Topic tags/keywords: millwork wainscoting window trim

In a recent thread, I asked about milling trim for base boards, windows and doors. So, now I’ve found another issue:

The windows are very deep and their wooden frames protrude past the drywall roughly 1/2”.

The old trim had a more rustic look than we’re going for now: the original trim was simply 1” X 4” rough sawn
red western cedar and to create the reveal where it overlapped the wooden frames, we ripped strips to go
under the cedar creating a reveal on both edges.

With the ogee milled on the walnut, there isn’t enough thickness to form the reveal on the wooden window
frames without building up under the walnut as we did before.
To create the reveal and have the ogee edge on the window trim without building up under the walnut,
it would have to be installed backward—thick edge at the window, thin edge away from the window.

How would you solve a situation like this?
Would you install the millwork backward OR build up underneath it—which would end up making the overall window trim look 1-1/4” thick—or is there another option I’ve missed?

If I build it up so I can create the reveal, do I mill the stiles to taper gently along their length so they’re 3/4” when they meet the side of the base board?
If I install the window trim backward, I’d could the stiles to the same thickness as the top of the baseboard
and that’d make it look intentional wherein we’re creating the wainscoting.

I’d like to hear y’alls thoughts.

A few pics of your conundrum would be nice.

If you have extension jambs on the windows you can pull them off and rip them down narrower and then re-install them. You can hand plane the windows down flush to the drywall it there aren’t too many. (watch out for the nails that hold the extensions on) You could hold something thin and stiff like a piece of aluminum on the wall and flush trim with a router (again watch for nails). The main thing is to get the wood down to where it is just a little proud of the wall and then install your trim.

These are Vetter double-hung wood interior, alumiclad exterior windows.
I’ll have to call Vetter and learn if the extension jambs can be removed with the windows
already installed. If I can take them off and re-install them without too much trouble,
that’ll solve the whole matter.
Thanks Mike.
