You have to stand really close.
We were just mucking about with stuff, I'll have a look at the pictures, can't remember if I took pictures of that or not.
But the jump from 1/2 inch to the 3/4 is a lot more than you expect.
I have a sneaking suspicion that the 3/4 inch uses thinner sheets of wood and the extra lamination is what makes all the difference.
But I never looked or checked, so that could be nonsense.
So I'm guessing the next video is an impact check on an 'arm'

Gobble gobble ?
