    Default Matching old moulding trim on a window

    I own a house built in 1870. The front door has gabled(rounded) shaped windows. Over the years the molding over the window has fallen off and is lost. About two feet of it is missing. I went to our neighborhood lumber yard and they had some molding that was close(but no cigar)...but it turns out it is kiln dried and kiln dried lumber won't steam and bend to match the curve of the windows. So how do I get something to match the old wood molding that I can bend to fit the landmarked windows?

    thanks for the help!

    I would repair the existing molding with plaster. First use a profile gauge to determine the shape you need (see pic). Then trace the profile onto a drywall knife (for a small job a plastic knife works). Cut/grind the profile onto the knife. Staple expanded metal lath on the area to be plastered. Use the profile knife to shape plaster. Sand, reapply, sand... as needed. Prime and paint.

    My examples are other millwork, but it works the same. This is a traditional way to do curved molding.

    All the best,

    Doesn't that make the knife a little tough to use the next time you have to patch drywall?

    You just have to like a heavy texture:

    In addition to the support of the wire lath, it is good to use a bonding agent like this one:

    A plastic knife can be cut with a scroll saw and cleaned up with files and sanding. If you want a metal knife cut and ground for your profile, let me know. For $75 I can make a custom knife for you.
