Not sure I understand, still fairly new to turning. I glued the nine pieces together. Put it on the lathe and turned it round. Then cut a tenon on both ends. The used a parting tool to cut the top from the bottom. What would be a better way to make it to not have the problem you are talking about?I'll be curious how that lid fits this winter. Some of the growth rings are opposing each other.
I've built furniture for 50 years. I know to fit drawers and doors looser in the winter because wood swells across the grain in the summer and shrinks in the winter. I also know you don't glue a frame around a solid wood table top because 3' of wood can shrink or swell over 1/4" over the seasons. When I see laminations, I hope to see all the grain running the same direction so all the wood swells and shrinks together. When I look at the end grain of your lamination, I see growth rings perpendicular to the piece of wood next to it. That means one piece will swell in one direction and the piece next to it swells or shrinks another direction. The pieces aren't big, and movement will be slight, but you could get a crack in the joint when the wood moves. It may also change the fit of the lid with a big humidity change. Wood is not inert, it constantly moves.Not sure I understand, still fairly new to turning. I glued the nine pieces together. Put it on the lathe and turned it round. Then cut a tenon on both ends.
