A New Challenge. Number 2.

Challenge Question No 2.

You are on a job that you must finish and cannot leave until it is finished, and you then receive a phone call from a man saying that he's got a broken key to his mother's house and he asks you if you can repair his key? You say "Yes" so long as he can bring the key to you. He agrees to that, and five minutes later he arrives with his key, the key turns out to be what is left of a 5 lever Union mortice key. The problem is that the first three bits are missing off the key. Your task is to rebuild the key. This man is in a great hurry as he has to get his mother to hospital quickly. You have a mortice key cutting machine but no measuring equipement.

The question is:
Can you construct a new working key accurately?

Well a bit easier than the last one :wink:

. This sort of thing is quite a common problem on chubb keys if you have low and high cuts next to each other. The first part of the key gets knocked on the keyway over time thus bending over the first part of the key. The key works from the outside but wont work from the inside so you have to .........insert same method chris is after :twisted:

in the magic world we often get told, "it's all done with mirrrors", so i'd find the answer in "abaracadabra" but not in "hocus pocus"

How would you get the cut depth for the 3rd (middle) bit? Maybe look at where the metal was broken off and compare broken metal with smooth metal?

The third cut is generally not the middle one, 5 lever keys usually have at least 7 cuts ..

Oh, thanks for correcting me. :oops:

One part of the key has to lift the levers and the other part throws the bolt, yes?

omg, this is the first time i've seen this thread! :oops:

reading through i actually worked out that the key could be reversed, but i've never used a key cutting machine or had anything to do with chubb keys or anything, so i wouldnt know how to answer, lol.

Same solution, lazier idea...

Why not just make the key up in your pin and cam (if you have one) and cut from that?
