Lock and Extend Window Cranks 68 Trade Wind
This photo shows the two mechanisms for the 68 Trade Wind windows. The lower crank is one of the two (should be three, but the middle one is missing) used to unlock the window. Midway up the frame is the crank for extending the window opening.
It's kind of a both/and system, crank the bottom ones out until the clips are released by the metal tongue of the crank system, then extend the opening wider using the crank on the side of the frame.
The trouble with the side frame crank is that the little bar with the metal teeth is bad about breaking off. I have a broken piece I keep around until I find out how to reattach it, or find a replacement (good luck, right?). It's not difficult to re-engage the remaining piece into the gear.
For a cross-wind situation, it's nice to crank the bottom locks out just as far as possible while keeping the clip engaged, then roll a little tension out -- a very little bit of tension -- with the side frame crank. This can be just right for a little breeze in cool weather. If I had a Fantastic Vent going, it might make air conditioning unnecessary except in deepest July and August heat.
One more thing. This photo also shows the plastic replacement window currently installed. The trim around the window is chopped up to fit in line with the window clip. The glue or silicone used to stick the trim to the plastic is failing. This has to go.
