Twiddling Knobs

We like a good knob twiddle* here at The Lego Car Blog. Get your minds out of the gutter – we’re talking hand-powered mechanical functions.

This is one such creation imbued with knob twiddling goodness, and it comes from previous bloggee M_Longer, who has repurposed the pieces found within the LEGO Technic 42121 Heavy Duty Excavator set to create it.

Loosely based on a JCB skid-steer loader, M_Longer’s 42121 alternate utilises a pair of knobs to mechanically control the arm and attachment tilt, so you’ll need to play with the knobs a bit before you can get forking. Ask your Mom.

There’s more of M-Longer’s B-Model to see at the Eurobricks discussion forum, where links to both further images and to building instructions can also be found. Twiddle your knob via the link above!

*Except in this case. As it’s ridiculous.
