The default American hardwood. Hard, heavy, takes a stain evenly, water-tight enough to make whiskey barrels and wooden boats. The wood Mission furniture is built from. Open enough grain to feel like wood under the hand; closed enough to seal cleanly.
Ring-porous hardwood with tyloses occluding the early-wood vessels (the reason it can hold liquid). Janka hardness ~1360 lbf. Air-dries with moderate movement; quartersawn pieces show medullary ray figure. Joins by glue, screw, mortise-and-tenon. Works well under hand and power tool.
The oak that is good is the oak that does not insist on its own grain. It receives the hand of the carpenter without protest, accepts the shape that the use of the object requires, and gives back what was always inside it. The beauty of a finished piece of oak is the beauty of a thing that did not need to be flattered into being itself.
Wood draws little heat out of the human body when touched, and so is experienced as pleasant, sensual and warm.
It is not this or that tangible steel or brass machine which we want to get rid of, but the great intangible machine of commercial tyranny which oppresses the lives of all of us.

Climb-mill on the ShopBot for clean grain edges; conventional-mill on the MR-1 if rigidity is marginal. The vee tool cuts engraved typography cleanly; use the swarf 'outline' op with vee for raised lettering. Hard against quartersawn grain — feed pressure varies; let the machine pull, don't push.

Oak, carved and originally painted, with marquetry panels; 326cm wide. Shakespeare referenced it in Twelfth Night, first performed 1601.

Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, with cost-over-volume curves, trade-off profiles, equipment-tier filters, and second-life paths layered onto the data so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
