Cut and slide the board back in
place and attach all the floor boards with screws through the sides.
(Be sure to pre-drill before driving in the screws.)
Attach
the 1" x 2" corner braces to the inside back of the frame using
1-1/4" screws. Then screw the top board to the corner braces to
complete the back.
Make the angled sidepieces by holding a
24" fence board on top of one of the existing sides. Use a straight
edge to draw the angle from the top back down to the level of the
front. Cut one angled board for each side.
Attach the angled
sides to the frame with screws through the back and one more through
the tip of the angled board. Add a vertical brace in the center of
the each side and secure it in place with screws through both
boards.
Remove old hardware from the window, then prime and
paint any exposed wood. Attach three hinges to the back of the
frame, then attach the window to the hinges leaving equal overhang
on both sides.
Make an arm (to hold the window open while
working inside the box). Drill one 1/4" hole through the three
layers: the side, the vertical support and the arm itself.
Pass a carriage bolt through the hole in the side, place a
washer on the bolt and then pass the bolt through the support arm.
Add another washer and finally a nut. Use thread adhesive to lock
the nut in place leaving the arm a bit loose so that it can move
freely and easily.
Voila - your very own cold frame!
But here's the thing. Don't plant your tomato seeds too
early or they'll be ripe earlier than anyone else's and then they'll
be gone earlier than anyone else's and then next winter is going to
seem even longer.
