Home Made Ruko Challenge Lock

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?

Re: Home Made Ruko Challenge Lock

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.

The code is hidden in the tumblers. One position opens the lock, another position opens one of these doors...

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.
