Of course, if you have a slot on your table for featherboards, miter gauges, and such, you'll want the fence parallel to that. And keeping the fence square wrt all table features is helpful if you are doing something like routing a tapered leg, where the workpiece is held at an angle to the fence, with a wedge-shaped spacer or similar.Ed,
Again you have kicked my brain into gear. I guess it never dawned on me that the fence is in straight line no matter what the angle... duh
Many Thanks....
