Here is a series of photos of a rack I'm in the process of constructing. It's a large fixed front rack, meaning it's brazed to the head tube of the bike. This allows for more weight to be carried up front, and that the bike will still be stable a sure. It's the same principle as is with the Cycle Truck.
I hope you enjoy seeing the process of how racks like this come together. It's quite a job figuring it all out.
