Johan Kars is quite an interesting fellow. An inventor of a Catalytic Abatement System for Organic Solvent Emissions (yeah, we had to Google that, too), Johan is also an accomplished pilot and an overall helpful guy: having reengineered and improved upon the waffle irons for his friend’s breakfast restaurant.
And it’s only natural, with a name like “Kars”, that he’d become a collector of classic automobiles.
Acquiring a 1951 Bentley, (the MKVI H.J. Mulliner Lightweight ‘Saloon Coupe’, to be exact), Johan sought to restore the bumper of the vehicle, which had been damaged in 1969 during a bad parking attempt. Only 7 of these vehicles were made, so bumpers for this car are not all that easy to come by.
Enter Exact Metrology. With our non-contact scanners able to capture precise data about the existing bumper and rear-end of the vehicle, the Bentley’s bumper can be remanufactured, using our data, to be just as it was in 1951.
For you car enthusiasts, the story of this vehicle is a good one: In 1951, H.J. Mulliner produced only 7 MKVI H.J. Mulliner Lightweight ‘Saloon Coupes’.
The car was originally exhibited on the H.J. Mulliner stand at the Earl’s Court Motor Show in October 1951. Being a ‘MD’ series, it is one of the first of the 4½ liter versions of the car, which were introduced that year. The coachwork is a rare 2-door aluminum body with a hood that stretched an extra 3 inches, an enhancement to the classic, flowing lines.
These Bentleys were in high demand and went all over the world. The original owners of the 7 cars included: H.R.H. Princess Faiza of Egypt, Baron Jules de Koenigswarter of Mexico, Antenor Patino of France and Henry Ford II of the US.
The vehicle Johan Kars currently owns was commissioned by Magnus S. Swenson, who resided on Wall Street in New York, and was delivered to Magnus in November of ’51. In 1953, the car was sold to Martin Block, a famous radio host, living in New Jersey, who passed away in 1967. The car was then driven on occasion by Mr. Block’s mistress, until her son locked the car in a garage in 1969 following a bad parking attempt. A rudimentary repair was done to the rear fenders, but some damage remained.
The car has sat garaged since then… until recently.
Seeking to restore his precious purchase, Johan contacted Exact Metrology to begin the process of reconstructing the car’s bumper. And Exact was well-prepared and eager to help.
Arriving on-site with our portable NDI Scan System, complete with the handheld laser scanner was ideal for fast, non-contact digitization of physical components. The scanning technician was able to quickly and accurately collect 3D data about the Bentley’s rear end and existing fenders.
The NDI Scan System is a productive, field-proven tool. Its technicians were able to orient the ScanTRAK in all six degrees of freedom (6DOF) without concerns that the beam will break and with no mechanical restrictions. The system has a large measurement volume that eliminates the need for time-consuming data capture,
Once the data was collected, we returned to our facility to complete the modeling. Using Geomagic Studio 3D Reverse Engineering Software, which converts 3D scan data into CAD models, Exact was able to create the following 3D model of the Bentley’s fender:
This data can now be utilized to reverse engineer the bumper, creating an exact replica of a part that hasn’t been made since 1951. And Exact Metrology, successfully, has assisted Johan to bring his Bentley back to life.
