When using drill bit shanks as plug followers, you sometimes need to use a
piece of shim stock to keep the pins from falling in the gap between the
plug and follower.

My comment was that it's not much fun to have
somebody else do the work.
Not that locksmithing isn't fun (it is...)
Some people just don't appreciate fun. (or have too low a frustration
tolerance level to handle locksmithing (or assembly language programming))
Well... my

pin-tumbler lock *pick* - it is essentially a follower that is the same

It is possible to pick a cylindrical lock like any other -- by applying
torque and picking the pins one at a time. The problem is that once
you've done this, the moving disk (see my other posting) will move
through the angle between the pins (perhaps 1/8 revolution) and then lock
again. And you'll have to pick it again. Considering that you might have
to turn the disk through 3/4 revolution or something, this is a somewhat
impractical way of picking the lock.
The commercial tubular lock picks have enough friction that once a pin is
set, the pick stays in position and that pin does NOT relock when you get
to the next position. And the tool can even be used as if it were an
original key in duplicating a new key. That ability to work with all pins
at once is one of the big differences in working with tubular locks. You
could make such a tool with a piece of tubing, or a key that has the
correct pin positions (kinda like picking the correct DIN connector).
Mill slots and put in sliders. Give the slider enough resistance that it
will push pins, but won't force a set pin out of position.
Note that a lot of cheap clones have what looks like a lock, but will open
with damn near anything that will fit in the keyhole.
