For Lin, a dedicated lifelong learner with a focus on precision instruments, the M-73 prismatic compass was the cornerstone of his educational project. His goal was to provide the public with detailed information about this military-grade magnetic instrument, covering its history, operation, maintenance, and repair. To support his research, Lin designed a custom mount that would stabilize the compass during testing, alignment, and surveying.
The challenge lay in finding a manufacturing partner capable of producing the custom mount to Lin’s exact specifications. He required a solution using non-magnetic materials and precise tolerances. After reviewing several potential suppliers, Lin selected Lewei Precision for its ability to meet his technical requirements while delivering the components on time and within budget.
The custom mount needed to be adapted to existing equipment that was not originally designed for this purpose, while ensuring maximum stability and precision under outdoor and suboptimal conditions. In addition, the material had to be non-magnetic to prevent any interference with the compass needle.
“I needed a partner who could produce a CNC-machined part that met very specific requirements for material and precision,” Lin said. “Lewei Precision was the only supplier able to deliver what I needed on time and within budget.
Lewei Precision’s engineering team carefully reviewed Lin’s design and worked with him to optimize it for CNC machining. The solution included:
Lewei Precision’s commitment to high-quality engineering and customer satisfaction extended beyond the manufacturing process. By providing detailed assessments of the part’s machinability and suggesting design adjustments, Lewei ensured the project’s success from start to finish
“I was impressed with how quickly Lewei Precision moved on my project,” says Lin. “Their team was highly responsive and provided valuable feedback that helped refine the design
Lin successfully tested the precision mount, and it passed field tests with flying colors. The mount’s high accuracy and durable materials allowed Lin to complete his research swiftly, without exceeding his budget. The project’s success has led to ongoing collaboration between Lin and Lewei Precision.
“The mount’s performance in testing was outstanding, and now they’re being used on challenging terrain at Singapore’s Bukit Timah Nature Reserve,” Lin shares. “Lewei Precision’s parts continue to support my research and development efforts.”
My specially designed tripod land survey mounting blocks for the M-73 prismatic compass are being deployed in treacherous terrain on Singapore’s highest mountain (16,300 cm) in National Parks Board’s Bukit Timah Nature Reserve. Each high-strength block of solid material weighs 1 kg and was precision-machined by Lewei Precision Co., Ltd who have also supplied high-quality experimental “missile parts” for my hyperphoton launch system announced earlier.
Building on the success of this project, Lin plans to create a second-generation version of the mount with improved centering precision and clamping stability. Additionally, Lin is considering the design of a dedicated adapter for compass needle calibration. He intends to continue his collaboration with Lewei Precision, confident that their expertise and reliability will continue to support his work.
“I’m excited about what the future holds, and with Lewei Precision as a trusted partner, I know I can keep refining and expanding my educational work,” Lin concludes.
