IMG_9877IMPORTANT UPDATE!! (2009-01-13 @ 13:59:03) Do not double the rope/cord! The rope can be jammed because of  twisting and entangling. Use just one run of cord.  ~30-35 (the “working” free end) should be enough.

I will update the manual ASAP.

Just published the description of my new DIY ice padlock. Opinions?
