I used a paperclip to hold the threaded cap in place. You can also see where I dremeled in some notches for the impression resistant pins on the side (barely).
This is the pin grabs the tailpiece if the sixth pin is held up.
And a picture of all the inside components. To pick this lock you need to make sure that all of the master pins are above the sheer line. If they aren't, then the driver pin acts as a trap pin. This doesn't completely lock you out though, since you are always able to turn it back to the neutral position.
Mainly I just wanted to show off the clutching mechanism. Which unfortunately will probably wear out pretty fast under heavy use. Stronger material would be very important if this were to actually be installed somewhere.
