Halving with elliptical tenon
I wrote down the size of the CAD drawings of each part and remeasured the wood I cut, to make sure they were big enough and I tabbed each wood piece with the part name.
One of the mistake I made was I did not set the offset for the round joint - I thought they will fit each other coz, they are round...
I sanded it a little bit and used hammer to make it fit, but it's so easy to mess up. You can see that some of the joints were broken.
