Well, after much interest in my spline jig, as well as my walnut and maple frames. I first, went and made a little more impressive spline jig.. hahaha While I was doing that, I put together a little tutorial for you guys. :)
Let's start with the frame that I had made in my thread here
Cut 3/4" Maple stock to whatever width you want for your frame. Once cut, go ahead and take a blade's width off of one side, at about 1/3 or 1/2 of your boards width.
Next Cut a strip of Walnut. Make sure you cut the strip both wider thicker, and longer than needed as in the photo. When cut, go ahead and glue up the walnut strip into the inset made in the first step. Make sure as you're clamping that the Walnut strip is flush against the edge made in your maple stock.
Once the glue dries, using your miter saw or table saw, trim the ends of the glued stock so that the maple and walnut are flush.
Now using your table saw, trim off the excess walnut to be flush with the maple.
