How do I finish the open end of a chair rail?

Question

I helped a friend put up a chair rail in his house yesterday. It turned out great, except that neither of us knew what to do about where it met the window. Since the window didn't have trim around the outside, the chair rail kind of dead ends without any end piece.

Here's a photo:

Any suggestions on how to finish this? I know it would typically be cut at a 45° bevel, but since it's hollow behind the rail, it wouldn't look right unless it was caulked or spackled.

Answer 1

You could do this as an outside corner, with just a little piece of rail.

I did this with some baseboard right beside a closet (that I didn't want to put trim around), and it turned out well. (Taking this picture also reminds me, I never did quite finish cleaning this all up).

The hardest part of doing this is cutting the edge piece so you get a perfect corner.

1. Cut the piece (usually there's a scarp piece around that will work). Go longer rather than shorter.
2. Use wood glue or a construction adhesive (like No More Nails) and a clamp to attach it, with the edges meeting. Let it sit overnight to dry.
3. Sand off any excess glue that came out.
4. If needed, sand down the back side so it's flat (if you cut it a bit too long). A couple seconds on a belt sander is perfect.

That's really all there is to it. In your case, you may want to also sand down the front corner a bit so it's smoother, rather than sharp and likely to poke someone.

Answer 2

I have done this 3 different ways:

1) Bevel the edge and sand it to make even smoother rounded edges. This actually looks okay and is the easiest, unless there is the hollow back problem like you have. You'd have to fill it like you mentioned with a custom shim-type piece.

2) Cut and prepare the edge as in the post above by gregmac. That looks great and it's not a lot of work.

3) You can use a block piece to really add a decorative touch. This is great in formal areas like a dining room. Just add a block piece like the one in the link at the end of the railing.

I found a great picture of option 3 with a Google image search.

Good luck!

Answer 3

In this case I'd be tempted to just fill the end.

Or, if that would still look a bit messy because the end of the dado isn't smooth, cut as piece of thin plywood (or mdf) to match the profile and stick that on the end.

Answer 4

Put trim around your door, and then but the chair rail into the door trim. If it sticks up above the door trim any, miter the end a little.

Otherwise, cut a piece of chair rail about an inch long and mitered, then miter the end of the longer piece and glue them together to make a return.
