This bookcase had to be designed for a Church, and be movable. It also had to fit comfortably against the back of pews when been stored.
I used European white oak which i quarter sawed myself,
the shelves sit 90 degrees to the face edge.
I made hold down blocks for the top, any screws used were solid brass SH and facing to heaven!
The bookcase is movable on castors.
Coated with sanding sealer and finished with about 8 – 10 coats of clear wax.
-- I cut it twice & it was still too short
