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.)
