Simon S. Allen suggests the following method of track construction.
I propose that the two lengths of brass rod are used for the track. They are held an equal distance apart. The problem is to devise a method of holding the brass rods apart without impeding the passage of the ball. I suggest that a piece of copper tube is used. Dimensions of 1/8 inch brass rod, 1/2 inch balls with 7/8 inch copper tube work well together. It is very easy to solder brass to copper. Once all the materials have been cleaned (and polished if you wish), cut from the 3/4 inch tube a piece 1/4 to 3/8 inch long. Using some wet and dry on a glass plate clean the end of the piece to give smooth edges. The inside to the copper tube must also be clean as this will be where the solder goes. Next slide the ring over the two pieces of brass rod. You will need a jig to hold the rod the required distance apart. Apply a little solder underneath. You now have the track firmly held. Repeat the process for other links.
The addition of the copper tube also makes it easy to support the tracking by securing the copper tubes to fabricated supports.
Metal rings of uniform size and reasonably accurate roundness have many applications in rolling ball work. Nicholas Carter presents the following method:
If you make a coil of the brass wire by bending a length of it around and around a mandrel , you can then cut 1/2 circles from it quite easily. You can even make the mandrel oval or square depending on the profile of "U" you desire. Cut lengthwise to make rings, then cut each ring in half.
