Take a look at the front drive wheel in the following photo:

and you'll see a basic "flange" that connects a wheel to an axle at a 
right angle.  This homemade flange was built by brazing a 1/2" nut to a 
1/2" fender washer, drilling three holes through the washer and two 
holes through the nut.  Three screws/bolts hold the washer on the drive 
wheel and a pin holds the nut on the axle.  You can purchase flanges of 
virtually any size from places like McMaster Carr, but that takes the 
fun out of brazing or welding something :-)  My approach assumes that 
you are turning the axle.

The photo you included was of the Cromwell's drive wheel, which uses a 
different approach ... the axle is stationary and the wheel rotates 
around the axle.

In that approach, the drive sprocket is mounted on the inside of the 
drive wheel with three 1/4" bolts and there are two bearings inside the 
drive wheels, allowing it and the attached sprocket to rotate around the 
shaft.

Hope that helps.
