Our trusty Arca Swiss B1 ball head gave up the ghost recently after over a decade of service (see Figure 1). But as we soon discovered, all is not lost. Rather than buy the new Arca Swiss Z1 head which uses a different panning clamp, we had the good folks at Precision Camera Works completely rebuild the B1. For a fraction of the Z1 price, you can rebuild your B1 and make it much lighter.
