S&G6730: Some combinations won't reveal a gate?
I'm a newbie to this safe lock manipulation stuff, so please forgive my ignorance of the subject. Both my son and I are interested in lock picking and now manipulation. I recently purchased a Big Red Wheel CDL-3 cutaway on a practice stand from MBA USA as well as their S&G 6730 combo pack and a practice stand that I mounted it on myself. I also have a copy of National Locksmith's Guide to Manipulation, which I've read a couple of times, and watched safe manipulation tutorials on YouTube.
Here's my question:
Both my son and I would set a combination on a lock for the other to manipulate open. However, I (accidentally) came up with a combination that is unyielding to revealing any gates on either the S&G6730 or the CDL-3. That combination is 28-74-41. I have graphed out that combination with AWL, AWR, and parked W1 & W2 to try to find the gate on W3 on BOTH of those locks. I get no discernible information that I can see would lead me to infer a gate anywhere. Has anyone else ever experienced this? Is this a thing that can happen? Or is it that I'm WAY too much of a novice?
What I observe on the CDL-3 cutaway, is that the inner-clamp (?) on W2 comes up to the surface of the wheel and possibly a few thousandths of an inch above, thus lifting the level. This is just about at the same point of the gate on W1, which then becomes shadowed. I don't know if my conclusion is true; it's just a hypothesis.
Thanks for your help!
