Matching rabbit(or grain) with wedge sled.
Dec 20th, 2016 at 7:52pm
 
I normally recess the bottom ring in a vase for a solid base on the lathe after it has been glued. I though  I could make a rabbit cut in the wedge stock so I could insert a solid board in the base (either glued in or free floating.) instead of cutting it on the lathe.
Here is what I did.
Cut a rabbit in the wedge stock where the bottom insert is placed. The rabbit can be seen next to the fence.  I used the table saw to cut the rabbit, but next time will use router bit.
1) Cut the waste on fence 1 of sled.
2) Cut a good wedge on fence 2
3) Repeat step 1 and 2 in order until all wedges are cut. (two wedges shown with waste)
4) ring ready for glue.

Pet peeve,
It's a rabbet when you cut it into your segment stock.
Once the segments glued into a ring or circle, it's becomes a recess or a type of mortise.

From your third photo, it looks like there is still material left from the saw blade, I'm guessing a high ATB blade. To avoid this, you can either use a rip blade, which would leave a flat bottom to the cut or a router bit as you indicated.

One thing to consider is that when cutting your pieces prior to assembly is that there is more potential for tear-out. This can result in more work in the form of checking edges and sanding (if necessary) prior to assembly.
(you can make a Zero-Clearance fence to match the rabbet)
