I am building a set of exterior storm doors that consist of a rail and stile frame with a curved top piece. One of the stiles needs to connect to the curved piece. See the attached image below. The joint in question is circled.

It will be end grain on the stile and coming into the side of the curved piece at an angle to the grain. I plan to cut the curved piece out of a wider board or, more likely, a glue-up. I showed that on the right side of the picture.

I’m set on typical mortise and tenons for the rails at the bottom and for the top end of the curved piece, where it attaches to the taller stile. Is a mortise and tenon best for the circled joint? If so, I may need to have an offset tenon because of the curve.

What is best for this joint, please? Thank you for your opinions. Gary

M&T is what I would use.

+1 to both comments above.

You could do a loose tenon if you don’t want to mess around with cutting a tenon on a curved piece.

A bridle joint has more good gluing surface than a M&T. I would fit the joint before trimming the upper piece to shape. I would put the tongue on the top piece, and the slot on the vertical piece, so the visible joint line is vertical, to match the other joints. If you want to pin it, pin it from the non-weather side, not through.

If you M&T, tenon the end of the top piece into a mortise in the side of the short stile, again to keep the visible joint line vertical like the other joints.
