Video showing the re-grinding of a worn 1956 P4 75 camshaft on a 1940's John Lund camshaft grinder. All old camshafts are bent and twisted and have to be straightened first on a flypress. They are then checked between centres to allow no more than .001" run out before they can be put onto the cam grinder.

Each lobe is re-profiled from a master which is run on the LH side of the machine. This governs the grinding of the lobes by tilting the bed as it rotates the camshaft against the grinding wheel. The lobes are inspected carefully to ascertain when the grinding can be reduced to a point when grinding action literally 'sparks out'.

After all of the lobes are completed, the cam is then sent for hardening. After which it will need to be checked and straightened due to the hardening process. Finally it will be chemically plated.



Video showing the main milling operation of facing the output ports of a Rover P6 V8S cast iron exhaust manifold. Cast in the midlands and machined within our works on a 40 year old heavy duty Polish miller.

This is just one of 10 machine operations that will eventually turn a rough casting into a finished product ready for sale.
