Jonathan Rooney (Fabrication Assistant at Bray) created this puppet for the Department of Drama and Dance’s winter show – The King Stag.
At Bray, we use a slotted spoil board with our CNC Router. This enables us to attach clamps to a t-slotted table below:
One of the legs in the foam jig
In the past, we have used the Rockler Hold Down Clamps to secure material. However, this clamp can damage our router bits due to collisions with the clamps:
We 3D printed clamps to mitigate this issue. The PLA and ABS plastic clamps prevented damage to the bits from collision:
However,the plastic clamps cracked under the clamping forces:
The clamps were then printed with a combination of nylon and carbon fiber on a Markforged Mark Two 3D Printer:
These clamps were much stronger and able to flex without cracking. The clamps were tested on the mill to simulate a bit collision. The milled carbon fiber broke into fairly large chips. There was a concern that the carbon fiber and nylon material might melt onto the bit. However, the bit came out clean. Check out the video clip below:

Mechanical Engineering students designed an injection molding machine for a senior design course.
Wentworth Institute of Technology
The Bray Lab staff and summer interns visited the Center for Applied Research at Wentworth Institute of Technology in their Department of Architecture. The Center supports bachelors (sophomore year and above) and masters students in Architecture – around 450 students.

Finally, we wrapped up our field trip with a visit to the Museum of Fine Art which offers free admission for Tufts students.

This week the Bray Lab staff and summer interns visited Artisan’s Asylum, a non-profit community fabrication center in a 40,000 square foot warehouse located in Somerville.
We got a chance to checkout the setup of their equipment stations:
Artisan’s Asylum – Soldering Station
Artisan’s Asylum – Jewelry Station
Artisan’s Asylum – Casting Room
as well as their storage methods:
Artisan’s Asylum – Vertical Storage
We met the Overhaul robot featured in BattleBots and spoke with one of its makers.
Artisan’s Asylum – Overhaul BattleBot
We checked out some of the builds to gain inspiration for projects in Bray.

Chandler Coble (Mechanical Engineering ’17, Shop Assistant) and Anu Gamage (Electrical Engineering ’18, Summer Scholar) working on creating an inverted pendulum.
For more information, check out the Inverted Pendulum Summer Internship blog post.
Jason Linker and his Tufts Robotics Club team have created a fire-fighting robot. The robot traverses a maze and detects and extinguishes flames.
Whitney Crooks, Gabrielle Vukasin and Maeve O’Sullivan used the Design Lab’s 3D printers to create molds for making flexible robotic hands. Learn more about their project and fabrication process on their Tufts TIHRA: Tele-Operable In-Home Robotic Assistant blog.
