BTW, if your joint if off for any reason, you can plane it true by adding a few shims under either end of your work-piece (against the fence). I keep a box of outdated business cards just for this purpose.Thanks for this @BentonTool. I have some more framing to do around the house, so will take a look at this more when I get around to those projects. I haven't really looked into shooting boards yet, but they keep cropping up so it's probably about time I investigate.
If you build furniture with hand tools, a shooting board is a God-Send. You will wonder how you ever got along without one.
