Threaded bible and core

[Shackle Jackal]

I was searching and could not find anything about threaded cores etc, does anyone have any advice on how to pick threaded cores and bibles ? how to make them? or maybe an FAQ or something similar ? any help would be appreciated

Just want to clarify. You said picking a threaded core. Did you mean a threaded pin chamber in the plug/core, as well as threaded top pin chambers in the bible? Or were you referring to something else done to the core to make it more difficult to pick?

Do you mean the custom ones that people make and send to each other on youtube as challenge locks, ie. Bosnian Bill and others?

You didn't find anything because that's a relatively new thing compared to how long this forum has been around, and actual locks you buy from the store these days don't have threaded pin chambers. I think I have a very old Yale from the 1920's that did some threading in the chambers.

If you seek advice on how to make them, I would ask the people making the videos to post a video on how they tap the chambers.

PS. and ltdbjd is right, there's no such thing as a threaded bible or threaded core, only the pin chambers in the plug or in the bible are threaded.

Curiosity got the better of me, and I did this to a few locks a while back. Used a 4-40 tap for full size and a 2-56 for padlock if I recall. Could have been the next size up in each respective case.

Even when paired with serrated pins, I personally found the threading made it easier to pick. Don't know if it's just a configuration that suits my picking style better, or if the threading destroyed the close tolerances the locks had in their natural state.

I can post pics if you but I'm quite confident some of the plug pin chambers in American cores have light threading in one or two of the chambers, not sure it has any effect though. I think it was on all 5 or 6 of my cores, but it has been a while since I opened them all up(my cores are a mix of from Gordon, Mr. Lock, and the local locksmith).

Amazing! I would love to see some pics.

It really is true what they say, whatever is old shall be new again.

Yes I suppose I did mean the chambers and or core - thanks for the correction- I am not exactly sure of what to ask or how to say it, I always seem to have trouble getting the words out of my head and onto the page. I was just looking for some feedback as to what other people have experienced. Seems like I will just have to thread some cores and chambers and give it a shot... thanks all

I did it again, *thread some chambers both bible and core*

Still wondering where you got the idea that these types of cylinders are a common thing, pretty sure 99% of us havent picked one that had threaded pin chambers. Not unless someone else in locksport custom made one and mailed it to us as a challenge lock.

Im also not really following anyone on youtube so there may be trends going around that Im not familiar with.

Thanks,

Did I give the impression that I thought they were common ? I realize that this is more common in challenge locks and you will probably never come across this in someones door, a padlock etc, and yes I have noticed a fair amount of challenge lock videos on youtube with threaded chambers.

recently I met up with a fellow picker and he has been making me challenge locks, he is going to start threading the chambers top and bottom, thus the questions.

Hi, I've threaded a few cores and found that combined with the right serrated pin (from Sparrows reload kit) it can be effective. I would use light tension and pick like an American lock. If you want to learn, use about 3-4 locks and thread one chamber on the first, two on the second, etc. Have everything else the same and go! This should allow you to build a feel for it. Once you have that, feel free to thread in different combinations and good lock! If you don't know how to feel for them then they'll cease the core (if the threads are deep enough). I used an allen screw that came from another lock so unsure on the size. If you thread the chamber and the core it makes it trickier and provides a good challenge.

I'm learning new things all the time and so my info is based on personal experience. (Don't use a screw the first time, especially if the threads match)

Funny I was just watching Bosnian Bill pick a couple of your challenge locks (very nice BTW). I should have figured progressive "threading", looks like I need to start hitting up the habitatRESTORE again for some cheap locks ! Thanks !

Hi,
It just seemed you were surprised there wasnt a bunch of threads on this topic already which made me wonder if I had missed out on some hot new thing everyone was into.

I did some digging and here is a thread from 2010 talking about it: viewtopic.php?f=25&t=47420

It seems some folks feel it makes it much harder to pick and some feel it makes it easier. If the pins are ringed or serrated, I would lean towards it being more difficult to pick. I recently bought a tap and die set, perhaps some hands on is in good order!

So I went through my 5 plugs and only found one.



Not sure why I thought otherwise. My bad.

The threading in locks is almost impossible to see unless you're looking for it. I went through mine and found 2, both American locks. And one with only a single groove, it's my twin Assa.
