Sightline Rule Refined

I've been all over the map lately, but I am home now for a few months and am excited for all of the new stuff that I have to show. First, I'd like to share the sightline square that Steve First made for me (us) at Kelly Mehlers. It's a beautifully accurate way of creating the sightlines and discovering the drilling angles for laying out legs mortises etc...
He made to versions, a large legal version and one that fits on normal sized paper that requires a bit of cut and pasting but works just the same.
Here are the PDFs (actually JPEGS)

I've also made this video to explain the use of this tool and a bit about rake and splay.
