Hoffman Engineering

Mechanical Design for Chattanooga Shops and Builders

On-demand mechanical engineering without the overhead of hiring.

What I Do

Sheet metal, weldments, fixtures, prototypes

3D CAD Design

SolidWorks & Fusion 360 modeling from sketch or concept.

Sheet Metal & Weldments

Design-for-fab parts ready for your shop floor.

Fixtures & Tooling

Custom jigs, fixtures, and production aids.

Product Prototyping

From napkin sketch to manufacturable design.

Design Philosophy

Three-Pass Process

Every design goes through three passes before it leaves my desk.

PASS 01

Function

Does it do the job?

Every constraint defined before anything is drawn.

PASS 02

Form

Is it buildable?

Geometry that suits your shop's equipment and stock.

PASS 03

Finesse

Is it right?

Final drawings and documentation, complete enough to build from.

About

The engineer behind the work

I spent 10+ years at Michelin, Daimler, and Astec. Now I work directly with small businesses in Chattanooga. Same standards, smaller jobs.
