'30s Supecharged Wolseley Hornet, a million last painstaking jobs as we build this special from ground up.
Designs roughly put to paper, sometimes refined later in the evening, a must where stress calculations are necessary and sometimes created from the sketch alone.
Pre-War Peugeot. Conversion to shell bearings:
As with all modifications, we have to think of any consequences of changing the design of a mechanism. Whilst changing from white metal to thin wall shells from a later vehicle will be more practical for future builds of this engine, the cost is not any less than a full white metal replacement in this first instance.
These connecting rods have been converted many years ago and the whole engine was then stored. As as we build the engine we have to be very aware to make sure all is correct. We have had to machine and hand fettle the tang locations for the new shells. There is a small problem, as the housing mating surfaces go together they do not quite fully mate, the faces are fractionally out of true toward their edges. We now have to lap very carefully whilst keeping a watchful eye to maintain the housing tolerances within tenths of a thousandth of an inch. We mustn't forget to drill the tiny, timed oilway that feeds the cylinder bore for a very brief interval.. This is all very rewarding work, but terribly time consuming. We fettle a very small amount by filing the tang locations and lapping the face. We then apply Blue paste (similar to the use of a sooty flame in the gun making video elsewhere on this blog https://artinengineeringco.blogspot.com/2020/07/immerse-into-world-of-craftsman.html ) to the items, assemble, carefully torque together, strip, inspect and as necessary continue the process until all fit as near perfectly as possible. The whole meticulous process takes place under the vigil of an unforgiving ticking clock...
