Don't get me wront. It's a nice built, but proportions are not correct. The distance of the caterpillar and its width is not correct. The drill would be better designed as a solid one.
You said this could be built with only the 42055 set. I got through about 70% of it before I ran into an issue. you used 3 24-tooth gears in the system, 1 on each tread and 1 on the spool for the string. but the set only comes with 2
Really amazing! And it works beautifully ... I signed up to see other great ideas, congratulations! I'd like to build it, are there any instructions? Thanks Davvero fantastico! E funziona a meraviglia... Mi sono iscritto per vedere altre grandi idee, complimenti! Mi piacerebbe costruirlo, ci sono le istruzioni? Grazje
I work with these machines everyday. The detail in this replica is incredibly well done. There is much room for improvement however. Hopefully lego technic will dedicate themselves to building a drill rig set on its own.
