Bracket Engineering

Jim Bredt is a retired inventor and machine designer who worked for 30 years in the 3D printing industry. He has been active at Artisans Asylum for 10 years and used the shops at AA to develop hardware for one of his 3DP startup companies. In addition to mechanical design and fabrication, he also teaches a weekly figure drawing class.

This class will be especially valuable for new shop users who wish to integrate the available CAD tools in the Design Shop with the fabrication tools in the Metal Shop. Rather than teaching the use of individual tools, this class will teach a production path using CAD design and multiple tools in sequence. We will be introducing Solidworks on a basic level and advancing to the sheet-metal design tools and data processing for the Metal Shop CNC.

Each class has a unique set of projects. We fabricate useful components for various shops around the facility. Students are encouraged to bring their own projects too.
This class will have three 3-hour sessions, generally following this sequence:
1. Mechanics: Introduction to mechanical design; overview of the Metal Shop; lessons on the tools; start work on a class project.
2. CAD: Introduction to computer-aided design (using AA’s installations of Solidworks 2024) and training on the utility software for the CNC plasma cutter.
3. Training: Training in CNC plasma cutting, bending, welding, and powder coating. Finish the class project if time allows.

Solidworks will be taught in the Design Shop in the Holton building. Besides design, tasks such as bitmap-to-vector conversion and merging data from different sources will also be addressed. Tools for cutting, bending, and welding sheet metal are in the Antwerp building Metal Shop. The direct path from Solidworks-generated DXF data through the CNC plasma cutter will fan out to some subset of the following: Hydraulic shear; drill press; jump shear; finger brake; hydraulic benders; torches and welders; finishing with sand-blasting and powder-coating. These tools will be demonstrated to the students in the first session, and training given in the third session.

The materials fee for this class is $30. This is separate from the ticket price and is to reimburse the instructor for any tools or materials used in this class. This will be paid once, directly to the instructor at the start of the first class meeting. This instructor accepts payments in cash or through Venmo.
