I just made a 62" x 20" picture frame and have some questions for you guys.
Normally when I have long boards, I try to get them pretty flat all the way along the length, but I learned early on that if I am doing a glue up, I can't expect to get a 62" board completley flat. What I mean by that is I would have to start with probably a 6/4 board to get it completley flat down to a 3/4 board. The issue with that is that there is potential that the wood would warp over time because of all of the wood removed to get down to 3/4.
So now, I took that knowledge and decided to try making my picture frame. I used 4/4 boards that were S2S. In reality they were about 1/16 thicker than 3/4. I tried running it through the jointer and then planner, but there was still a bit of a cup in the wood. This all resulted in the frame not being completely flat, but having a slight twist in it.
What should I have done? Started with a thicker piece of wood?
