From what I have read about you the T-Hook design it looks like the prototypes have been made out of metal for obvious strength reasons.
I was wondering if someone with the 3D files was able to run it though any stress software and figure out what loads we might be expecting?
I am looking to plastics as being a possible material for the T-Hook for a low rate initial production. The reason I am looking at plastics is that is what I have experience working with and once a mold is made it is easy to reproduce for a fairly low cost. Does anyone know what Tensile, Flexural, and Compressive Strengths we might be looking to achieve?
In the meantime (the T-hook idea has been here for really quite a while now) there is (a) the V2P and (b) the Retro.
Best to try these first.
The V2P has an interesting history. It amalgamated from a range of really old and old ideas, plus it has some nice new features - some of the older ideas resulted in me submitting a feature request to Otto Bock, when 6 weeks later or so they released what appeared to be a mini series of a product called MovoHook 2Grip - an interesting but wiggly product whose features I published on the web right away. A good year later, Brad combined best of all features also of the T-hook into the V2P. It is indeed quite an anchor but it really works well, and I really like it. I laid hand/s on a Retro recently but (long story) have not tested it yet.
Good to know that a similar design is out there and working for people. The V2P looks very useful to my novice eye.
