So I recently salvaged a 5’x2’ metal cabinet to serve as a home solvent cabinet. Same one that I recently made a NFPA tag to go on.
The cabinet has a simple spring catch in the middle of the doors that’s not especially strong. Decided I wanted a more positive catch. Made a pivoting hatch dog to go at the top in the middle were the doors meet.
Made from black walnut with simple lathe turned knobs and a wipe on poly finish. Cut a couple of PTFE washers to sandwich the dog to ensure a smooth pivot. Lined the back of the dog with self-adhesive flocking paper so the it would not scratch the paint on the cabinet. Double stacked nuts locked together to ensure it doesn’t unscrew with use.
