Coin Bending forces

[wulfgeat]

I saw some discussion on coin bending, which is something I hope to do someday, and I thought I would share this video where someone does to coins what we do to rated steel.

Maybe, we can use a machine like this to create a realistic list to progress to bending a dime or penny?

That’s kind of cool

Now that’s an interesting idea.  I have never been into coin bending but if we were able to get a rating system going that could help measure progress, I’d be all in.

The best part to me is this guy is able to press the coins back to their original shape at the end of the video. So we could test, flatten, and attempt the same coin/washer/sheet metal disk. 

 

We could also test to failure and see what the average strength is after say 1, 2, 5, 10 and etc. bends and create progressively harder steps that way. So if a penny continues to weaken as we re-bend it, we could pre-bend our pennies to different resistance level steps to work our way up the ladder from the weakest pre-bent coin to an unbent coin.

 

I feel like this could be an interesting hobby to say the least.

If only someone had the machine. I wonder what something like that would cost.

It looks like the gage itself is not cheap:

And we would still need a test stand.

you are right, it is not cheap.
