rmorris,
Filling holes in the Ambrosia Maple wasn't hard. The veneers are only .030 thick. When I applied the glue I just made sure I worked it alot more at the holds making sure I pushed it in the holes instead of swiping it just over the holes.
Then as I was ready to set the veneer on the stack I double checked both sides of the veneer to make sure the holes were full.
Pretty simple and no problem at all.
Once the limbs were out of the oven they only look like dark, dark grey to black dots.
