Lego Space Station
This was to be the start of a new bigger again big jobs tractor. 15cm diameter and as solid as a rock.. But since uploading I'm thinking possible - microscale space station, traction steam engine, engine exhaust for a SHIP (not serious here), field artillery,?,?, what can/will it be... While I'm waiting for more of those 1x4x2 inverted slopes, I'm open to suggestions from you guys...but the field artillery is really feeling good for me.
