Topic tags/keywords: frame and panel

I’m making a bed headboard, it’s a frame-and-panel design. There are 1” mortise and tenon joints in each corner and a center stile with a tenon that fits into the groove for the panels. Should I glue the panels also, or just glue the joints? Will it be strong enough if I just glue the joints?

In frame and panel construction, the panels should be able to “float” to minimize problems due to expansion and contraction.

In my personal experience, solid wood panels (i.e. raised) should definitely float, The majority of my flat panel doors are made with 1/4” (5.2mm if you insist) and I don’t concern myself too much about them. Plywood won’t expand and contract as much as solid wood.

When I glue up any frame and panel, I use a dab of glue in the center of the top and bottom rails to keep the panel from shifting if/as the stiles expand and contract.

If your panels fit loosley in the frames, use some space balls so they won’t rattle. Rattling is bad enough in a door, but would be truly annoying in a bed headboard.

The joinst should be strong enough. If you glue the panels they normally swell with humidity changes and push the joints apart. Leave the panels loose. Make some little silicone caulk drops about the size of BB’s. After they cure insert them into the grooves then install the panels. These will stop the rattle but they will compress if needed. Use then on at least 2 adjacent sides of the panels. Good luck with the bed. Post some pics when finished.

If you glue a panel at all, just glue a dab in the center of the panel. Do this at the top and at the bottom. This will keep the panel centered, and let the sides expand and contract. If you glue a solid wood panel in a frame, it will crack.

Same as above, don’t glue them, make sure they are slightly undersized and use silicone spacers to keep the panels from rattling. I’ve also seen panels with a drop of glue in the center of the panel top and bottom assuming the grain in the panel runs up and down, it allows the panel to expand but the panel stays centered.

One thing you can do to not ever have aloose panel is to use the little rubber balls or some of the very thin strips of rubber in the all around the panel.

Yup, the whole purpose of frame and panel is to allow for movement with humidity changes. Gluing the panels would go against the whole thinking that makes frame and panel a successful design.

I’ve not seen this mention but a few dabs of silicone calking, in each side of the panel has worked well for me.

I like 3/8 self adhesive foam strips to stop rattles. (some of the double glazing industry uses it)

That’s the practice I’ve always followed…works well.

If the joints are correctly made, plywood panels shouldn’t need to be glued. They should be treated the same as a solid wood panel; float.

Wow, thanks everybody for the input. I’m using 1/2” oak plywood for the panels, the good stuff from the plywood supplier (only three layers total). I’m going to go with the majority opinion and not glue them. That is what I would have to do if I had solid panels. Plus, I want to prove to myself how strong those mortise and tenon joints are. I will put the silicone beads in the grooves. Great idea.

Umm…. 3 layers in a half inch? I have luaun that has more layers than that.

I would expect 5 layers minimum and maybe 7.
