Hi Rob. Adaptations of this principle were used to mount gyros in older airplanes; principally Directional Gyros (DG) & Vertical Gyros (VG). Such mounts reduced airframe vibration influences on gyro accuracy.
Hi John. That's very interesting. I can see how that would help in a lot of ways, as you stated. I'm making another version as the first turned out so well. Interesting subject and good simple project for anyone with a hobby lathe. Cheers Rob
Hi Ian. It's a bit fiddly feeding the fishing line through the holes, but provided the centre is aligned accurately it goes together quite easily. Have to be careful not to over tighten the 3 mm grub screws or the line can be cut. It looks awesome on the mantlepiece. A really intriguing piece. Cheers Rob
👍 Good stuff Rob, tensegrity is some clever physics. The wobbliness may have some ppl thinking that there is no real useful place to use the concept but this is the sort of stuff that is used in solar panel arrays in space. Self supporting with maximum strength for minimum mass 🤓 A minor issue tho, in time the fishing line will stretch. When it happens I'd look at the newer braided lines, much stronger for the same dia and nearly zero stretch or maybe some fine stainless trace wire. Cheers mate 🍺
Hi Bill. Yes, the nylon may stretch over time. I will have to see what happens. I did consider using some 20 lbs stainless steel trace wire I had in the tackle box, but went nylon as it is clear. The SS would still look OK though. These Tensegrity designs are very clever for sure. I had never looked closely until I stumbled on the Ebay unit. It looked dead simple to make something similar. A real mind bender until studied closely. Cheers Rob
That looks really nice, Rob, good result. I can't believe I was the only one to guess what it was. Like I said before, I've been interested in tensegrity structures for ages, Buckminster Fuller is one of my heroes. I might make another sphere at some point, they're a pain in the hole to put together but they're fantastic. The one I made back in the 90s was a 30 strut model from bamboo skewers and thread, I had a 1.5m diameter 60 strut aluminium one planned (I still have some of the ally) but life got in the way.
I have seen those before Rob, just weird looking. If you think about it it does make sense, very cool though. Plus you can still use it to put your beer can on 👍👍🤣🤣
That's a great thing Rob. Interesting project. Will make a nice conversation piece. And as Alan said, ideal to put your beer on. Cheers Nobby
I plan to make another version Nobby, with a bit of a twist ;) They do look good on the mantlepiece. Cheers Rob
A real “mind bender” until it “clicks” and you get how it works. So clever. Thank you for sharing. 👏👏👍🥴
You’re welcome 😊
Looks really good Rob. I did not know of these until you mentioned it in the comments of your other video.
It's a new subject for me as well Jon. Quite a mind bender, even when you understand how it works. Makes an interesting ornament. Cheers Rob
Nice job Rob, it looks very modernistic. I wasn't far out with my fishing reel guess, lol. At least there was a connection....Cheers Tony
Hi Tony. Close but no cigar. Cheers Rob
Nice! Thanks Rob! You're always up to something cool!
Thanks. This one is really cool. Brings a smile to my face. Something to contemplate with a glass of red. Cheers Rob

Its counter intuitive! Nicely done Rob. :I imagine one could put a strain gauge on the centre wire zero it and weigh what's placed n the top.
You're probably right. Cheers Rob
Cool project Rob..
Yes. I think it's cool. Cheers Rob
Interesting Rob. Must have been fun actually assembling it

amazing
Pretty cool.

Probly best that I don't mention a Euler's disc then 🐇🕳🤣🍺
Yes, best left unsaid Bill ;) He He. Some interesting physics out there. The magnet down the copper pipe is also a good one. Cheers Rob
🤣 Yep magnets are weird 🍺
That looks really nice, Rob, good result. I can't believe I was the only one to guess what it was.

Life has a habit of doing that. I will look into this a bit more. I think it may be a bit of a rarified subject. Cheers Rob
I have an idea for another one which might be good for a chuckle. Cheers Rob
How fascinating I always thought those were based on magnets, no wonder I couldn't work out where the magnets were :)
Yes, truly fascinating. The end result is awesome. Cheers Rob
If you Google Kontax magnetic Tensegrity table you will see a version that uses 2 neodymium magnets as part of the central tension support.
Very interesting. Thanks for the link. Cheers Rob

Now that's a thought Alan. Cheers Rob
