Re: high security foil impressioning
One solution would be to make the comb keys from standard steel key blanks and possibly thin them down a little by fly cutting. So we really need a milling machine for cutting the slots and the thinning operation. I know that people do break blanks while impressioning (mainly soft brass), but have a feeling that , it might produce a longer lasting blade. If the spare blades were available at reasonable cost, then one would not have to make them, or even buy the tool set, as it would be easy enough to make a handle.
I think as impressioning progresses, it would be nice to purchase a UK version, if one could be produced at reasonable cost .... which I doubt.
Last night I was wondering about modifying a comb pick, but that would not work because it would never go into a Yale Y2 key way, so fabricating the blades from key blanks appears to remain an option.
I wonder what the UK suppliers could do about this ?. Would it be a viable product ?. Direct impressioning does have the advantage that a working key is the end result.
