That's what xargs was invented for.  Try

find /cygdrive/d/sandbox -newer /cygdrive/i/backups/_sandbox.full ! -type d -print0 | xargs -0 ls -l

Here you can use something like

find /cygdrive/d/sandbox -newer /cygdrive/i/backups/_sandbox.full ! -type d -print0 | xargs -0 tar czf /cygdrive/i/${TODAY}_I_sandbox.tgz

or even

find /cygdrive/d/sandbox -newer /cygdrive/i/backups/_sandbox.full ! -type d -print0 | tar -T- --null -czf /cygdrive/i/${TODAY}_I_sandbox.tgz

HTH,
