Sutherland also had a nifty little record weight/strobe timer, the $900 Timeline. Yikes!
It's an awfully clever little dingus. The body is made of machined Delrin and machined aluminum. Set into the aluminum part is a laser pointer programmed to blink exactly 33.3 times per minute. Slip it onto your spindle, wait for the table to get up to speed and then you play "find the dot." The laser will project onto a surrounding wall and you simply observe whether it hits the same spot every time (spot on) or if it wanders.
Sutherland calls it the "last word in precision," since the laser's accuracy is 2ppm.
