Greets folks!! Hope everyone's doing .... pretty okay at the very least! This video is about over-centers (latches, clamps, you name it). I've got a couple in the can coming soon but next vid will be welder winners. Sorry for the delay! (still love you real-time, though).

Over Center Mechanisms But Were Afraid To Ask!

Good manners and over-center mechanisms are what separates us from the animals. Let's talk way too much about them! ------ Music: Wayne Jones - Mr. Sunny Face / Silent Partner - On Hold

I did not plan to learn anything today. I figured I'd eat some chips and watch some vids. BUT! Then you come along and teach me stuff in an amazingly entertaining manner. Thanks heaps. No, really. Heaps!

Brent Stultz

Always happy about another video! Learning or not lol Although my wife seem to like you more....... Wait a minute...

Brent Stultz

Damn those beautiful hands...

Your vids always get me excited like a kid... Back to the workshop!

I must say, Tony, this has definitely given me some inspiration for a future video that I may or may not produce.. amazing content as always.

More ToT videos = More joy. Keep the dad jokes coming.

Its amazing to me that we all love your videos so much that you can make a video about a mechanism arguably nobody cares about, without even using that lesson now in a project build of your own, and all of us are just as happy to watch it as when you mind controlled an old rusty German, and gave us the full movie step by step of how you did it. Im truly not being sarcastic either. I now want the ToT re-narration of every episode of How Its Made / How It Works.

Kyle Wellman

Also im not sure why i just thought of this, and im sorry if you already have, but i would also really enjoy buying merch from you that would depict a potato with your iconic hands grasping your mythic color changing sharpie with only the words "Tater ToT" above it.

Kyle

Your videos are gold. Pure gold. Thank you.

I appreciate how your occasional ... unique ... machining techniques have become sufficiently entrenched in your style that you can now just toss one or two of them in, casually and offhandedly in a blink-and-you-miss it sort of way. And the fact that you can still come up with new and fresh ones floors me.

always a pleasure :)

Thanks Kyle! that's reassuring to hear. Halfway through I actually almost canned this video thinking no one would find it interesting. Glad to hear I was wrong!

I definitely found it both interesting and educational. Even though I already understood how over-center mechanisms work, watching your explanations and examples gave me some new connections between things I knew. Some of that was the things you said, and some of it was from thinking more about your example mechanisms while you were explaining them. A particular example: When you were building the screen door simulation, I was thinking about where to put the mount for the spring on the door, and realized that it should be centered on the line between the hinge and the fixed spring mount when the door is at the desired "no force either way" point. Which seems obvious but I had not thought about it that way before. Also, I think there actually is an over-center mechanism in the tic-tac box lid (or similar) that you showed, in the little tab latch it has. The spring is the compression of the plastic as the bulb on the tab gets pushed into the slot and then its expansion as the bulb gets past the tightest part of the slot and it widens back out slightly. On the ketchup bottle lid, I think one key subtlety to it working is that the plastic springs aren't straight and don't stretch, because that would be too much force (and too much stretching for them to repeatedly stand up to). Instead, they're curved slightly and pulling on them straightens them out.
