Balancing Act.

At every turn we find another hurdle, mainly in our learning....this time it's crank balancing. Now Steve is geting ready to finish off the cranks we needed to consider the balancing, the amount of theory and formuli available on this subject is mind boggling.
We being simple folk will keep it simple, follow some guidelines to get a measure and then pocket the crank as per this model. We can then get it dynamically balanced later on.
