Finish gluing the doors and hinges to their frames and the the hinges in the slots in the door jamb assemblies.

Drill a 1/8" hole centered (in the plywood) near the bottom of the opening in each assembly.

Holding the doors shut push a piece of 1/8" aluminum or Brass tubing through from the back side to make a mark in the door frame.

Drill a 1/16" hole in the center of this mark. Use a drop of gap filling CA and insert a Dubro 1/16" ball link in each hole.

Remove the tubing and drill another1/16" hole all the way through the tube. Slide a piece of standard Glow fuel line over the end of the tubing you just drilled and drill thru the fuel line. Glue a rod or small screw in the hole, capturing the fuel line to the brass tubing.

Slide this assembly through the hole in the door jamb close the door compressing the ball link into the fuel line. pull the brass tubing so the door is held tight to the frame. Adjust the fuel tubing as need to get a tight fit. You may need to cut the fuel line below the capturing rod/screw a bit so the door is tight to the jamb.

When satisfied glue the brass tubing to the plywood using gap filling CA. Check the operation with your finger nail under one edge of the door to open it.

Cut the excess brass tubing (sticking out the back side) off on both doors.
