Project Overview & Client Objective
As a contracted Mechanical Engineer for Red’s Best, a seafood supplier in Boston, MA, I was responsible for designing and building a custom fish processing conveyor system. The project ran from October 2023 to June 2024, with the goal of creating a durable, food-safe, and space-efficient system to improve workflow. The objective was to deliver a fully functional conveyor system within a 9-month timeframe, meeting both client requirements and practical fabrication constraints.

I. Design and Development Process
The project encompassed the full lifecycle of mechanical system development, from initial design through on-site installation.
System Design in SolidWorks:
The conveyor system was modeled from the ground up in SolidWorks, including:
- Conceptualizing a multi-tier layout to optimize space and workflow.
- Creating an initial CAD proposal for client approval before detailing further.
- Modeling custom components such as frames, supports, and chutes, alongside purchased items like motors, gearboxes, and belts.
- Building assembly models to check fit, form, and function.
- Producing fabrication drawings to guide the build.

Design Modifications & Iteration:
The design went through several iterations to incorporate client feedback, account for available materials, and simplify fabrication. This process refined the layout and ensured the final design balanced functionality with manufacturability.
Material Procurement & Management:
I helped manage procurement of all necessary materials and components, including:
- Stainless steel for structural and food-contact parts, chosen for durability and compliance with food processing standards.
- Modular conveyor belting, motors, and gearboxes sized for the application.
- Coordination with suppliers to ensure timely delivery and stay on schedule.
II. Fabrication, Assembly, and Installation
The project required both design engineering and hands-on fabrication.
Fabrication:
- Structural elements were cut, welded, and machined from stainless steel.
- Practical tolerances were considered, with oversized bolt holes and adjustment slots incorporated to accommodate variation from hand and shop-tool fabrication.
Assembly:
- The system was assembled by combining fabricated parts with purchased components.
- Alignment of conveyors and roller spacing were verified to ensure smooth operation and durability.

On-Site Installation and Client Collaboration:
- Once assembled, the conveyor system was transported to the Red’s Best facility.
- I coordinated the on-site installation, working closely with the client to position and integrate the system into their processing area.
- Final checks were performed to confirm full functionality and meet operational requirements.
