Hello everyone!
First of all I would like to say that although I am a new user, I have been visiting this forum for some time and some of you may know me from my activity on Rebrickable. This contest has finally motivated me to register here and to make BWE that I have been thinking about for a some time.
Planned dimensions in studs WxHxL 15x20x33=9.900
Planned main functions:
- rotaring bucket synchronized with the belt for excavated material
- gearbox for switching drive from tracks to manual
- rotaring and lifting main arm with bucket
Some photos showing gearbox, bucket idea and current progress:
