Aloha, Here is the exotic and interesting Louis Allis Control panel, motor and frequency changer needed for an Oliver direct drive shaper. It is the only one I have ever seen. Inside the panel is immaculate, a real time capsule. Came with the original 1956 blue line drawing of electrical layout. It came with the Oliver 287 shaper; see that photo index for the story. Very Cool!

Hess Custom Woodwork Inc. Research on Frequency changers;

American Wood Working Machines for pattern shops 1920 American #30-A & 20-A Double Spindle Shapers on page 53. "7200 R.P.M is the speed recommended for the spindles, and at this speed the motors develop 4 H.P. each. I order to obtain this speed, a frequency changer is required which generates 120 cycle. When a number of shapers are located near each other, one frequency changer serves them all."
