Uhto! I think Agena sells those!

(Glad I'm a democratic-socialist!).....

I was lucky. I didn't catch the "Tool-Bug" until I was around 21, and was very into bicycles - just to rub mud in the face of a certain idiot who claimed he was the greatest mechanic ever hatched! With an incentive like this, and a long trail of friend's of mine having their bicycles & cars destroyed by this 'genius' - I set off to Oregon to the United Bicycle Institute, where I was one of their first students. Excellent people and tons of knowledge to prey upon! And thus I caught the 'Tool-Bug,' with a set goal in mind.

I fixed all those people's bikes and showed them how to use 'Zen and the Art of Tool-Use.' They then fixed their own cars! I'm still of mind to believe there's only one appropriate 'Fix' for a car:

- HONK! HONK!

So of course your home-brew OTA-Rotating Rings & Pdf. brings accolades from the likes of me & my band of Merry Pranksters! (People warn me I should come equipped with a Splash-Gard® & Thesaurus as standard-equipment for talking with me...) So please feed & nourish your 'Creativity-Bug' daily. I only hope it's it's a "Catching-Disease" like smallpox or the pneumonic-plague. But only lethal to fascists.

From what limited perspective allowed by your how-to images you added, it looks like you have a very good lay-out of some very cool tools. Mine are scattered about my workshop/storage-space/futon-pad/optics' lab. Having a photographic-memory (which everyone does, but the public schools punish their vict...er...students for using) helps to make for ready access.

In the Boston/Cambridge, Massachusetts area (for one, I'm sure) some mechanical-folks have aquired a warehouse-flat in which they all store their tool-collections. New people are encouraged to join with theirs and share with all. And hold teaching-workshops to show any & all how these all work and are applied in such by demonstrations. I think this is a wonderful idea! I've been thinking of organizing a similar gig up here, but I'm forever being side-tracked by this, that, and just plain BS! But it's at least worthy of spreading around as an idea in search of nest!

So do carry onwards & upwards with your projects, and please to keep the camera ready,

Dave
