My Tree Mill Journeyman 300 came with a low pressure air cylinder and a
regulator with solenoid valves for shifting gears. I decided I would retain
this set up when I retrofitted it to newer servo and spindle motor controls.
It works great. Use 120VAC solenoids and 30 psi air pressure to actuate it.
Seems to shift right into gear without the spindle turning.
