Every year, Armortek, run by husband-and-wife<br />

team Mark and Gill Watkins, makes around 250<br />

self-assembly kits of model tanks and other<br />

armoured vehicles. <strong>The</strong> company was founded<br />

in 2001 as part of a group of manufacturing ventures, and<br />

originally based in Daventry in the Midlands. In 2006, the<br />

couple acquired sole ownership of the Armortek business,<br />

and relocated the growing operation to the rolling hills of<br />

the South West.<br />

In addition to the impressive Tiger, Armortek also makes<br />

Sherman and Panther tank kits, a scale Sd.Kfz 7 half-track<br />

vehicle and a 88 mm Flak 36 gun. <strong>The</strong>ir latest kit is the<br />

German Panzer III medium tank.<br />

Across the range, the kits vary from low-end models for<br />

static display to top-of-the-range products with built-in motors<br />

and remote control systems. “Some of our customers prefer not<br />

to drive their models, but spend hundreds of hours recreating<br />

dioramas of actual events from the Second World War,” says<br />

Mark. “<strong>The</strong> attention to detail is stunning.” Those clients who<br />

want to “drive” the machines can choose to supplement them<br />

with sound systems, smoke generators and gun barrels that use<br />

12 gauge shotgun cartridges to simulate the effects of real tank<br />

cannon firing.<br />

Armortek’s customers are, typically, military modelmaking<br />

enthusiasts from around the world. In fact, 50<br />

percent of the company’s output is exported, mainly to the<br />

United States. “Some of them have a standing order for<br />

pretty much everything we build,” says Mark.<br />

To grow its business in the USA, the company is<br />

currently on the lookout for a local manufacturing partner:<br />

“Perhaps another <strong>Haas</strong> user with the capacity to help us<br />

better serve our growing U.S. customer base,” Mark suggests.<br />

Irrespective of the way the models will be used, all of<br />

Armortek’s customers demand not just accuracy in the details<br />

and proportions of the models, but also – especially when<br />

they are used in harsh outdoor conditions – appropriate<br />

robustness. <strong>The</strong> build quality and price of the models reflect<br />

their fidelity to the military specifications of their real-life<br />

counterparts; a fully equipped model Tiger, for example,<br />

weighs 160 kilograms and costs in the region of £5,000!<br />

To achieve the consistent manufacturing standards one<br />

would expect for what some might consider a very expensive<br />

toy has meant investing in reliable, high-productivity CNC<br />

machine tools from U.S. machine tool supplier <strong>Haas</strong><br />

<strong>Automation</strong>. Mark Watkins, who personally does all the<br />

machining work, currently operates three <strong>Haas</strong> machines:<br />

a VF-1 and a VF-3 machining centre, and a TL-15 dual-spindle<br />

lathe with a Servo Bar 300 bar feeder. <strong>The</strong> VF-1 was purchased<br />

in 2005, and the other two machines in 2006, when the<br />

company relocated.<br />

Mark says that he works in batches of a 100 kits at a time,<br />

with each batch taking 3 to 4 months to complete. He makes<br />

about 2 1/ 2 batches over a period of 9 months, or so. <strong>The</strong> other<br />

3 months of the year are mostly taken up with research for the<br />

development of new models, which involves seeking out<br />

examples of real machines in museums, photographing and<br />

measuring them, and evaluating their potential as additions to<br />

the Armortek range. <strong>The</strong>re are, Mark explains, few if any<br />

relevant paper drawings still in existence for most of the models<br />

the company produces.<br />
