John Lindo,
I have emailed you a manual with a description of the ACCEL trim pot function on the mini-lathe.? Its function is to do exactly what you want to do; to slowly (the adjustment range is 1 - 5 seconds) accelerate the motor based on the setting of this trim pot.? There is also a trim pot to limit the inrush current to the motor.? If you change the ACCEL setting, you must also adjust the speed and inrush current settings.? The manual gives adjustment descriptions.
I would not add additional circuitry here if the function that you want is already built in, and only needs to be set.
I suggest you photograph the original settings so you can always return to them if the adjustments go bad.? Also check the maximum and minimum spindle speeds before making any changes, as you will want to readjust these to the same settings after changing the ACCEL pot.
