Stone Sphere Machine Build Part 2

[@Dr.Reason]

Honestly, everything about this machine is pretty self explanatory except the cups…that you didn’t show how to build. A very cool design and build. Thank you.

[@baddestmofoalive]

I would strongly recommend adding a GFCI pigtail to the power cord. Having exposed 120 V terminals and switches underneath an open tub of water could turn ugly pretty quick. I would recommend either getting liquid tight connectors for everything, or At a minimum, getting liquid electrical tape and coating every exposed bit that is carrying power

[@andytus]

Not only a gfci pigtail, but a waterproof enclosure and a couple boxes. How this is set up is a strong potential to start a fire and at worse kill someone if you grab it the wrong way. The machine itself is a good idea, and I'm going to build one, but I am going to do better with the electrical.

[@TurnerMillsDesign]

@@andytus Electrical clearly isn't his thing. Awesome build otherwise. I hope he gets it redone safely before he sees the magic pixies.

[@TreDeuce-qw3kv]

Logical design and build. Two Thumbs up! A parts link would have been appreciated.

[@andrewnicholson4689]

Amazing process. Lovely results. Stone is awe inspiring stuff of our histories, over thousands of years. Without it we would not be here probably.

[@umar638]

I've seen videos of your old and new machine running. It's an excellent idea. I have a small suggestion. You use the rubber bands on the screws to create a tension among the three components. If you add a loose pulley on each screw and then apply the rubber band over it, you won't need to check the tension manually every now and then. Each pulley on all the three screw will distribute the tension equally everywhere.

Can you add a parts list to the description? Thank you!

[@rob3942]

Good inventiveness and info, watch the electrics around the water though. Thanks for posting your work, love the rocks, all the best

[@justd3fy]

Can you make an update video on your current machine? This is fascinating. Glad I stumbled upon this

[@MrFizbit]

a materials list and possibly where to buy would be awesome

[@Tenneseejosh]

Ive used a lot of your ideas in building my own machine as well as using an idea of putting the grinding segments on with velcro. I've used windscreen (windshield) wiper motors because they are 12 volts for safety around water for cooling. Ive also gotten stainless steel motor mounts cut from 2mm sheet. The brass adapter fittings are 1 ½ inch flanged blanking plugs. They have a tapered shaft attachment to mate them to the windscreen wiper motors. I have high hopes for this machine. Thanks for the inspiration.

[@pebble-ology1845]

That’s pretty cool of you to make a machine. I have newer videos of new motors I’ve been using lately for more speed and torque incase your current motors give you problems. Have fun

[@Edelsteinkugel_Manufaktur]

Another tip: Instead of sticking the pad directly onto the cup, I would first stick on a Velcro strip that had been cut to size. Then changing the pads is child's play and you don't even have to unscrew the cups. At least that's how I did it on my machine.

[@stefanbaumann9226]

Hi, from your name you seem to be European :-) were do I get the material for the cups in Germany! Looks like pluming stuff... or do you have a totaly different solution?

[@Edelsteinkugel_Manufaktur]

Why do you use AC motors and not DC? It would be a little safer because of the water.

Parabéns! Grato por compartilhar seus conhecimentos! Acompanhando seu canal, aqui no Brasil.

[@franciscodossantosferreira6353]

Olá meu amigo, parabéns por seu vídeo; muito legal. Só queria saber onde consigo esse material para construção da máquina?

[@armedmariner]

Best switch scenario has the switch mounted inside a shallow box. 110v exposed terminals is not good.

[@doctorwu1303]

Please incorporate GFCI protection or at least tell people who build this to. This is a great machine, but could kill someone..

[@jimdewael1269]

do you have video of new machine in action

[@roydoucet7697]

Very informative

[@michaelkintop965]

Do you have a video of it running making a sphere?

[@RoomEscapes]

Can you also show us how you built your watering system?

[@kengeohegan6854]

I'd be interested to hear what diameter spheres the different size cups make.

[@Chicchan484]

Excellent!!!! With obtain the design and specifications of the engines??

[@pebble-ology1845]

I would recommend looking on Amazon for small AC electric motors that have good torque. I have found that motors that have a gearbox really helps. I also recommend that it can produce more then 100 RPMs.

[@RoomEscapes]

Where did you get the cups from?

[@flintlock42003]

Yes, need details!!!!

[@pebble-ology1845]

Lowes hardware store

[@Blueknight1960]

A little tape on the shaft (Tighter fit) of the motors will get rid of the wobble.

[@MrPaulg1971]

Love the machine built one myself from your video. Have you produced any spheres off of your new one ?would like to see it running.

[@michaelkintop965]

You made one? I’m in the process of making one. Have you had success in making a sphere?

[@michaelkintop965]

@@MrPaulg1971 have you found a different motor to replace? All the motors I’ve looked at are hi rpm’s, too small, expensive, or to big. Maybe Amazon isn’t the place to get motors…? I did get the 110 rpm motor non geared.

[@MrPaulg1971]

@@michaelkintop965 I've looked but like you said they are higher priced. if I'm going to upgrade the motors then probably will upgrade to metal frame instead of wood. need to compare price with time and materials with highlandpark sphere machine they are $1300 +tax free shipping

[@koespermatakhaira68]

can i buy your product like this.

[@IrfanShaikh1]

Which motor we can use

[@billrichardson2256]

👍

[@zenmonkeyman]

You casually mention in a subsequent video that these motors didn't work out. Maybe add something to the description so a bunch of people don't waste their money buying the same ones

[@WildTrek]

Thank you for this comment 😂 I wonder how many people watched the first video and ordered those same motors 😬

[@JulianMakes]

Oh thank you!

[@darylefleming1191]

After building this 2 years ago, would you make any changes on a new build?

[@pebble-ology1845]

Yes. This is a question I get asked a lot lately. It may be worth diving into my new macho and explains the trial and errors and does and don’ts.

[@rayclark7963]

Come on dude, are you trying to start a fire and or fry your self like a hotdog?
