To Use Your Periscope in the Submarine
In the center of the conning tower cut a circle a little bigger than your periscope box. See Picture.
To make a periscope mount, take a piece of heavy cardboard. Cut a circle a little bigger than the one in the conning tower.
Set the periscope box on this circle and draw around the square box. Cut out.
Remove one mirror and slip the periscope into this circle mount. Replace mirror.
Put one end of the periscope through the hole in the conning tower, so that the mount is outside the box.
You can add all kinds of finishing touches. You can make a control panel on the inside of the conning tower. You can add an anchor, and even paint on a name.
