I was asked for a digger this afternoon at a balloon gig I was doing up in London, I got by and made something that was just about passable so tonight came home and made this.
The base is from my tank design and I built up around that, I then decided to add the rear bucket as well.

I updated the digger, I think it was last week.
It was made for the Balloon Challenge over on The Balloon Artistes Guild Facebook Page,
