Hi,
I'm building a keepsake box for my wife for Christmas. The lid will be made like a picture frame with a floating panel in the middle. I know that if I used a veneer glued to plywood, I could make it a tight fitting panel, but I used a solid piece from a neighbors fallen tree. Since it's a solid piece, I know that it needs room for expansion. The pieces for the lid are just dry fit for now but I can tell that the center panel will slide around. What should I do to prevent this? My thought is to use a couple small pieces of flexible vinyl tubing in each side of the picture framing. This would hold the panel in place, but since the vinyl tubing is flexible it should allow for wood expansion.
Any other ideas? What is the standard practice for this? I've included a couple pictures just to show the lid top dry fit. Obviously nothing is finished yet.
Thank you,
