   Any suggestions on how to case two windows that meet in a corner? There is about a 3-inch space to each window, but the window casing is about 3-inches. With the thickness of the casing, both pieces cannot fit. I was thinking to just treat it like an inside corner (like molding) and miter and backcut on side. Any other ideas? These are "picture-framed" cased windows.

   I am trying to do the same thing 24 years later. As you said, the only solution I can come up with is to 45 deg. miter the length of the butting inside frame pieces. Does anyone have a better solution? I need to generally match the rest of the house, and I have three corner window sets.

   Added a picture. I am trying to picture frame with 2-1/4" colonial casing. One [left] side almost just fits for a 1/4" reveal, but the other [right] side is too small by about 3/8". If I cut one or both down [w/45 deg.] lengthwise, the 45 deg. frame corners don't match, and are funky at best. Is there an acceptable compromise or work-around?

   Picture of the casing would be helpful

   Well, can’t say I’ve ever had to do this but….
   Thinking of how 2 windows go together ganged…….side by side.
   You’d use maybe a thinner flat stock on the mullion. Thinner, no profile.
   The top and bottom casing would run around the inside corner.

   Now, 3” on each side of the corner might be too much.
   But what the heck, check it out.

   When you do decide and get it done, come back with a picture.

   Calvin, I admit I did not get it at first, but after reading it several times, that seems to be a reasonable work-around. Yes, thinner, no profile/reveal. Now I just need to find stock that is no more than 3/16" (small side of the casing). Thanks!

   Do you have a real lumberyard near you or a friend with a plainer?
   I’ve ripped 7/8” stock on a table but it’s dangerous and I wouldn’t advise anyone with 10 fingers to do it.

   Of course you should be able to find a good quality 3/8” ply (Baltic birch) and with a router and guide, and proper sized bit…..
   Shape one edge, rip to size(or close)…..shape an edge, rip to size (or close) till you have enough. Finish your pcs and rip to size and install.

   But then again, I’m a retired 75 yo carpenter with 2 good eyes and 10 full length fingers and toes. I’ve met several that don’t.

   Ahhh, you read my mind…..

   Round over (ease) one edge of the 3/16” flat stock.
   If it looks okay and will work, yahoo!.

   When installing window casing at corners, coped joints are used rather than mitered ones. Copped joints tend to fit better over time as they accommodate wood movement and reduce visible gaps. Make sure to carefully cut the profile of one piece so it fits snugly on the face of the adjoining casing. This technique looks cleaner but also provides a durable and professional finish.
