Don,
I think your Idea would work, use 8 x 8 cut offs approximately . 8 to 10 inches long band, glue or peg them together and throw the axe at the end grain. You would end up with a square or rectangular target to paint circles on.

You mean kind of like a big butcher block... you know they say that's how block planes got their name: from smoothing end-grain butcher blocks.
The only issue I see w/ a big end grain "glue-up" is you'd probably have to keep it out of the weather. 8x8s would move, shrink, expand and bust each other up.
