Herb Tautz started Delta Manufacturing in his Milwaukee garage in 1919, and its first hit was a small scroll saw. By the late 1930s Delta had the Unisaw, the 14 in band saw and a full line of home-shop machines, and in 1945 it became the Delta Power Tool Division of Rockwell Manufacturing of Pittsburgh. That's why so many old machines say Delta Rockwell. The Milwaukee plant closed in 1952, and production moved to Bellefontaine, Ohio, and Tupelo, Mississippi, so a Milwaukee address on the plate means 1952 or earlier and Pittsburgh means 1953 or later. Rockwell became Rockwell International in 1973 and sold the machinery business to Pentair on April 12, 1984. Black and Decker bought it in 2004, and since 2011 the Delta name has belonged to Chang Type of Taiwan. Delta's serial tables are well kept, so most Delta machines can be dated to the year.
