I've read a few of the threads about American 700's and still and having a problem with this lock..
this is what I "think" I've been able to determine so far
1) the 1st and 2nd pin are serrated (based on visual confirmation).
2) I've never been able to get ANY binding on the 1st and 2nd pin.
3) The 2nd and 3rd are spool (serrated spool I suspect, as I can get 2-3 "clicks" on them)
4) Important.. with an SPP, Ive never really been able to get a good "set" either False or regular. the core just does not seem to give a good "rotation" with them. I can feel them click, and feel binding but that's it.
5) 5th pin is similar to 1,2 and I can't feel any binding
I have been able to get 2-3 pins to feel "set" (eg they click when I release tension) if I rake the lock with a w lock, but again I don't feel the plug rotate.
I don't have the key to this lock, so unfortunately I don't know if it even works (but the plug does has free rotation of the smallest amount with no "gummy" or binding feeling (so I suspect the plug will rotate ok..)
I've also tried light, and heavy tension (but still no rotation on a set, or false set..)
any advice from the masters?
