Watch this video to explore design considerations. Solid wood case construction must take into account wood movement. Wood expands and contracts across the grain and does not along the length of the grain. When wood is glued across grain over a long span, it will split when it contracts. NOTE: The drawer frames and the back are all pre-assembled. The back is a mortise and tenon frame which contains six floating solid-wood panels.
Clamping rehearsal without drawer frames.
Floating panel back assembly squared up the case.
Watch this video to view my clamping configuration. Gluing up a case this large requires a lot of clamps. This is typically a situation where I wish I had more clamps. If I had more clamps across the back edge, I could have closed the rabbet joint more consistently on the back edge. However, that’s being pretty picky. NOTE: I assembled the case in a vertical position which allowed the best clamp access. I made a mistake by resting the whole assembly on a foam mat. This allowed a bit of inaccuracy where the back lined up with the lower left corner and the mat obscured my view of this issue.
In the next blog entry, we’ll explore face frame construction and glue-up.
