Well done to Mick for the very interesting demonstration on Node Joints (and posting the image from Harrogate last year)

Because of the very unusual and rare subject there is almost nothing on the internet on Node Joints (and, as it is Mick’s title I have thought of every other permutation of this) So if your german is up to it then enjoy the Youtube video here  –  https://www.youtube.com/watch?v=algwtQYqfu8  

It does not however show how to make the joints that are not through and through / pipes in line with each other.
