Say hello to The Stubster—your palm-sized, micro-handle sidekick that squeezes into tight spaces where the regular Multi Drive can’t reach. It packs all the same handy features as its full-size sibling—bit-holding, secure grip, quick-swapping—all wrapped into a compact powerhouse.
Helical gears are the best thing since sliced thread
But helical gears are great – to look at and to use. And you’ll find them in a lot of places. So let’s get our butts into gear and explore these smooth criminals of the engineering world.
Every great product starts somewhere—often in a workshop full of wild ideas, exploded prototypes, and the occasional insurance risk! In this behind-the-scenes dive, we look back at the curious contraptions and “what-were-we-thinking” builds that eventually led to the sleek, refined Multi Drive.
How to pick the right model-making tools (for a sanding ovation)
Why step up your tool game?
Your modelling skills will outgrow basic gear pretty fast. A sharp, sturdy setup lets you finesse details, save time, and spare your fingers the agony of crummy kits.
We’re tearing apart the Multi Drive and looking at each piece in excruciating detail.
How aerodynamic bearings became engineering’s smoothest operators
We delve into the fascinating world of air bearings—components that use a thin film of pressurised gas to provide a low-friction interface between surfaces.
The ‘Watch-ima-collet’: The Time-Ticking History of The Collet
From dainty 18th‑century watch benches to roaring factory floors, the collet shows how micro‑innovations can power mega transformations. Tiny sleeve, massive impact—grip tight, friends!
The history of the engine piston (ft. lots of ups and downs…)
We delve into the evolution of the engine piston—a component that plays a pivotal role in converting energy into motion. From its early use in air-pumping systems around 150 BC to its development in steam engines during the 18th century, the piston has undergone significant transformations.
