Just a note on Dorma SFIC cores.

Cut keys and pinned up a couple Dorma SFIC cores for a member, and wanted to give those of you who want to do the same a 'heads up'.

The size and shape is the same as any SFIC (give or take length for number of pins).



The depths are like any standard SFIC. But the spacing is very different.



So you will need to measure and use a micrometer card with a code cutting machine to cut working keys.

A key punch will put too much spacing between each bitting, making it progressively more off.

And tip stop? Awww, who needs it? Sure, proper Dorma blanks for these would be tip stopped, but the owner of these cores found another key blank that fits. So these are now shoulder stopped.



Where there is a will, there is a way.





So if you are going to play with Dorma, be careful of the spacing. Kaba Peaks is also different from Best and Dorma.

Have fun, people.

Nice work Gordon, KM was able to make keys for one of my Dorma cores a while back using Sargent blanks.
On the subject of Kaba Peaks - they have both .140 and .150 spacing.
.140 is used if you have mortise, rim, KIK and SFIC in the same system, .150 is standard SFIC so you can use the tools for Best cores.

Looking prettyyyy sexy. Even has a nice ring to it Sargent Dorma lol.

Thanks for that data, Jeff. The only ones I have tried to make keys for happened to be a mortise using an existing key (now, due to your info and how the pins did not line up, pretty sure that key was for standard SFIC, but matched the keyway) and a SFIC that did not match up with Best, so that SFIC must have had the .140 spacing.

Of course I'd have to get the mixed-up ones.

I have a Kaba Peaks LFIC for Sargent sitting here. Don't feel like digging out the calipers though.
