I'm actually patterning what I'm doing after that.

25 bucks for four pieces that are very big and have no place to go underneath the chair. Very tight mechanical space there. And I need a jack and a hoist to put the chair on its side to work on it. This thing will kill me if I'm not careful. Literally, it will kill me. I've only seen the underside once 3 years ago so I'm working from memory here.

Keep in mind that I bought these particular roller balls on a whim since I knew there were many uses for them in my kitchen construction. Internal to cabinets and drawers everywhere by the time I'm done. The little ones. But then I saw the big ones and thought of other uses.

So when I had them in my hand I looked around and thought of the various things I could do with them and then saw the chair and realized and they were a requirement at the bottom of it. And then I looked at the refrigerator and realized that when I pop it on its side and on its back they're going to be required. But not permanently. Then I look around all over the place and I realize I have a high use case for them.

That drill press is really heavy. And I don't want to be tripping on those big wheels and stoppers as I'm walking around. Every time I look around I think about the walk path and me tripping and then I add to it the fact that I have heavy machinery that I will be moving around.

A piece of wood ain't that heavy. Start adding them together and they get very heavy. Slap these things on the bottom and nothing is heavy again.

To start off with I'm just going to create my own little dolly. A foot by a foot with them on the corners. And then I'll create several more. Some with nothing more than 6 in by 6 in of four wheels on a board.

Whenever they will be used I will double-sided tape the board side to the large object I'm moving. Put multiples of them on a single large object for rock solid firmness on movement. And then I will rip them right off and use them again.

This guy has shown me uses for double-sided tape that will live with me forever.
