I am in the process of repairing the old wood double hung windows in my house. I've pulled off the stops and removed the lower sash, however when I look to remove the parting bead, it appears the upper sash has a groove in it that over laps the parting bead. How do I take out the parting bead with the upper sash pinning it in place?
I hope that makes sense, If I can get a decent photo I will post it.
Thank you for your advice.
