routed technique I'm working on.

This may be hard to explain. I route 16 (in this case) V grooves in the end grain of 2 pieces. They seem to fit perfectly together. However when routing straight across the bit cuts tapered V,s so the middle is lower. It looks kind of like an orange squeezer you use to make orange juice but concave. When you put the two together only the outside is really glued unless you use a gap filler type of glue. Of course then you can't reduce the size very much or the glue gap shows.
I rotated the router guide to about 8 degrees and then you still have the tapered V,s but now the middle isn't recessed. However now the outer edge won't seat because the middle is touching and the V,s are really shallow. I still glued one together with colored epoxy and will try and turn that tomorrow to show you the results. The gap looks pretty cool.
So I tried rotating the table about 2 1/2 degrees and then hollowing the middle. As you can see in this photo there is still a gap on the inside due to the tilted V,s. I'm going to go back and try the 8 or 9 degrees tomorrow but hollow out the middle and see if I get at least close to a closed gap for 1/4" or more. I was hoping to get it all the way to the middle but that won't happen.
As you can see in the first photo the outer edge meets perfectly. However just 1/2" in you can see how large of a gap you get. That's with the table swung 2 1/2 degrees from the outer edge toward the middle so the router is routing a tapered groove. Well that's not accurate because it's always tapered but this way the middle isn't as low as if you route straight across.
