01 · WHAT WE MAKE

Built for the work that can’t fail.

PROTOTYPES

Geometry that doesn't exist yet, machined to a real, held part. Single-setup precision, verified before it ships.

FIRST ARTICLES

From drawing to a proven, measured first article — nothing left to luck. Process-verified, capability-confirmed.

ONE-OFFS

The single part others decline — turbine, off-road racing, R&D. Rare geometry. Real stress. Tolerance that holds.

CUSTOM ASSEMBLIES

Machined components integrated with precision welding, fabrication, and finishing. Complete functional systems, not just parts.

02 · PART FAMILIES

Parts like these, machined and inspected.

Shown by type, never by client.

A machined aluminum housing on a T-slot table, backlit: a stepped central bore, a pocketed front face around a raised boss, a second bored face at ninety degrees, curled chips beside it. — MACHINED HOUSING
Cut from solid, bored on two faces at ninety degrees

A machined bladed turbine wheel mounted on a plate. — TURBINE WHEEL
Turned hub, five-axis blades

Three contoured aluminum panels on a dark bench: the largest pocketed, ribbed and drilled, the two smaller ones curved, each drilled to its own pattern, a scriber and dividers beside them. — AEROSTRUCTURE PANELS
Contoured, pocketed, drilled to pattern

A relief-milled aluminum engine cover standing on an oil-darkened shop bench, its lettering and pocket walls cut proud of the face, radiused edges and three bossed mounting tabs, a micrometer resting beside it. — MOTORSPORT ONE-OFF
Relief lettering milled from solid, three mounting tabs

A compressor wheel seen low-angle on black. — COMPRESSOR
Five-axis blade flanks, as machined

A machined aluminum bracket at an aircraft structure in the hangar. — AEROSPACE
Bushed at both eyes, the web pocketed through

The same machined bracket shown twice under one light: at left as it came off the machine with cutter witness across the faces, at right after vapor blasting, the same edges and the same bores now carrying an even satin. — AS MACHINED → BLASTED
Same bores, same edges — only the surface changed

A machined aluminum housing shown twice under one light: at left straight off the machine, the cut faces still bright and carrying tool witness; at right after vapor blasting, every face and radius now an even matte. — AS MACHINED → BLASTED
Cut faces bright off the machine, then an even matte

These are the kinds of parts we can show.

Development hardware and pre-release parts are most of what runs here. That work belongs to the people who designed it, which is why it is not on this page and why no client is named anywhere on this site.

03 · THE NEXT PART

The first one is cut so the second one doesn’t start over.

Development work is rarely made once. The print changes after the first article, and the shop is set up for the part that comes after it.

PART ONE

The first time the geometry has been cut. It is fixtured and programmed knowing part two is coming, so the fixture and the program are built to run again rather than thrown away with the first part.

PART TWO, PART THREE

The print changed. That is not starting over here — it is the next part of the same one: the setup carries over where the print lets it, and the edits are programmed in. Send the part that failed with the new print; the failure carries information the drawing does not.

THE PROVEN PART

When a part is proven and a short run of it is wanted, it is held the same way — the fixture matters more than the cut, and that is what keeps the last one the same as the first.

Send the part that scares them.

A print, a model, or the part itself — even one that has already failed. Send whichever you have, and feasibility comes back as a real path.
