Neat key, pin tumbler + tubular

by **linty** » 5 Jun 2007 17:47

oops.......

Apparently this used to be used in canadian mailbox locks. Made by National, I have a lock too but it's kind of mounted on a board unfortunately, but it's nothing special to look at really, the key says it all.

If any mod sees this can you delete my first post?

That is pretty neat. I'll have to look around and see if there's still a lock like that made, although I imagine someone would have mentioned it by now if it was.

Thanks for sharing that.

why not have the tubular part of the pick extend the furthest into the lock, and have the bitting of a regular key on the top of the key tube. I think that'd make it harder to pick.

like this

Code: Select all: ____ / \_/\/\/\/\/\/\/\__ | -----------------/ |o \ | _______________/ \_____/

hope that shows my thoughts well enough. wouldnt that make it harder to pick since all of the parts of the tubular lock assebly would be further back?

I guess I just suck at those drawings....

it looked good when I typed it up..

To use ascii art you must enclose it with the code tags. Be sure to preview as it always seems a bit skewed even with code tags from what it looks like during the initial post page.

I edited it to what I "think" you were trying to draw. If I am wrong let me know and I'll get rid of it and you can repost again.

Neat idea by the way :wink:

That's a really clever idea. Given the way tubular locks are designed I'm having trouble picturing the inner workings of this hypothetical lock, though. Specifically how each mechanism would interact with one another...

Well it is late here so I'll explain the best I can. Hope it makes sense.

The plug of the lock would be larger in diameter than a standard tubular lock plug. Then it would be sleeved up to the front of the lock. The sleeve would be machined into the plug of the std tubular lock to form a solid piece. Then the "sleeve" could house the std key pins while the back end housed the tubular pins. The shell of the lock would house the std key security pins etc while the back of it would house the standard tubular pins.

Hope that made some sense :lol:

having the tubular jobber at the end of the key would also do a nice job of visually masking the proper bitting of the key.

anyone besides me realize that having the tubular part at the end of the key would mean the keyway would have to be wide enough to accomidate a tubular key?

it would make picking the pintumbler part pretty easy.... with a pencil

UWSDWF, that just occurred to me mid-way through reading zeke's post, ha ha. Funny when you get excited about a new idea and the most painfully obvious problems just escape you...

Actually it could be similar to the maxis lock. I have posted pictures so take a look. it has a circular wide open keyway and it is not a real easy pick on a 6 pin model.

soooo... I took shoe's idea and exploited it and made it different slightly..

the tubular part I am thinking would work like a small Drumm Geminy....

what do yeah think

ohhhh and copyright me.... take it and i'll kill you
