    Question Fireplace Mantel Joinery Question

    Any suggestion on how to construct the frames for this inset panel design in a way that produces a strong tight joint with good alignment?

    What joinery would you use for the circled joint? It doesn't seem substantial enough for biscuits or Dominos. Pocket screws might work? Is the panel material likely to be 1/4" MDF?

    Assuming the molding inside the frame is applied and not part of the raised trim, I would use a half lap joint. YOu should be able to glue the trim to the substrate hat makes up the panel which should provide more than adequate strength.

    You might consider on-lay construction. That is, the "panels" are actually one big piece of sheet goods with the moldings fastened on to the face. The moldings would likely be multi-part. There would be a piece which has a simple rectangle cross-section -- maybe 1" wide by 3/4" thick?. That does the basic layout. Tucked inside that are the moldings, each with a miter on both ends. You can probably source the moldings without having to make them yourself. Glue and pin-nail them in place. Painters caulk to fill gaps, paint over everything.

    I agree with Jamie, that would be the easiest way to have it come out looking good. How deep is the shelf on top of the mantle?

    Also agree with Jamie, moulding attached to the face, not complicated.

    Haven't decided for sure. Probably 9" or so. Thx for the the on-lay suggestion!
