I’m late to the game here… but man, I’m in awe… amazing job!

Congratulations !

Fantastic!

Omg! That's amazing!

Félicitation, c'est fabuleux !

complimenti davvero un' affascinante e magica opera! :-)

Love the linkage.

Brilliant! So smooth and life-like. It's mesmerizing!

Yeah, it worked out way better than I cold have imagined when I first started work on it.

Congratulations. This is a beautiful machine/movement which makes use of trajectories obtained by fully understanding how a rotating crank working with rectangles, levers and rombus with a variable geometry can achieve such motion. The difficulty is to get the extension to go to the the capture and delivery destinations with a transfer sychronisation in between. The result is almost hypnotising, I feel that the future of art is through dynamic art as the paintbrush and photographs have their days and while videos are a good media, the future is with technology and mathematics contributing to artistic pieces, Well all machines have a rhythm of their own and they are just like musical harmonious pieces. Well done , and it is remarkable to think that most of the movements in this artistic piece are found on cranes in dockyard lifting tons and tons of materials to make ships. I worked at a Dockyard a long time ago and I always admired the extension in the jibs of cranes and some travel on a multiple wheel arrangement where each wheel irrespective of the level of the ground takes the same load equally. mechanical art is all around us and it is a pity that it is not noticed by many , even educators who should kknow much better. Congratulations.

absolutely amazing, the whole rig works seamlessly and the perfect timing of the ball returning is also fascinating, it must have taken you a lot of time but amazing in the end and looks like a quality build.

I need to thank my dad who said something like "Why not use less track so that the focal point of the sculpture is the mechanism?" before he said that, I had planned on a bunch of plant-like shapes and organic looking track.

Maravilloso mecanismo

Absolutely gorgeous. Elegant. Question: at the pivots in the linkage, is there any kind of bearing or is it just a smooth pin?

On the larger connections, like on the motor crank, there is an inner shaft, a middle bronze bushing, and then the outer connection. You can see those on the end of the motor crank and where links connect to the frame. The other link-to-link connections are just done with steel-on-steel pin connections. Where you see a link with a single rod and it has another link that goes on both sides of it, the outer link has round tubes at the end that are just large enough for the screws to fit through. Those screws screw into either side of a small short threaded tube that is inside the end of that inner link. That way, there are no washers to deal to keep a long inner pin/tube/bushing from sliding out the end. of course, it does present the problem of how to get a screw out if it's threaded into a hidden pin/tube/bushing!

Superb David . You deserve a standing ovation. I cant believe my eyes .What kind of motor is it, rotating at such lowest rpm without even a gearbox?

The motor has a built-in gearbox. It's going at 2 RPM, or maybe it's 3. it is a Bodine 110v gear motor that can be bought on eBay for about $50.00 new. Used motors like that range in price depending on age and how much noise the gears make :)

Wow!

Awesome, could you speed up the mechanism a touch or make the track a bit longer (better of the two) so that the pick up arm is timed to pick up the ball just as it arrives? I just found this program and cant wait to get my retractable grill shelf designed and fab'ed up!

The motor is a synchronous AC motor so the RPM can't change. I can't really change this specific mechanism since it's done and on display now (on my bookshelf). I'll keep the timing idea in mind for the next one I build.

Have you got this one done up in Linkage by any chance?

open blog.rectorsquid.com/sample-linkage-mechanisms-2/ and find the mechanism called "Ball Lifting Mechanism". Let me know if you have any trouble getting it.

@@rectorsquid Yes, that's the one I've been working with and attempting to model up to create in wood, (copy shamelessly) and trying to incorporate the 'straight' lift one with also. This one in the video appeared different to me for some reason. DXF export has been working well for use with a CAD program, still trying to iron out slight interferences. Also, there does not seem to be any memory leak issues in this version.

Awesome! Nice work. I'm impressed. P.S. Sell me one! I'm not quite the brain or the fabricator that you are to make one myself, but I'd definitely stare at it for hours. :)

I would love to sell these things but it took me a year to get this one done. But you could contact the guy who made this video: kzread.info/dash/bejne/g4l2vNlmis3SYqg.html He designed his laser cut kits from my plans. He could at least make you a wood kit if you wanted it.
