If you have some way to make a lot of sawdust (power sander) then do
that, using the cutting board as a source -- it probably could use a

Why waste good epoxy by using garbage fillers?

Micro-balloons are the low cost filler of choice.

They fill without reducing strength.

Not only do they fill, but they also *fill up* -- at least, the ones
where their tops wear off do, because they are hollow. How do you clean
out the food residue (and resulting live stuff) that then gets in there?
