Every board starts the same way: a slab of hardwood clamped to a spoil board, and a Shapeoko 5 Pro cutting hex pockets one pass at a time. The machine doesn't make the board special. What it makes possible is the part that does — pockets tight enough that a resin tile drops in flush, every time, across sixty-one hexes.
The Machine: Shapeoko 5 Pro
We run a Shapeoko 5 Pro, a rigid-frame CNC router built for exactly this kind of repetitive, precision-dependent work. It's overbuilt for hobby projects and undersized for a production furniture shop — which puts it right in the sweet spot for a father-and-son operation cutting inlay pockets in batches of hardwood.
The frame rigidity matters more than the spindle speed. Hex pockets are shallow — a few millimeters deep — but they have to be dimensionally identical from the first board of the day to the fiftieth. Any flex in the gantry shows up as a pocket that's a hair off center, and a hair is enough for a tile to sit proud on one edge.
Why CNC Instead of Hand-Carving
We get this question a lot, usually from people who assume "CNC-cut" means less craftsmanship than a hand-carved board. It's the opposite. Hand-carving sixty-one hex pockets into a single board, each one needing to match its neighbors within a fraction of a millimeter, isn't a repeatable process — it's a lottery. Grain direction changes how a chisel bites. Fatigue changes how steady a hand is on hex forty versus hex five.
The patent-pending inlay design depends on that repeatability. Each hex pocket has to hold its tile at a consistent depth and a consistent fit, board after board, species after species — walnut, maple, cherry, white oak, pecan, Osage orange, all of which cut differently. A CNC program doesn't get tired and doesn't care that Osage orange is denser than maple. It runs the same toolpath at the same feed rate and the same depth, every time. That consistency is what lets us sell a design as a product line instead of one-off art pieces.
Tolerances That Actually Matter
We hold pocket depth to within a few thousandths of an inch — tight enough that a tile seats flush without a visible seam, loose enough that seasonal wood movement doesn't crack the pocket wall. That's the real engineering problem: wood expands and contracts with humidity, and a pocket cut too tight in a dry Tulsa winter can bind in a humid summer.
We dial in feeds, speeds, and stepover for each species rather than running one universal program. Denser woods like Osage orange get slower feed rates and lighter cuts per pass to avoid tear-out at the pocket edges; softer species like maple can run faster without losing edge quality. It's less "set it and forget it" than people assume — the machine gives us consistency, but getting the program right for six different hardwoods took real trial and error. Our hardwood species guide covers how each wood behaves once it's off the machine and into finishing.
Bit selection matters as much as feed rate. We run small-diameter upcut end mills for the hex pocket walls to keep the corners crisp — a hex has six of them, and a rounded-over corner is the fastest way to make a tile sit proud. Toolpath order matters too: we rough each pocket first, then run a finishing pass around the perimeter last, so the walls come out clean instead of showing stepped tool marks from the roughing pass.
The Hand-Check Step
The machine finishes its job and the human part starts. Every board comes off the Shapeoko and goes through a hand inspection before it moves to finishing. We check every hex pocket by hand, seating a test tile in each one, feeling for anything that's not flush — a pocket that's a touch shallow, an edge with slight tear-out, a corner that didn't clear on the final pass.
This is the step that separates CNC-cut-and-hand-finished from CNC-cut-and-shipped. A machine that runs the same program on the same wood can still turn out one board with a stubborn grain pocket that needs a pass with a chisel and sandpaper. We catch that before the board ever gets Odie's Oil, not after a customer opens the box.
Once every pocket passes inspection, the board gets sanded through our finishing grits and finished with Odie's Oil — a food-safe hardwax that soaks into the wood rather than sitting on top of it, so the same hand-check process that verified the geometry also sets up the finish to look right.
What This Means for the Board You Get
The CNC is why a Heirloom Inlay 2-4 Player board plays the same whether it's the first one we cut this month or the fiftieth. It's also why The Heir, our double-sided board, can hold two full hex layouts on opposite faces without either side compromising on fit — both faces get cut to the same tolerance, on the same machine, in the same setup. The same programs scale up to our 5-6 player expansion layout, which needs more hex pockets cut to the exact same spec across a larger panel.
None of this replaces the woodworking. It's the opposite: the CNC handles the part that has to be identical every time, so we can spend the time that matters — grain selection, hand-fitting, finishing — on the part that makes each board actually worth keeping. If you've got a project in mind that doesn't fit our standard sizes, that's what our commissions process is for.
The Short Version
A Shapeoko 5 Pro cuts every hex pocket to a tolerance a hand tool can't hold across sixty-one repetitions. That precision is what makes the patent-pending inlay design work as a product instead of a one-off. Then a person checks every pocket by hand before the board ever gets finished. The machine gets the geometry right. The hands make sure it plays right.
