Hi Martin,I'd be happy to look at your horn theory. In fact, I had planned to do that when you mentioned you were working on it, but I didn't know you had finished and posted it. I've been so busy lately that I haven't seen much outside of my own sphere and it's time I corrected that. So I'll look at your new work and I'm pleased to know it's there. You do so much for the DIY community, I know everyone is greatful.
In fact, I think I'll go have a look right now, find the link and post it here so that it makes future reference easier. When I have some time to study it, I can always refer back to this post.
Thanks as always,
Wayne
