Why dont we just build a window, Part Four

Success!

The window is largely complete. It isn’t installed; the sashes are currently installed in the frame, set up in my shop. It operates pretty well - I can slide the lower sash up and it stays in place, and I can slide the lower sash down and it holds position too. The upper sash tends to fall off about 1/8” when it’s in the up position, so I need to figure out how to increase the tension a bit on the balances. I also need to install weatherstripping.

The balances make a little squeak when the window is operated; I think the springs are rubbing against the frame. The fix for this would be a slightly deeper pocket in the sash for the balances.

I also want to wax the tracks in the frame.

Here’s the first picture - I’ll post more later. Click to enlarge.
