And once again we get to wonder what exact knots these names denote.
(I think that C.L. has an Ashley number, #1045.) Given that, as noted previously,
the Lyndy LK is a reverse Fig.9, that it might have some strong test results is to
be expected. And then, the geometries at test time.
And the break points (stitch thread through the cord to calibrate it, if risk of
affecting strength w/Sharpie marker is to be avoided)!?
Well said Dan, I think you have voiced the outstanding issue behind all testing to date vis – what does the name denote.
Re the Constrictor Loop. I do not believe the variant I use is depicted or described in Ashley. The nearest is #409, the Poacher knot which is based on a single strangle or the #1120, the Scaffold which is based on the double strangle. In the test I used the #1120 variant, but tied iwith the end slipped and not the line slipped as #409 and #1120 are. The end is then finished with a gooseneck around the working line.
I prefer this loopknot to the Bwl because it is easily adjustable but once set it is self holding. I have yet to see it fail with the ease of the Bwl. but this cursory testing does indicate that it could be weaker. On balance, I still prefer a weaker knot that stays closed to a stronger one which is prone to undo itself.
Derek,
I had a look at your post regarding your rig to deconstruct knots after the results you mentioned. Could you post what specifications you would test for. I am looking at what fields one could put into a database to record such findings.
By the way , I am going to post another knot which could be useful and looks good as well. I will start a new post for that one following this entry

Hi Oscar,
I am about to post an outline protocol which hopefully will attract debate and go through the process of peer improvement.
I will then attempt to implement it and post the results to see if the protocol should be further refined.
Hopefully, by then we will have established if the Guild will agree to fund and supply reference test cord.
The results will feature diagrams and photographic images which will pose a challenge for your database. Ideally, the database should be accessible via web pages – is this what you had in mind or were you planning a private database?
I look forward to your input and your new knot.
Derek
Derek,
What i propose to do is put together a SQL server database to link up and reference knot encyclopedias, journals and other collections into a central server which is accessible on the web.
What i have gathered about the knotting world is that it is made up of collections and disparate references that contain knots. It also appears that there is a lack of concensus regarding what knot names mean. There does not appear to be a central resource to collate and reference known knots which can list a knot, related knots, existing provenance, nomenclature , articles, abok or other reference materials, pictures and links on the web. My day time occupation involves the planning and design of databases and I can put together without too much effort the structure that we would need to start such a repository that users can contribute to. I suppose you could look at knots in a similar way to the nameing and classification of organisms. Genus phylum , choradata etc. Obviously I don’t propose to know how to classify knots , however, others with more of an idea should contribute their thoughts regarding this. All I can do is make relationships work on a database.
I have already started to lay out the tables and fields needed in the database to establish nice straight forward relationships. That is why I would like to look at your list of parameters to include it into the structure.
I am building this on a SQL server I have at my disposal. When i get to the point of being able to share the data, I will either set up a server myself or if the IGKT has a hosting ISP, then it can be set up there. I would then create the scripts and ftp them to the site.
Anyway, thats the jist of what i intend to do. I think this would be quite a large undertaking and I will need quite a bit of input and guidance on what would be acceptable and necessary to make it successful. The real challenge will be getting the data into the database, but it’s early days yet. I am sure that others have thought of putting together something like this and I would be interested to know what they have done, where they have come unstuck and if any datasets currently exist to import them into a common datasource.
Regards,
Oscar
P.S
I think discussion regarding a database should commence on another posting …
Wow,
I am so glad you came across this forum, there are many opportunities ahead of you – I hope your love of knots can tie you to the tasks.
I agree, a new thread is wholly appropriate, I look forward to posting on it.
In the meantime, have you come across the igkt.pbwiki.com site. A few of us have been working on it to collect together knotting information. It is a database of sorts in so far as the whole wiki can be searched and anything can be linked as required – it is a very ad hoc database without any formal structure. I would appreciate your thoughts on it.
Derek
