I think this is a fair summary. No one can know what you experienced, but it sounds like you bent a screwdriver, the drywall guy bent it back, and you were very hot and frustrated.
Tools made for prying aren't usually "hardened".
Don't you think the drywall guy would have been impressed that you could have bent a "hardened steel" driver and slightly dumbfounded that he could unbend it?
Did you save the tool?
It wasn't meant for prying, how could I explain this to you?
I'll try.
It was perfect for Mechanics and I had it in my tool belt for taking down electrical light fixtures and such.
What was going on is that chisels for some reason would fall out of my tool belt and I would have to walk around and waste time looking for them,
so I would use the driver when that happened and find the chisel later when I had to walk back to the truck for whatever reasons.
The upper part of that J channel is about an inch longer than the bottom so that you could screw into wood like a truss except that there wasn't one there,
so like my porch in that picture it was screwed into the wall in my ceiling the beam, this makes it more flimsy than it should be and more delicate.
That was the reason I replaced it once, if you are applying to much force, it destroys the J which is what is expected.
This is what happened once during the application as I explained I destroyed the J that is what is expected.
All I was doing was sliding it back and forth sideways to open up a slight gap like the picture shows.
The metal turning to "rubber" just cannot have happened.
It did and I should have said rubber like.
Just like you said it couldn't but it did. I dropped it because it freaked me out.
To do what it did it should have been hot and by that hot enough to burn you if you weren’t careful.
What I realized after it happened and I dropped it that it wasn’t, because the drywall guy picked it right up and wasn’t affected by any heat.
To get it to be pliable to the point I seen would have required a application of flame by a torch or one of those small tank torches that sweat copper together.
There's no way that a thin piece of aluminum J channel could have held up my weight and pressure with out breaking and bending open long before bending could happen.
Even if I put that particular driver or one like it in a vise and applied pressure to bend it, it would not have acted like that and I doubt I could have bent it so extremely, it probably would snap long before I could reach the point of angle that it did.
I may even make a clip/movie to demonstrate that and probably if I can’t bend it will show you how it looked using a torch on it at the shop.
but it sounds like you bent a screwdriver, the drywall guy bent it back,
He tried but just bent it back just enough to make it somewhat usable, and I did save it but lost it as I changed trucks out moving tools onto the new truck,
somewhere I lost track of it, I did keep it for a while.
The only way I can get you to understand what I was doing is to demonstrate on my porch ceiling by making a movie.
And I agree with you there’s no way in the world that it could have happened, but it did.
This is a phenomenon that I never believed possible but now, I have to change my mind… at that time I did.
I’ll give you all the factors and information that where going through my mind at the time, as I go through this my memory is coming back to me.
I’ll post this now and write about that when I post a movie, so you can see and understand that we do not know everything about the world and the forces that are in this world or the universe.
One more thing, the metal wasn’t grounded to the earth so I believe that this force was from my mind, I know it sounds crazy but I have no other explanation.
This will take some time.
