Absolutely. $200 is a rip off.

Probably you never tried ;-) It's not that difficult. To simplify things further you can replace the ring part with a rope loop.

Would the chain get tangled instead the bottle? That would suck wouldn't it...

That would indeed. It did not when I tested it. On the other hand, see this post. So, if you are completely immobile (and can't shake the bottle with your bound hands) I would advise to use a less risky method or to find a bottle with a wider bottleneck.

I have tried Ra's design, but used a light chain instead of nylon cord. The chain can and does get stuck. When it does, it is a big problem. Fortunately, I was able to unscrew one pipe cap. But, if I had not been able to reach the ice lock, I would have been in serious trouble.

I haven't had any trouble with nylon cord, not doubled. Currently, I'm using 3mm braided nylon. Example: http://www.rei.com/product/784296 .

Binaryfreedom was talking about a different design: http://www.likera.com/sb/time/ice-padlock2.php

And you mean this one, right? - http://www.likera.com/sb/time/ice-padlock3.php
I would not use chain here.

Yes, please DO NOT double it. Or it MAY get entangled. Actually, the bigger the hole and the shorter the cord - the less chance it gets stuck. You can test it by twisting the already inserted cord and trying to pull it out. I could NOT make NOT doubled cord stuck whatever I tried. Of course, if you make a knot on the other side ... ;-)

BTW, I have another design in my mind. It will be a bit bigger but on the same time even more reliable.

Seen as i finally ordered a pile of stuff off of ebay and will be making something like one of these.

I'm going to try something a little smaller though. I'll let you know how i get on and add pictures too.

Yes, please! That would be interesting!

I couldn't find the 40mm parts here, so I used 1.25 inch iron pipe. You can get pre-threaded pipe nipples (yes, that's what plumbers call stubby pieces of pipe), end-caps and ther rest of the parts in any local hardware store. Used a few layers of electrical tape for insulation. Otherwise, the design, parts and construction were the same.

The iron pipe must conduct heat a little faster than plastic. Mine thawed out in about 2.5 hours.

Thanks for the grand idea!

Next time I have a cup of tea from a van, i will try puting water in the cup with lid on and freeze it. I know those cups keep the tea hot for ages so should keep ice as ice a long time too cheers, Paul

A long overdue update to this thread...

ice lock

Looks like this could be a much more affordable pre-built ice-lock for those who's DIY is not up to making one.

35 quid is indeed much more affordable than what they had before. Add an insulation layer (neoprene? rubber foam?) and you'll get ~3-4 hours. The lock is a bit too long, though - 19cm.
