About
An owner-operated shop in Eaton, Ohio
Cornerstone Manufacturing has machined custom parts and metalwork in Eaton, Ohio since 1989. It is owner operated, with one point of contact rather than an account-manager layer, custom and short-run work is welcome, and design happens in house in SolidWorks. That is what is verifiable about this shop, and it is what this page is built around.
The shop floor
The kind of work that comes through
Four parts, four different reasons a job like each one lands here: a flange machined complete on a turn-mill cell, a shaft turned to a bearing fit, a manifold block milled from solid billet, and a bracket that replaces a broken one. Switch between them.
Custom and short-run work is not a side line. It is the work bigger shops will not take, done right, with one person to call about it from quote to delivery.

A shop timeline
The one dated fact this site can stand behind is 1989. Rather than invent milestones in between, here is what has stayed the same at this shop against what has changed across machining as an industry over that stretch.
This side is Cornerstone-specific.
- Owner operated, in Eaton, Ohio. Same shop, same town, since 1989.
- One point of contact. The person who quotes a job is the person who can answer for it.
- Custom and short-run work welcome. Not turned away for being small.
- A part quoted from a real drawing. Reviewed by the people who will machine it, not a sales layer.
This side is general history of CNC machining as an industry, not a record of Cornerstone's own history, which is not documented on this site.
- CNC controls replaced manual leadscrews and hand-cranked dials as the standard way to hold a dimension.
- Solid modeling, like the SolidWorks this shop designs in today, replaced the drafting board as the way a part gets designed and programmed.
- Tighter tolerances that once needed a toolroom grinder are now routinely held on a mill or a lathe.
- Digital file formats like STEP and DXF replaced paper prints and vellum as the way a drawing moves between a customer and a shop.

About this website
This site is a demonstration build prepared to show what an interactive Cornerstone website could do. The parts shown in 3D throughout are representative geometry created for the demonstration, not Cornerstone customer drawings. Anything marked Illustrative is exactly that: a relative or typical figure, not a quote. A real number for your part comes from your drawing, at quote.
