I will take some and post them when (if) the deadbeat who borrowed it ever gives it back. It's really not much to look at, though. I filed four slots into matching pieces of 4130 plate and then brazed them into a straight-bladed fork. the slots don't correspond to any exact rake (one ended up being 36mm, another 44 mm, etc.) but it did give me a very good idea of the feel of different rakes/trails. As I wrote, I was pretty surprised at how unimportant the differences were.
