Just recently I discovered the magnificent LEGO Technic building sets. What a beautiful designs they have made!
I started out with their “crawler crane”, a crane on threads. After that, I did the bucket wheel excavator, the largest set at this time. And third, I built the Mercedes truck. Pictures of all three can be found below.
They were great fun to build and what’s more, a great source of parts for building my own contraptions… ?
