Okay, I'm thinking about using this block to make a transition, 3" aft end, 1.9" forward end, about 7" long. There is a small problem...
...that ends up being a deep problem...
The ruler goes into the narrow crack almost 3" deep. Crack will be exposed as I file/sand, regardless of which end of the block is used for forward/aft end.
Possible solutions:

Possible solutions:
- Fill with epoxy before turning.
- I can do this--thin epoxy with slow curative will work, I'm sure---but turning the transition will be a bumpy ride since epoxy is far harder than balsa.
- Mix q-cells/microballoons with epoxy, fill the crack.
- It'll be quite difficult to make a mix that cures about as soft as balsa, but thin enough to pour into a 1/16" wide crack. I won't know if it's filled the crack until after I turn the piece.
- Attempting to 'knife' a putty-like mix into the crack is going to fail. No way can I get a stiff mix to the bottom of that crack.
- Turn the piece, fill the crack after turning to shape.
- I expect that would also leave quite a bump where the sandpaper or file hits the crack. Symmetry will take a hit.
