S&G
I am currently working on my first combination lock and it is an S&G 3 wheel 6730 combination lock. I have read the manipulation for computer science many times as well as various online resourses and forums.
I am having trouble with getting the first number. I know the article for computer science talks about a combo lock manufacture defect where the spindle connecting the cam to the dial is not straight and i believe this is what i have. You can see the dial doesn't spin exactly straight. Also while trying to map the whole wheel pack together to get the first number i notice that my contact area stays exactly the same (down to 1/8 incrememts - having trouble reading anything smaller then 1/8 with accuracy). Then as i get half way around the dial the contact area gets tighter for a while, then back to where it was.
My graphs do not look like hills and valleys, more like straight linee with a deviation every now and then.
I do feel like the contact area gets narrower on each contact by 1/8th increment from 50-52, but it is flat and goes back to regular contact area after this. I don't know if this is whata gate signature would look like.
Any help or advice would be appreciated.
