This is a 5 axis cnc router I designed and built as a personal project. The linear stages were found by a friend of a friend dumpster diving, back when I was in school.   I welded the frame together from off cuts found at the local metal supply house.   The electronics cabinet was also as salvaged enclosure.

This was a quick two day project to make an automated circuit board programmer for the Rondo project.

Rondo Motion

Category: Product Design

This is a housing and attachment mechanism, I designed and engineered, for Dysonics Rondo Motion Application.    The "Head Tracker"  is a bluetooth 3-axis accelerometer and a 3-axis gyro that tracks the heads movement.  The housing was designed to be able to mount to any over the ear type of headphones.

Circular Bench

Category: Craft

For this project I adapted the architects drawings for fabrication via our CNC router.   Then in collaboration with Larry Hitchcock of Intrepid Marine we fabricated the bench and assembled on site in a Sonoma winery. This project was a bridge project for me, bridging my first carrier as carpenter craftsman with the digital craftsmanship learned in design school.

Bounce Guitar Stand

Category: Craft

This was my own project I came up with, while working with Blackbird Guitars.   In a need for a bunch of guitar stands for NAMM.  Somehow I came up with the idea that I needed to use  racketballs as padding for the guitar.   While I wouldn't advise it to others,  I thermoformed the acrylic myself in my oven at home.

Adapted traditional guitar making techniques for the making of carbon fiber guitars.   Alas I am no longer involved with them, but they are still creating an excellent product here in San Francisco, check out their poduct here:

About Troy

Interdisciplinary Design Engineer New World Craftsman.

In my first career I worked as a finish carpenter for 13 years  in the high end home building market of the San Francisco peninsula.   At age 30 after taking some evening classes in Autocad I decided to go back to school and get a degree in Product Design from San Francisco States, Design and Industry program.   It was there that I discovered a passion for 3d cad design and CNC manufacturing.

Since graduating in 2003 I have worked on numerous design projects, including projects for the design consultancy Think2Build.  I also partnered up with a friend from San Francisco State Joe Luttwak and helped to found BlackbirdGuitars.  I stopped working with Blackbird several years back but they are still going strong building carbon fiber guitars here in San Francisco.

Currently I am working for myself as a Design Engineering consultant and working to launch my own product line of Wooden Eyewear, along with the occasional fabrication job that comes along.

For the last 10 years or so I have  maintain a shared studio space with an ever changing diverse group of friends.  Currently that includes  neuroscientists, and a custom furniture maker, amongst others .   We have 2000 sq.ft of shop space, that includes a full wood shop, 4×8 cnc router with a 4th axis,  a bridgeport knee mill that I converted to CNC myself.  We also have 2000 sq ft of individual office space.
