Photo of Webmaster's model in progress.

The motor faced the stern, not the bow as represented in the model.

There are three solutions for this vent.

For All Three

1. Cut off the gluing tab and angled duct on the side of the motor housing.
2. Fashion a duct from scrap plastic or sprue and file a curve on the underside to match the curve of Vent 11 that it will be joined to.
3. Whichever option you use the completed assembly to the deckhouse roof just slightly forward of the suggested location. Make sure the rear of the vent covers the tab hole.

Cut the top curled section off the lower motor unit. Turn this 180 degrees and glue it back on to the motor unit so the curl is now pointing away from the motor.

Option 2

1. Cut the whole curl vent from the the motor unit. i.e. the cut should be up and down behind the motor unit. Reshape the bottom of the curl vent as seen in the diagram above.
2. Scratch build a left handed motor unit as described in the Motor Unit section of the Vent Overview.
3. Glue the curl vent onto the motor unit with the curl facing forward.

Option 3

1. Cut off and reshape the curl vent as described in Option 2.
2. Now you need to make the existing motor unit into a left handed motor unit.
3. To do this you need to square the bottom and move the curved section to the opposite side.
4. To square up the curves take two pieces of scrape plastic the same width as the housing or slightly greater (Evergreen 2mm sheet works well). Cut small squares approx. 7mm x 7mm and then cut these in half diagonally, you will need three triangles. File a curve in the center of each diagonal. Keep testing them against the curves of the motor unit until you get them just right then CA glue glue the curve of the vent to the hollow in the plastic triangle.
5. When dry trim off the excess plastic and file square.
6. Now file the curve on the right hand side of the motor unit.
7. Glue the curl vent onto the motor unit with the curl facing forward.
