Building a Window Frame

How do you build a window frame for 2 wood windows so one opens and closes?

 

That's a pretty vague question. Are you talking about making a double hung window where one sash would slide up and down? Do you have the sashes? The sash is the part with the glass in it that slides up and down.

 

Yes a double hung window. If the sash is that rope then some do and some dont.

 

still wondering the answer to this question.

 

If your referring to the window frame with glass then I have that as well. Otherwise post pic of what your talking about.

 

The sill is a piece of wood cut like a parallelogram. Cedar 2x8 usually works well for this. Cut a 10° angle off both the front and back with a table saw. Then determine the wall thickness of the wall that the windows will be installed in. Rip your jambs that wide. Usually a 1x6 works well for this.

Lay your sashes out and if they have locks, lock them together, then measure their overall size. The interior measurements of the window will be maybe 1/8" wider and 1/4" shorter than the sashes measure. Let's say the sashes measure 23 7/8 x 53 1/4 when they are laid together. The inside measurements of your window opening would be about 24 x 53.

You'd cut a top jamb that is 25 1/2" long. Jamb sides would be 53 7/8" or so, when measured to the short point of a 10° angle. To build the jamb, you'd nail down through the top of the top jamb and down into the top of the jamb sides. You'd need to notch a corner out of each side of the sill to accept the legs, leaving 24" of sill in the middle. You'd then nail the legs to the sides of the sill.

You'd then attach the blind stop to the outside perimeter of the window jamb (1 top and 2 side pcs) The stop is usually 1/2 x 3/4. Glue and nail it to the jamb. Then lay whole window assembly down with the exterior side facing down. Place the top sash in place against the blind stop. Next lay a parting stop against the sash. The parting stop separates the upper sash from the lower sash, and it is full length vertically, when measured from the top jamb to the sill. It will probably be roughly 3/8" x 1/2". Press it against the interior side of the upper sash and glue and nail it to the jamb. Make sure the parting stop is parallel to the outer blind stop. Do this on both the left and right sides, then put one across the top. (the parting stop usually fits into a dado that has been cut into the side and top jambs and measures 1/2 x 3/4" but I skipped that part since it complicates matters.)

Then lay the front sash against the parting stop. See if both sashes will lock. If the sash seems too tall, you can trim a little off the bottom of the sash, cutting it at a 10° angle to match the sill. Once it closes and locks nicely, you are ready to put an interior stop on.

This window has no counterweights. It's a simple frame to hold your sashes. You can buy window sash spring bolts online and install them. The window bolts used holes drilled into the jamb to keep the window raised at preset heights.

Sorry if this seems complicated, but it's about the simplest way I can think of to explain it. And sorry, I won't be taking any pictures to show you how to do it.

 

Thanks. I'll give it a shot.
