Our analysis of the professional mechanic's kit in the parc fermé starts from the basic element, i.e. what the kit contains: the toolbox. However, if you are under the impression that, at the highest levels of international karting, they use specific containers that can be purchased in some sort of specialist shop, you’ll have to think again. In fact, Thomas Mardaga's is an everyday box (dimensions 40 x 30 x 17 cm), which can be purchased for about 30 euros from any tool shop. However, what makes the difference is the degree to which the generic container is customised and its obsessive organization, made possible thanks to a system that sub-divides the available space into precise compartments. On the bottom of the box there is an aluminium divider (designed specifically by a colleague of Mardaga’s, Neil Mackerman of the Beyond Racing Team, to meet the needs of professional kart mechanics), which allows the orderly and desired distribution of different types of tools, such as an Allen key kit or screwdriver set. Furthermore, in order to optimise the available space, Thomas has a removable aluminium shelf that he uses mostly for electronic devices (such as the pressure gauge and stopwatch) and an additional plastic box, also equipped with dividers and compartments, which it is used to store small spare parts: these range from generic ones, such as screws and bolts, to more specific ones, such as sprockets. Lastly, to avoid wasting even just a single cubic centimetre of space available, special hooks have been placed on the inside of the lid of the box to house tools such as the spark plug wrench or everyday plastic ties. Therefore, each tool has a precise location, which allows Mardaga not to lose any time whatsoever in searching for the right tool, electronic device or spare part, for any need out on the track. Whatever the frequency with which you drive a kart, the advice of a professional mechanic such as Mardaga is to "organise your toolbox as precisely as possible, since, in addition to ensuring prompt intervention in any situation, it will help you assess both the condition of your tools and when it is necessary to go to your trusted hardware store to stock up on spare parts”.
