Thorens used to make a portable, stick-on auto arm lift device for 10-20 dollars or so.
I put on on my manual table back in the 80's and it continues to operate without error to this day (look at the pic of the Linn Axis table in my system and you can see it mounted between platter and tonearm mount on my table near the rear of the arm).
Not sure if such a device is still available these days, but if so, properly adjusted and located, it is a reliable add on for a manual table to automatically lift the arm at the end of play.
