Copying old Chubb RKS keys onto new RKS blanks

[Growster]

I have started to experimentally make these from photos, and, oh dear, it is fraught. A comparatively high failure makes the successful decodes relatively expensive. The blanks are already £3.50 each.

Here I have one I made that didn't work. The client then sent his original, but I am finding it hard to copy this with the Lancer, as the blanks do not clamp identically in the 2 jaws. Due to the unusual shoulder, making these with the Keyline mortice machine is also rather awkward.

I would welcome a little chat here about this.

turn jaws round to use flat end may give better grip

Its the wrong RKS blank to start with. Correct blank and it should copy ok.

This is a very interesting comment. I only know of one RKS blank, the one from Duffells. Another one exists? Where to get this from?

There are some on Flebay.

I used to have some of both blanks but cannot locate them so may have used them all up.
