What I know about this lock is very little.
It's a Yale
Old
Does not feel like a spring lever
Feels like a direct entry with out false gates
Wheels will bind if I put pressure on the handle turning CCW (Between 92 and 4).
Maybe an OB type?

Many safe makers used the OB, so I'll also say it is possibly the Yale OB.......but

Here is a closer look at the dial.

The Yale HE. Used exclusively on HHM safes.

Thank you!
I will have to look that up in a book to see what's going on. Any tips on manipulating this type of lock?
I am stumped at this time. I looked for it in Oldfast's Safe Chronicles only to find he has been victimized by the Photobandits.
My Boss has some Dave McOmie books at work. So do I graph the contact points like a 6730, or handle rotation like a direct entry?

Chances are it is friction fence lock ... Look at Page 65 (Actual page not PDF page) of The National Locksmith Guide to Manipulation.

Manipulated open.
Over the last month I've been working on getting this safe opened. Ten to fifteen minutes before work whenever possible.
I really didn't time how long it took. I think over all, maybe around 4 hours?. Made 4 graphs. Not being a spring lever type lock, you have to return to the contact area and apply pressure on the handle each time in order to take readings. Your arm becomes the spring. The last round I had was like sitting in front of a Las Vegas Slot machine. With each pull of the handle the excitement built. I knew I was going to hit the jackpot! Spin, spin, spin...Pull. Sorry try again!
Wash, rinse and repeat. Till finally. Spin, spin, spin and pull......Winner!

Great! I am still waiting to open my first real safe.

So the lock was a standard direct entry without false gates? How did you do the reading? Angle of the lever?

I have not opened the lock, but I would say it has three wheels and a drive cam with a standard type drop in notch.
So taking standard readings and graphing were possible. Also, information could be gathered from the amount of travel in the handle itself.

Congrats on your opening, jharvee!

I found a link to a photo of what is in the door.

Fantastic! I've not had the pleasure of running into one of these yet. Can you tell us more?

a. What fed you more info? Right or Left CP?

b. How wide were the gates when they indicated?

c. How much fluctuation did you receive for a gate sig?

d. Do you feel it would be worthwhile/necessary to set up
a rig that would apply more consistent handle pressure?

Great job... and thanks for sharing! You're gettin' good.

Hi Oldfast,
A. Right side seemed to show more movement.
B. 1, very narrow.
C. Wheel 3 had a huge drop on graph 1. Nearly 7/10th. Wheel 2 almost nothing 1/10th. Wheels 1 and 3 were egg shaped and shadowed wheel two.
D. consistent amount of pressure would help. I had even thought turning the safe upside down would help, but was not an option.

Well damn, you gotta be on your game to catch gates like that. Nice job.

And again, thanks for sharing your experience. Very helpful info for the future.

Is this sort of thing common? I suppose it's an easy way to make manipulation harder. Congrats on the open!
