Classic bevel-driven lay-out

This object is not a model as such, but built with factory parts
of the classic L-twins bevel-driven layout.
The arrangement consists of a lower/shorter transmission shaft
with bevel gear and a upper/longer transmission shaft with bevel gear.
Both shafts are Oldham-type coupled. Four bevel-gears in total are driving the 900 SS/SD camshaft.
It is amazingly light to operate.
