I kind of have an amazing hookup with a retired guy that has a big slabber bandsaw and a logger friend and likes to mill wood so I get amazing slabs at ridiculously low prices... today I picked up seven 19" wide black locust slabs and three more 33" wide butternut slabs.
A fellow maker friend helped me put with the legs and we fabricated them locally specifically for the dimensions of this table. If your close to stl we could probably help you out. I would also highly recommend rubio monocoat 2c for hardwood finishing, its amazing stuff.
Yes I made a box joint jig for the table saw and created a first cut template. I got an old 1x42" sander to sand between the teeth and shape the points. I used the ryobi benchtop sander to shape the curves.
I really enjoyed seeing the oak transform from what looked like wood destined for a burn pile to beautiful tabletops. Most of all I enjoyed seeing the excitement and smiles when we delivered them to their new home.
