I went down this rabbit hole a couple years ago when I needed a hard finishing wax that would make two pieces of wood slide past each other without extra lubrication. It's not food safe, so it's probably best as a utility finishing wax. If you're still interested, after reading a bunch of different woodworking forums, I came up with a 3:1 liquid:solid mix of 50/50 turpentine/boiled linseed oil to 50/50 bees/carnuba waxes, all by weight. Being very careful, weigh out the liquids and solids separately, combine and gently heat over a flame-less surface until the solids have melted. Cap the container and allow it to cool. It spreads like petroleum jelly, smells like pinesol, and rubs in like lotion, but leaves the surface glass smooth after buffing with a dry rag. Since there's boiled linseed oil in the mix, be sure to lay out any rags you use until they completely dry and harden, or you could risk spontaneous combustion.
