Reverse Engineering & Machining: 1916 Buick Shaft & Bronze Bush Replacement

The Problem

A customer needed a replacement shaft and bronze bush fitted as part of the restoration of a 1916 Buick.

Unfortunately this job had been delayed for some time, moving between workshops without being completed. The part was originally brought in while the previous owner Bruce, but due to illness it was never finished and returned.

For this stage of the restoration to continue, the shaft and bronze bush needed to be made, fitted, and paired accurately so the distributor input shaft could connect properly with the water pump assembly.

The Engineering Solution

Pinney Engineering Services reverse engineered and machined a new shaft and bronze bush to suit the original vintage vehicle assembly.

The parts were made more robust and fit for purpose, then fitted together with new bolts to ensure correct alignment and operation.

This type of work requires more than simply copying a worn part. Older vehicle components often need careful fitting, practical machining knowledge, and small improvements where appropriate so the finished assembly works reliably in the real machine.

The Reverse Engineering & Machining Result

The new shaft and bronze bush were machined, fitted, and completed so the customer could move forward with the next stage of the 1916 Buick restoration.

This was also a meaningful job for the business, as it was originally connected to work brought in under the previous owner Bruce before his illness and passing. It has now been completed by the new owners, John and Janine, helping close the loop for the customer and keep the restoration moving.
