Modern Tools in a Centuries-Old Pursuit

These are simply modern tools that aid in a centuries-old profession and pursuit. The goal of excellence in violinmaking has not changed—only the tools to achieve it. At the end of the day, this service is a very well-informed apprentice for a profoundly reasonable price.

We do not sell CAD files or computer drawings. CNC milling and 3D modeling are strictly the tooling required to cut clean, repeatable physical parts on our machine table. The service exists to give violinmakers of the highest caliber consistency across models and more time to focus on the fine details. Consistently cut plates open up avenues of choice and offer more ways to appreciate the form and function of a given geometry.

The Workshop Asset · Centuries of Context

Centuries of Context. A Single Point of Contact from Start to Finish.

Our greatest asset is understanding centuries of context and being a single point of contact who takes the process from start to finish.

When you work with Outlier Workshop, you are not handing your tonewood or measurements to an industrial machine shop, a CAD technician, or a disconnected middleman. You work directly with a person who has both built violins by hand and engineered high-level production design and precision fixturing for premier instrument makers worldwide:

Independent Luthiers Individual master violin makers all over the world
Buscarino Guitars World-renowned handcrafted archtop guitars
Bourgeois Guitars Legendary master acoustic lutherie & production engineering
NS Design Ned Steinberger's pioneering electric bowed & upright instruments
Eastman Strings The largest orchestral string instrument manufacturer in the world

Having carved plates with finger planes, graduated spruce, and voiced acoustic instruments at the bench, we understand the wood and the maker’s intent. Having developed high-tolerance fixturing and CNC CAM strategies for global builders, we deliver machine repeatability without compromising hand tradition.

About

Ben Pearce

I'm a luthier and designer in Cambridge, Massachusetts, where I run ViolinArching.com and Outlier Workshop. I'm an architect by training and a lifelong student of drawing, and I've always been drawn to representing organic forms in the abstract. I've spent many years studying violin arching and its documentation, reconciling traditional drawings with modern methods such as CT scans and 3D point clouds. From that work I produce moulds, plates, and templates for violin makers around the world.

I don't believe musical instruments are magical objects. They're the result of disciplined process, careful material selection, and geometry. That outlook has made me a resource for dozens of independent violin makers internationally, and for builders at every scale, from Bourgeois Guitars to Eastman Strings, one of the world's largest instrument manufacturers.

After studying at the Rhode Island School of Design, I spent six years apprenticed to violin maker Karl Dennis, learning the methods of the classical Italian makers. Today I adapt industrial tools to the workbench without losing the character of handwork.

I'm an active mandolinist and teacher. Away from the bench, you'll find me fabricating staircase parts and custom millwork, or playing with my daughter, Meryl.
