Something I'n working on now. First a photo of the original.
As base I'm using the reissued Mack DM800 by King models.
The wheels were designed by me and 3D printed at Shapeways.
The chassis is ready for paint. The front axle was shortened and fixed a little forward to make the bigger front wheels fit.
The engine is the good old V8 Mack.
there is more to come.
