Art, Science… and Moon Globes!
A high definition raised relief topographic master is machined in aluminium (cutting at 64 microns the width of a human hair). The process is controlled by topographic data supplied by NASA’s Lunar Reconnaissance Orbiter.
The use of computer controlled machining to create the aluminium Master allows for greater precision and better surface finish compared alternative production methods
Several layers of metal powder and resin are slowly built up in a mould taken from the topographic master (a process known as cold casting).
Each layer is given 24hrs to fully cure before the next layer is added.
The cold casting process accurately recreates the fine detail of the original machined aluminium globe master.
Once taken from the master mould, globes are finished by hand. This includes,
♦ Creating the surface tone and finish.
♦ Adding the brass dividing ring.
♦ Inscribing 30 degree meridian lines.
♦ Adding text and feature names.
♦ Applying final protective coatings.
Each globe also comes with a solid aluminium stand.
This is designed to complement the overall aesthetic of the globe and give it its distinctive retro futuristic look.
The stand is made of polished Aluminium and consists of the following parts…
♦ Five discs and spacers.
♦ Three machined arms.
♦ A central boss with machined slots.
♦ Top and bottom caps
The globe sits securely on the stand, and can be lifted off or repositioned as required.
20cm Moon
♦ Weight = just over 1Kg.
♦ Height = approx 27.5cm
30cm Moon
♦ Weight = around 2.2 Kg.
♦ Height = approx 39.5cm
Due to the time it takes to make each globe, the numbers produced will always be low.
This is why each globe has an etched brass plate showing its unique production number and year of manufacture.
The brass Terrainian Space Globe nameplate assembly slots into the gaps between the aluminium discs of the stand and can be removed or repositioned as required.
This identifying info is also on the globe itself , and on the underside of the stand
