The idea is not to pick it open but to make a key. Once you've rotated half way between two pins, you can remove the tool and measure the heights of the pins.
I like the idea of having a limiter sleeve on the outside to ride in the
slot.

How about making it with two concentric tubes; one operating, and an outer
partial one that locks to the outer notch, with a slider between the
tubes, so that you are applying tension to the inner tube, but the outer
one limits you to not making it as far as the next pin position.

But, for use as an unlocking tool, you do need to turn more than one pin
position, often as much as 90 degrees.  So, though it would pick the lock,
you WOULD need to repeat.


Please let us know how it goes!


I'm a bit overdue on machining a better version of the conventional one -
calibrated pin positions, better adjustment of resistance including
solid locking of them, including being able to work with and without
detents at the standard cut depths.


Lack of necessity is the mother of procrastination!
