Sometimes you need to drill a hole in the direction or position under your aluminium piece,which you cannot see. Plastic surgeons use a direction finder to fill tissue expanders through the skin. The direction finder localized a small magnet incorporated in the tissue expander. Tape a very small magnet under the aluminium skin and the direction finder shows you exactly were to drill your hole.
The direction finders are disposable. Every plastic surgeon can give one to you.
