As we have planned we continued with the corrugated sheet aluminum. Reinhard has finished last week the tool and made an impromptu test with two screw clamps. It works.

View media item 58515The two parts of the corrugation tool were installed to the front of our big press.
View media item 58516Here you could see it in detail. On the right side we installed a type of counter bearing, made from planks and a piece of rubber to prevent the press from unilateral erosion.

The making of a corrugated sheet:

View media item 58519Before the second pressing. We have to turn the sheet for every step. So the last valley is then a back.

View media item 58524Testing the stability. Both are AlMg3, 0.6mm. On the left a 200g, on the right a 1000g hammer. Ok, you need a little bit more square centimeter sheet metal for the corrugations. But the result is much stronger.

By the way, we published 855 pics in total in the last three years. That means I have only 145 pics for the future. That will be a problem when I try to show the next steps in detail. Any idea?
