The mouth of the left channel is done.  Now it has the corners are glued in - you can see in the joins between the pans are chorded – you can see it on the first image.  It is left just to finks beefing up the frame – you can see on the second image that I started to do it with one side and to clean/finish the horn inside. In the third image you can see the complete one side of the horn. I use my idea of random beefinization – this is how the whole horn will be done. The concept implies a random combination of 7 elements:

1)      ¾ Baltic Birch +  3x4 studs
2)      ¾ Baltic Birch +  3x2 studs
3)      ¾ Baltic Birch +  3x2 studs that are not shimmed to the frame but buffered by polyurethane foam
4)      ¾ Baltic Birch + ¾ Baltic Birch
5)      ¾ Baltic Birch + roof cement
6)      Small open sells of ¾ Baltic Birch
7)      ¾ Baltic Birch + sand (atop of the horn)

All together the surface sound much heavier then 1.5” of Baltic Birch. It is a lot of labor to do this but I do like the result VERY much. It does look ugly but it was exactly how I warn it to be. My carpenter feels the I am crazy as he things that we will never lift it up. Well, fuck it, I do this horn once in my life and I would like it to be done “seriously”.
