manipulation #19Diebold 177-39Group2 ... 3 wheel ... key change ... spring loaded fenceA beautiful lock. Just
beautiful. Everything cleaned up quite nicely with this one.
The dial action is incredibly smooth. And the wheels - hell, I can barely feel 'em pick up.
(Just for the record - I believe the spline key should be seated with the flag over the spindle, not the cam)A rather interesting type of relocker in this old Diebold.
The piece is installed prior to placing the wheels on the post.
The cover plate presses the prongs down flush allowing the bolt to move freely.
Without the pressure of the cover plate, the prongs rise up into the
track enough to catch a ledge on the bolt so it cannot be retracted.

UNKNOWN COMBOL37 - R55 - L33BINDING ORDER1 - 3 - 2Just as with the
0900, it is the LEFT contact point that will offer us the most fluctuation --
NOT the right contact point we've grown accustom to with S&G's, LaGards, and many others.
The choice of starting with a
left rotation is just a preference. If I were taking readings on only
the
right contact point (like on an S&G) I'd start with a right rotation. Again, it's just a preference.
I like to approach the CP in one fluent motion, rather than having to change directions once more.
Most gates are normally 2-4 incs wide. So a one-increment peak struck me as a
little odd.... but no doubt a gate.
I'm assuming that one or more wheels were masking this gate. So I guess I'm just lucky to have caught what I did.
Much of this manipulation consisted of me attempting to tag 36 to a wheel! lol

Not only does it indicate multiple wheels, but

Performing the same test, with all left rotation (
mentioned in previous manipulation)
indicated wheel 3. But again, only 1/10 of a drop. Neither of these tests were
conclusive enough for me. Just felt like I'd be rolling with an assumption.
I've not documented everything here, but I will say... after attempting a couple more hi/lows using different test #'s
as well as isolation... I still had nothing concrete to go on. With 36 being on an undetermined wheel, I was a little
at odds as to where to go from here. I briefly considered just assuming it was w3 (and the odds are in my favor),
but the idea of running 1&2 on more or less a hope with good percentages just didn't appeal to me at the time.
The more sensible option here seemed to be: run w3 while leaving 1&2 on the good indication of 36.
1) I'll find a gate for w3, or 2) I'll find nothing, but will have ruled it out & taken less overall time to do.
CPT1911 has talked in detail about this option and found good success with it. Until now, I've never
had to use it. But finding myself in this little dilemma presented the perfect opportunity to give it a try.
I parked wheels 1&2 @ LEFT 36, and started w3 around RIGHT. Initially, I was taking readings
every 2 increments (34, 32, 30, etc.). But when I hit the extreme drop at 30, I started again -
this time taking a reading at EVERY inc. A nice 3-inc wide gate spanning from 32-35.
- - R33.5Also, the good indication I initially found at 36 with an AWL rotation?.... (
I wasn't certain of this at the
time), but I had a feeling that this was an
entirely separate gate from the one I had just found for w3.
Remember, testing for 36 had left me at odds between wheels 1 OR 3. Having now found w3's gate,
I'm wondering if 36 belongs to w1. I try to confirm this through isolation. It is indeed wheel 1 AND the
fence has dropped onto w1 enough to catch the
entire gate this time rather than just the edge at 36.
L37.5 - - R33.5Before brute forcing w2, I wanted to convert w3 to a LEFT rotation.
Recall at the beginning I was unable to determine pick-up differences.
So I simply run w3 through the area, but with a LEFT rotation this time.
Park all wheels at LEFT 37.5. Go around RIGHT to pick up w3...
bring it to about 20. Go around LEFT to pick it up again at 20...
bring it to 30 and start your readings (30, 31, 32, 33, 34, etc).
Upon doing this I found the gate signature to be nearly identical.
So I now know I can safely approach 33.5 from
either direction.
L37.5 - - L33.5Wheel 1 is the 'rotisserie' of the wheel pack... you can "
set it and forget it". I place it at LEFT 37.5
I can now work wheels 2&3. I move w2 around RIGHT in incs of 2 starting at 30, (28, 26, etc.)
EACH TIME I move wheel 2 I must REPOSITION w3 at its' known gate of LEFT 33.5
With some oscillation, the lock actually first opened at 58.
But at 56 the fence drops in smoothly with no coaxing.
OPEN: L37.5 - R56 - L33.5
