Parallel Engineering

A customer brought in their MK3 Commando to go through the frame/rolling chassis wheel alignment process. He was aware of serious rear wheel mis-alignment. I discovered the rim offset was approx 1/2" from where it should be and recommend a new rim with spoke hole angles drilled to suit a MK3 Commando rear hub. He took the wheel back to the Centrally located Wheel building establishment where the wheel was originally built. I was surprised when the wheel was returned with the same rim. The offset was now in the right ball park but all the drive side spokes now feature a double/s-bend. Wheel spokes are designed to work in tension and therefore must be straight along their length.You couldn't make this up.

Two photos showing the before and after of the latest bike to be in the workshop to go through the alignment process is a 1971 750 Norton Commando. There was additional engine and transmission work and generally putting things right.
