Home Made Ruko Challenge Lock

[Papa Gleb]

Wanted to share a recent challenge lock I received from my good buddy the Lock Butcher. Notice the plug, it has that Ruko/ASSA cut/grove in the plug chambers. He did not have interest to share this but I couldn't let this sit in the dark as I think this is a very creative idea. Especially at a time now when its assumed that everything has already been thought of and created. Its also hard to see but this thing gives a super deep false set.

Wow. Those deep grooves in the core look like they could be nasty when they catch the end of a spool. Any idea how he milled them in?

Thanks for the nice write up! On this one, I cut down the length of the plug with a bandsaw and then filed the sides with metal putty so the driver pins wouldn't catch on the gap in the sides of the plug. These are cheap 5 pin cylinders and haven't been too much of a challenge for the folks I've sent them to so I decided to take it up a notch and use 6 pin Sargent and Russwin cylinders which are drill resistent so the plug is not able to be cut with a bandsaw or hack saw very easily so I used a Dremel with a cutting wheel and plunged it into the side of the plug and got the same effect but only on around 4 of the 6 pin chambers. We will see how it goes.... thanks again Papa!

That looks incredibly fun. Nice work.

Doses this lock have functioning keys? I am not familiar with "metal putty" but it just sounds intimidating. Very interesting stuff. I would love a video of the picking procedure, because it seems pretty overwhelming to attack.
