About the CLThis was first used in the video on how to create a practice lock: Then I modified the drivers, key pins etc to turn this into a challenge lock. As it’s a double euro cylinder, I left the other side untouched for comparison. The same key operates both sides.

The grub screws can be easily removed with a metric hex wrench. Please don’t put them tight as that is not needed. I didn’t have an extra wrench at the time of sending it around unfortunately. You can file one if needed, use pliers or worst case cut a groove in the top for a standard flat head screwdriver if really needed. If you insist on a traditional gutting, you could use the core as follower or segmented followers as well, but that’s a big hassle with a double euro cylinder. [spoiler alert] A shim is probably not needed on this lock.

For all the details of this lock and the ideas behind it, this video covers the lot:

Note the tapers and reduced diameters to help with the correct orientation in the lock.
