Neodymium Magnetic Balls (@1013) - Digger Bulldozer ... More build photos: http://www.flickr.com/photos/tend2it/sets/72157631653093780 ... New and improved version can be found here ... http://www.dotpedia.com/creation/view/2657 ... I've always had this design in the back of my head to do. After several attempts, this one came out the closest to what I had in mind. This little beauty has a little scooper blade in the front, wheels instead of caterpillar treads, a digger arm in the rear with two stabilizing legs on either side. It has a solid body using the same layering building technique I've used in the past (start with a parallel center and work your way outward adding details as part of the layering). The wheels were done using a hexagon layer on one side and an offset circular ring pattern on the other. The wheel axle height is compensated within the body using a notch. Because of the single strand magnetic field, the front roof supports could not be straightened out. Hard to see but there is a little seat for the driver inside the cab area, which is open. The weight of the entire thing is resting on the wheels, making it want to bow a little. One improvement would be to add a few magnets below the axle center to give a bit more support hidden between the wheels down to the ground. Uploaded from flickr.com on Sept 29, 2012.
