Yes, the cylinder is a magnet. The white things are the bearings, I think. I believe that I want to hold the bearings in the vertical axis. So, I can spin the magnet in the horizontal axis. Honestly, I have no idea what the RPM's will need to be. And, this is not part of a structure that will be...

I found perfect bearings for spinning this cylinder horizontally. But, I don't know what to use to hold the bearings, vertically I think. Can someone please try to tell me what I should use to hold these bearings?

I won't be able to tell you everything you say you need. Because I fear that someone might steal my ideas. But, I can answer some questions. 1. I can't tolerate any vibration 2.+3. I have no idea what the RPM will be. I might be trying to use a cordless drill to spin it. But, nevermind.

Thanks for the idea of using bearings. Hot dog rollers won't work for this project. But, I found perfect bearings. Now, I am wondering how I should have the bearings held to be able to spin the cylinder precisely, with NO shake. I might use some Loctite to secure the bearings to the cylinder...

I believe that a bearing may be a good solution. But, how do I attach the bearing to the cylinder?

I am not a great artist, but I drew this on my Android phone. The spin I'm talking about actually has almost NO movement. I asked my brother about it, and he said that I should put it on something like a rotisserie.

Thanks for the scientific response. Aren't question 1 and 2 the same? I think I should say that I need it to spin on the vertical axis, if it was standing up. The horizontal axis, if it was laying down. But, I usually say: "Iimagine a pencil laying down, and spinning it on its own graphite."...

The dimensions are 6 inches long, and about an inch diameter. How do I lay it down, and spin it precisely, with absolutely no shake? I understand that I need to know the exact radius, and find the center of each side. But, what do I do next?

Good answer, thanks. You might even be able to help me with my main question. I'll be creating a new topic for that. [Mentor Note -- No, your two threads on the same subject have been merged. Please check your PMs. Thanks]

Thanks. You were absolutely correct. I didn't realize that the Summary is basically the same as the Title.

Imagine laying a pencil down, and spinning it on its own graphite. What do you call that, "spinning" or "rotating"?

Can you please try to help me with posting a question? I keep forgetting denied.

Thanks. Me too.
