Topic tags/keywords: tongue and groove panel rabbeted frame

Alright folks, I came across a new challenge… Building a set of cedar exterior/interior doors, where the red cedar tongue and groove panel is inset to the frame via a 1/4” deep rabbet. Original intent was to assemble the panel into the frame in the same fashion as a t&g wood floor—place/seat the board, blind nail, seat next board, nail, etc. However, I fear I may have cut the boards TOO precisely. When dry-fitting the panel to the frame, I had to compress the panel a bit to compensate for minor warpage on a few boards. Now, the panel is in place, quite snug, and I don’t know that I can easily remove it for final assembly. I see two options here: 1)Remove the panel as carefully as I can, chancing a break at a tongue or groove, and doing final assembly HOPING that I compress each warped board sufficiently for the final fit, or 2) Nailing the panel as is, and going behind and filling/masking the nail holes… Any other ideas or advice?? I’m not unfamiliar with t&g, but this is my first inset t&g…

If this is dry-fit only, can’t you get the stiles and rails apart and then remove the panel parts? I guess I don’t understand the issue.

Door panels are not the same as T&G flooring, especially exterior doors, subject to serious seasonal humidity changes. They should not be installed too tight. They need room to expand/contract. You can put a single nail in each board—-too keep it in place—- but you should leave some room for movement.

The frame itself has gone through final assembly, as I doweled the rails and stiles for strength. The issue lies with fastening the t&g panel to the door frame. Expansion and contraction is accounted for, I just had to compress sections of the panel to deal with warped boards. Also, in order to further control expansion and contraction the doors will be finished with wood conditioner and spar varnish.
