A puzzle of this time-involved magnitude would be best enjoyed if it had a failsafe 'event' mechanism built into its structure, to be able to 'start-from-scratch' at any point in "frustrated" time that one wishes . (ie. when I made my Chinese Puzzle Rings for sale, I used keychain split rings -- in the event that if one ended up with an extremely knarled bunch of rings during the solution process -- one could easily remove the rings from the 'assembly' structure and rebuild the puzzle from scratch, and then start over again) .Richardhttp://www.puzzlegrail.com/CPR.htmlnoreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-2859096923782116392013-07-28T22:45:07.950+01:002013-07-28T22:45:07.950+01:00Wow!

Never seen such discussions for any other puzzle! :)<br /><br />Actually, you can do without any marks: Just peek into the inside of the lock through the slots, then you will see where the gaps in the shackle plate are. All the rivets will have to end up in that position for the shackle to come out, so that would be your goal position. The rest is just analysis of the current position. ;)Goetzhttp://puzzles.schwandtner.infonoreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-23959830409842150262013-07-03T22:29:16.865+01:002013-07-03T22:29:16.865+01:00While the Lock 250+ may seem a bit chaotic at some...While the Lock 250+ may seem a bit chaotic at some points of the solution (because of some reversed layer of teeth in it), the Generation Lock is perfectly regular. You only have to quickly analyze the position, then decide for opening or closing the lock and on you go! ;) <br /><br />The algorithm in the article on my home page may help you with this. :)Goetzhttp://puzzles.schwandtner.infonoreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-26437234707545563322013-07-03T13:40:38.565+01:002013-07-03T13:40:38.565+01:00You have to define a front face and then keep trac...You have to define a front face and then keep track on which side the top rivet starts and move all rivets to the opposite side.<br />Since it is a "Generation" Lock I will literally scratch a mark at the point where I stop the top rivet and then hand it over to my children. <br /><br />By the way loctite could be good idea for the rivetsHuso Tasohttp://picasaweb.google.com/huso.tasonoreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-4871931507102010002013-07-02T20:12:21.013+01:002013-07-02T20:12:21.013+01:00...it would be pretty simple to indicate direction......it would be pretty simple to indicate direction, I think - you could always stick a piece of masking tape with an arrow on it next to a slider... and hope no-one flips it around...<br /><br />...had a similar thought about a mindstorm controller myself ... but it would still end up running for years! allardhttps://www.blogger.com/profile/02137859069894390167noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-37226564900335460972013-07-02T17:58:43.508+01:002013-07-02T17:58:43.508+01:00Two questions come to mind:
