The latch

I chose a latch that looked like the originals, but with a brass finish that would match the screws for the pulleys and the lower sash weatherstripping.  The latch secures the sash meeting rails together and prevents the windows from being opened.
Here are some pictures.

Painting the Pulleys

The pulleys for the sash weights looked like this.

The original finish was a tan lacquer.  The lower sash pulleys were painted green.  I stripped the green paint off where the sash moves which includes the pulley.  I couldn't match the tan look of the original, so I decided to paint them both with black lacquer spray paint.  I removed them and used fast acting paint remover to clean the paint off the pulleys and a heat gun for the wood.  The screws are being replaced with shiny brass colored ones to match the fixture latches.  I made a holder out of cardboard so I could paint the edges that will show when installed.  The pulleys and the axles were masked off.  Here are some pictures of the process.

Here they are after installation.

Weird Walls

The walls in this room and all of the 2nd story are made of a fiber board nailed over the studs.  I'm going to put up textured wallpaper over the walls.  The old cloth tape and wallpaper that is covering the nails and seams is cracked and bulging out, so I have to tear it off and redo it.
Here is what it looked like before.

 This is what it looked like after the tape was removed.  It shows the original material and the nails.

This is what it looks like after the 'tape and mud'.  Pretty good for a beginner!

Painting the sashes

Before painting, the area must be cleaned of any sawdust, and removed glue or glazing pieces. I use a water spray bottle and some paper towels for the work bench, and a floor vac with a good bag and filter for the floor.

The glazing side (outside) was painted white. the inside was painted a light green color. I used interior semigloss latex for all the paint because water can be used to clean the brushes and stir sticks, semigloss hides brush marks, and interior paint is better for cleaning. I made one color mistake. The bottom edge of the top sash should be white, I painted it green. I don't think anyone will notice it though because its 30 feet up and behind aluminum storm windows.

When I started this project the main goals were to have working windows that didn't leak, rattle, or stick. Satisfying the first two could make the last goal difficult. The best way I saw to prevent sticking, was to not have paint to paint contact. I used painter's tape to mask off about a 1/2 inch of the side rails on both sides of the upper and lower sashes. I also masked off the areas of the channels and parting members on the window casings that would have friction from moving parts, but I'll write about that when I get to the upstairs room work.

I masked off the glass too, even though some people just scrape the excess paint off the glass with a razor blade. I find masking off easier. I used an angle cut brush with fine bristles to reduce brush marks.

You can see in these pictures the sash sides were left as bare wood.

 Notice the screw holes for the latch fixture in the upper sash. Very important!
