Maybe that’s what I meant with the “Interregnum” post.
This is a 20 tonne hydraulic press, bending 3mm steel.
Nothing too special. Except that the anvil is made of wood.
The bar is 45×45 steel, machined to an 80 degree edge, and that steel bar is pushing into it with all of 20 tonnes. And at the end of it, a nice 90 degree fold in the steel, an not a mark or a dent in the redgum. Redgum is amazing.
I used the wood because I did not have a piece of steel large enough to hand, and I knew from past experience just how tough this wood is. Our house rested on it for 80 years (wooden stumps, changed for concrete due to under ground rotting.)
Another photo follows to show some details.
