At home flywheel balance....

I should clarify, this won't be about balancing the whole rotating assembly, it's about changing a flywheel from neutral balance to external balance. the one in the pic is my 360 reference wheel. Usually when someone asks about this, they are shown the Mopar diagram and then told to head down to a machine shop and have it machined as per the diagram. I'm just investigating whether another solution can be found. I'm also interested in the how accurate the jig I made is.

So basically you need to add weight to a neutral balanced flywheel opposite to where the holes are drilled in the external balanced flywheel but there's the all important question of how much weight to add and where to place it. I don't get what the jig is for, are planning on testing different weights at different distances from the center?
