The walnut was refurbished 5/8" boards. So i had to cut them to 15 degree and pair up two pieces to make 30 degrees. Then the Oak was cut to 30 degrees and i cut the slots in the Oak.
After glueing it together 3 times because of not getting the parts straight i ended up slipping a wood dowel in the middle as it kept wanting to not stay tight together in the middle. Big rubber bands to hold it together and 24hr dry time.
In the end I won.
