I am making a coffee table and went out of town for 2 weeks right after I put together the legs/aprons w/ mortise and tenon joints. Came back and it warped slightly so there is an 1/8th to 1/4 inch lift from two of the table legs, diagonal from each other. It is easily pulled back into shape with very minimal pressure when pulling on the legs that are resting on a flat surface. I was planning on using z fasteners to secure the top to the base. Is it possible to just apply the slight pressure to get it back into square and secure the z fasteners? I was also planning on finishing the top and bottom separately for simplicity but if I need to slightly bend the base into shape should I just put it together and finish it as one piece? It's all cherry that will have BLO>shellac for color>poly for durability. This is the first woodworking piece I have made outside of frames so it is largely just a learning experiment that will be a bit more useful than something that hangs on a wall. If a suitable fix is something like adding brackets to the underside of the table is the best solution I've got no problem doing that. Thank you for any advice.
