Hey Rob,
That's cool. That'll work. I'd like to have something that has the "blade" slip into the cavity of the reference. That way I could have a reference on both sides. I can see myself flipping this thing around a lot. The picture that I looked up looks like the nut might be a little proud of an edge also creating a problem with referencing. Could be the picture, but I can't imagine them designing it like that.
p.s. by the way, welcome to the conversation.
Thanks
