell the story elsewhere on this blog about what happened during this demo when they demonstrated the bandsaw table... that's a funny story.
