Reproduction Henderson Four Cases
Reproduction Henderson cases.
An original early '20s crankcase and sump were 3D scanned, then a CAD program was produced with "improvements" so as not to change external appearances.
The CAD program was used to CNC the patterns for the castings.
The castings are in Aluminium AC601, heat treated to T6 and are produced as original to the eye as possible.
To increase the strength of the crankcase and sump some wall thickness and radii have been increased internally, not obvious externally.
Mains oil pipeline is replaced by solid casting.
The patterns are capable of making original type 3 main bearing or 5 bearing cases, shown here.
The upper case will suit KJ.
The first set is about to be machined.
At this stage, we only plan to offer raw castings, as pictured.
The price is US$4,500 for both case, or you can have a upper case only for $3,500.
