components
General manager Martin Branch says that they were
approached by a company that wanted to replace the
distributer in 1952 255 GT Ferrari as parts were no longer
available and the drawings couldn’t be sourced the only
option was to Scan the existing part and redraw and
reverse engineer this. We were asked for 20 units although
their requirement was for 2 completed units they were
confident that they would be able to sell the extra 18 units
as this engine requires of two these units.
One of the main problems was that the customer wanted
the main shaft and outside flange to be made from one
solid billet of material whereas the original was made of 5
parts both turned and pressed components
With some careful programming on one of our twin spindle
Doosan machines and the experience of our engineers, we
proved that it was more than able to cope with producing
the complex part.
The diameters on both ends of the shaft were ground
between centers and bearings were fitted.
The main body was also to be made from a single billet of
material so yet again it was scanned and redrawn before
any machining could be done.
The Points Cam again had to be scanned and redrawn
this had to be perfectly machined as if it was quarter of a
degree out of position the engine would not start and this
could result in serious damage to the engine.
Again some complex programming was involved, yet again
our twin spindle machine and experienced engineers
coped with this.
The parts were then checked by Colpa Precision’s
inspection department and were passed off ready for
dispatch.
Within a couple of hours after the parts had been collected
by the customer he came back to let us know that when he
assembled the twin distributers to the 1952 255 GT Ferrari
and fitted it, the car roared into life first time .
