Straight Line Air Sander
The Straight Line Air Sander was invented by Otto Hendrickson in 1960. Otto Hendrickson received a U.S. patent in 1965. Karl Selander and Otto Hendrickson designed the first commercial version for ATCOA, Air Tool Corporation of America, which sold the first straight line air sander as the ATCOA Viking and still holds the original patent. The Viking, distinguished by it's sleek die cast aluminum body design and bright red and black color, was introduced to auto body repair industry for the first time by Karl Selander's ATCOA. The straight line air sander increased auto body shop productivity, automating the process of sanding body filler to a smooth finish in less time than hand sanding. The ATCOA Viking became the industry standard straight line air sander. After the patent expired the Viking was copied worldwide to various standards. In late 2009 Karl Selander, the Viking designer, re-released the original ATCOA Viking, based on the original plans and specifications, as the ATCOA Viking II Legend.
