aussielocky's Chubb detector lock video on YouTube

[greyman]

This is an interesting and instructive little video by aussielocky, an LP101 member:

It shows an 1827 Chubb 4-lever detector lock in operation.

Cheers

That is a great video, and why aren't locks still made this way, or are they.
Somehow that guys accent does not sound 'strine' or 'stralyun'

[cjames73]

cool, thanks greyman.
i've seen diagrams of this lock before but this video explains the detector much better.

Has anything like this been done with pin tumblers?

It actually seems like kind of a gimmicky feature (as much fun as the mechanics is.) Can anyone name a good application for this sort of thing?

The MLA Binary Plus, designed by the Master Locksmiths Association (Australia) has adapted the idea of the detector mechanism into a pin-tumbler lock, although it's not exactly the same. You should be able to find a diagram online.

Great vid - enjoyed it a lot.

Compact little thing isn't it

I assume aussielocky = oldlock from lp101 too (just recognised the youtube account name from posts i have read)

Anyway thanks for the video, nice old lock in very good condition for its age too!

The S&G video was interesting, thanks for that too.

thats some high tech stuff tor th 1800's.

and that Binary Plus lock looks like a nightmare!

[Gordon Airporte]

Thanks for finding the graphic zikmik. That looks like a challenge to pick, but I suspect there's a fairly straight-forward way around the secondary locking mechanism. The wider keyway practically invites people to stick tools in there. It's entrapment

BPA is a great product....and totally bump resistant without prior knowledge....but can still be picked (although not easily), because light tension will still allow the pins to bind on the shearline.

Also, many of the MLAA members generally dont use all the side pins and the 4th (or 5th, from memory) can only generally be a maximum 5 depth (out of 10 depths) and cant be master pinned. This reduces the number of change keys in a master system.

Being a restricted keyway is it's greatest advantage. The fact that the manufacturer has a legal agreement to only sell to association members makes this a worthwile product for members.

From my understanding....the side pinning is usually a dealer code?

Most of the Binary Plus' that i have handled have either a single side pin and trap or all of them. Some also take advantage of the restricted system and use the cylinder without trap pins/springs though i have only seen this once or twice.

Not as I understand the product. There are 3 profiles BPA, BPB & BPC. A plus are available with the trap pin on the third chamber only or on all. B on the third only & I've never seen a C.

Where you load the trap pins depends a lot on the cuts of the key, which in turn depends on the complexity of the MK system.

I've just done 2 more video clips. I will leave them uploading & head to bed now. They should be available to view in a couple of hours I would guess ...

that video on the paurotoptic lock was very interesting.
