We reproduce all our sprockets using 3D scans of originals when they are available. We use 1045 or 4140 medium carbon steel and heat treat our front sprockets to HRC +50.
We can also reproduce sprocket combinations to suit modern chain profiles.
We use an Einscan 3D scanner and software for precision reproduction of original sprockets
The 3D scans are sectionalised to extract an exact profile of the original sprockets for CNC programming
Machining is completed using our CNC lathe and 4 axis CNC mill
An exact replica of the original. Even details like the indent from the original press are retained
