Steel Shaft, 30 mm: Round Bar Turned Between Centres
A shaft carries gears, wheels and bearings, and it has to be straight, round and true to size where they fit. Turned between centres from a forged round bar, it can be taken out, checked and put back without losing its axis.
The picture: a steel bar being turned between centres, driven by a lathe dog.
