Wilson Bohannan padlocks

The infamous Wilson Bohannans. These locks intrigue me. WB's are rather interesting when you consider
the fact that they contain no security pins, and yet, offer a surprising degree of resistance to picking. The
company is known for their precision machining which yields the high tolerances found within their locks.

A quick & interesting 3 min vid takes you from the start of the company in 1860, to the modern day, 150+ year old company:

From picking these, I deduced, and certainly agreed with everyone that said "nothin' but standard pins & high tolerances". However, after picking a wide variety of these, I was equally certain that there had to be something.. SOMETHING more to these locks... lol.
I suspected some beveling... if not on the pins, then maybe the chambers in either the housing and/or plug were flared.

So, as I pulled one of these apart, you can imagine my dismay. I was like a child who opened his Christmas gift, only
to find a lump of coal. Apart from the very, VERY slight bevels on the pins... everything seemed fairly standard



A couple days later, still feeling a bit cheated, I decided to sacrifice one more lock. I carefully chose one that had given me a hard time (hence, one of my favorites). And..... BINGO! A satisfying grin as I revealed each pin. The contact end of the drivers were rounded. And the top of each keypin had an EXTREME bevel.



The interaction between the pins, coupled with exacting tolerances is a recipe that's sure to leave you with that annoying aftertaste of overlifted pins. This also accounts for why my method of dropping keypins frequently while picking proved so affective with these locks. It's also possible to have the rounded drivers sitting too low. A light nudge on each pin, or a gentle rake will often cure this.



One other piece that was abscent in the first lock I gutted. This 'barrier' pin is inserted into an additional chamber in order to seal off the back end of the plug. This prevents direct access to, and manipulation of, the latching mechanism.

Ahhh, I can now sleep sound tonight. lol

Hey Oldfast, great pictures and info. I also appreciated the WB history video.

On a side note, I think that these pins should make the lock extremely easy to pick! I've never played with it so I could be wrong, but a tapered keypin should push the top pin past the shearline and fall down straight away, without the risk of getting caught by the plug hole border. And the bevel of the top pins should help to create a HUGE shearline: from the top of the top pin bevel to the bottom of the bottom pin taper.

Cheers

Mr. Oldfast...

Dare I say that you and your posts are the single greatest addition to Keypicking since the chat board.. You have greatly enhanced the content and information that this site has to offer and on that note I want to personally thank you for the time and effort you have put into your posts and the information you provide us all with. You are most welcome here and I for one hope to see more of your stunning photography and information posted as you too explore the world of locks.


THANK YOU,
Whizdumb

excellent post oldfast...I might be lucky enough to get one of these shortly and was wondering how the plug comes out...i'e' is there a screw under the shackle?

[xeo]

oh my god. what did you do to that beautiful wilson bohannon! i love these locks.

Thank you femurat. And your assumptions are more or less correct.
The only thing that you didn't take into account is that WB's are fuckin' freaks! lol

In fact, the use of beveled and/or rounded pins are usually geared more towards functionality rather than security. They help the lock operate more smoothly and reduce the amount of wear. For example, the bitting on a key may wear down over time and will not lift the pins quite as high as it use to. But the key will still operate the lock properly since these types of pins create for a much more forgiving shearline... just like you mentioned.

On the other hand, manufacturers will sometimes use these pins with security in mind. But when that's the intension, they're normally coupled with flared chambers on the plug and/or housing. Yet, these locks have no flared chambers... so again, just freaks! lol
Also, this is the most extreme beveling I've seen. Usually, they're not nearly this drastic.

Hopefully someone will jump in & explain this a bit better... but here's my experience with these; When you set a pin, it's quite apt to be overset (a small portion of the keypins' beveled tip sets just above the shearline and jams there). But you'll experience a slight amount of give in the plug, giving you the impression that the pin has been properly set. And the fact that another pin is now binding only helps reinforce this thought.

So it seems there are two ways in which you can attack these locks. One, using light-med. tension, along with delicate precision with the pick, being cautious not to overlift anything. Or, (as I've come to do) a staight up, full hard-on attack... lol.. more of a 'rough & tumble' kind of style. Hard tension, hard pickin'. I'm bound to overset pins in this manner, so I frequently ease off tension in order to drop overset keypins. There's also the possibility of a driver making its' way back into the plug. For this, a gentle nudging kind of lift.... or a light 'brush over/raking' from back to front will help work them back up out of the plug.

One things for sure... however you decide to tackle these, they're fun picks! I've a couple that seem to pick like nothing more than a laminated master. While others really give me a good run for my money.

excellent post oldfast...I might be lucky enough to get one of these shortly and was wondering how the plug comes out...i'e' is there a screw under the shackle?

Thanks. These locks are self-contained and are not designed to be disassembled. All the pinstacks (as well as the retaining pin) are dropped into their chambers, capped, and sealed within the body. You're only options involve grinding or drilling. But look on the bright side friend... I just slaughtered two of mine, so you don't have to kill yours! lol

oh my god. what did you do to that beautiful wilson bohannon! i love these locks.

Holy shit Whiz... what an awesome compliment! Your kind words are deeply felt and very appreciated. I love this hobby, this forum, and everyone on it. I get immense enjoyment from it all, and it certainly keeps me busy. And for someone like me, with my past.... busy is ALWAYS a good thing! lol

RR BRINKS MOGUL CYLINDER

Application: Prisons & Jails

The Mogul cylinder itself, along with its' operating and control keys.

The lock utilizes a master ring which creates two shearlines. One between the ring and the plug, the other, between the ring and the housing.

Contained in each of its' six chambers is a ball-bearing, keypin, masterpin, and a graduated spool.

Some XXX, 3-on-1 lockporn for your viewing pleasure. That poor, helpless Schlage never stood a chance.

how does one get a mogul like that to play with? i have the manuals for service and repair, but no locks to play around with.

Thank YOU. I'm glad they can be shared & enjoyed.

Two of them I purchased on ebay (you'll see them from time to time). Try searching 'prison lock' maybe.
The other Brinks is on tour thanks to the great Kokomolock! It's headed for England next.

awesome stuff! /me wants!
