Sorry for hijacking this thread, but the discussion of machining pulleys with custom belt groove profile got me thinking the following.
A hypothetical question here:
What would the demand be like for heavy duty (startomatic style with kidney cut out) flywheels, made exactly to the original Lister drawings that would also be available in the following options:
1), Version suitable for use with original single cylinder Lister CS engines (out of balance flywheel).
2), Version suitable for Listeriod engine with internally balanced crankshaft, also suitable for twin cylinder Lister CS engines ( fully balanced flywheel).
3), Taperlock hub mounting as an optional extra.
4), Flywheel rim machined for twin vee belts or serpentine belt groove profile as an optional extra.
5), Shrunk on starter ring.
6), Flyheel hub drilled for suitable extractor bolt location when the need arises to remove a stubborn flywhhel.
