I've used this technique and had a bit that cleaned up the wood but
also left cutter marks on the plywood.

After that ran test cuts with a different bit.

No problems.

You are correct, not all bits are the same. I prefer a to start with a
quality bit that is more likely to have an exact match between the
cutter and the bearing.

This isn't to say that a cheap bit will be off, but testing on some
scrap is recommended. We talking thou's here, so it's not something you
can see by looking at the edge of the bit or even using a straight edge
to check.

ALSO... if you're not perfectly square to the table, meaning there will
be a slight angle to the pattern bit, you can end up cutting into the
plywood surface. DAMHIKT. :-)

You can also guard against this by raising your bit *only* high enough
to cut the solid wood and not the plywood. It's tricky, but I've gotten
pretty good and fast at it.
