If you have ever bought a new Lego Technic set with Pneumatic you realized for sure that the brand-new Pneumatic Switches are often very tight. With such a switch operating really sluggishly sometimes it‘s difficult to operate a mechanism, for example one like the crane on the Mercedes Arocs set. So I invented a “Pneumatic Switch Torturer”. It does one thing only: it toggles the switch again and again and again … The “Torturer” simulates months and years of use to make the switch little bit smoother.
Be careful to build all moving parts free-moving. Use of the machine is on own risk.
