THAT would be an ideal pinning for it!
Anybody remember/save the actual pinning depths from that discussion?
(XX2247 is a "code number" that indexes into an array of actual
dimensions; XX2247 is NOT the depths of the cuts)
See below:

Here's what I got from two original XX2247 keys...
The cut depths, clockwise from the first position, looking into the open
end with the key at the "twelve 0'clock" position are:
Key 1 Key 1 Key 2 Key 2
0.0770" 1.94mm 0.0785" 1.95mm
0.0150" 0.37mm 0.0155" 0.39mm
0.1055" 2.68mm 0.1070" 2.72mm
0.0435" 1.13mm 0.0455" 1.13mm
0.1075" 2.72mm 0.1085" 2.74mm
0.0780" 1.96mm 0.0785" 1.98mm
0.1075" 2.72mm 0.1095" 2.77mm

I'm not quite sure what this says about
cutting tolerances or what multiple
the depths of cut are.
Not sure about tolerances (my brother is a locksmith but I'm not), but
according to...
http://www.locksafesystems.com/depth_and_space.htm#Chicago_Tubular_Space_an…
The depths by number are:
1 - 0.0155"
2 - 0.0310"
3 - 0.0465"
4 - 0.0620"
5 - 0.0775"
6 - 0.093"
7 - 0.1085"
8 - 0.1240"
Meaning that the XX2247 key would have depths (in the order you
describe) of 5-1-7-3-7-5-7
A locksmith set up for ACE cutting would have the code book to convert
the serial number into the depth sequence, so the number on the key is
the important datum. Knowing the numeric depths is handy when you are
pinning a lock so you know which bin to pull pins from.
