I have had a couple questions about my block. I drafted it in 1999 at a retreat. I finally found my not very professional draft and am posting it here because I can't find a way to put it in a PM, I hope that's okay. We used coloured pencils for the different angles etc. & erased some to make the blocks less complex. [ATTACH=CONFIG]453761[/ATTACH] I have my block turned a little compared to this drawing.
