Tools Maintenance and Workshop Management
Domain 8 tests upkeep of hand tools and machines, plus the layout and running of a small bindery.
Sharpening and care
- Knives and plough blades: bevel about 20–25°, hone on a stone, finish on a strop; a sharp edge cuts with light pressure and follows the rule.
- Guillotine blade: rotate or replace on a written schedule; keep the clamp face clean and dry.
- Bone folder: clean with fine abrasive and burnish; never soak it.
- Brushes: rinse PVA out in warm water and shape; starch brushes rinse in cold then warm water and dry flat.
- Needles and awls: light oil, silica gel in storage, discard rusty needles.
- Presses and sewing frames: oil screws lightly, check threads, keep tables level and dry.
Workshop layout
Arrange zones in workflow order: store, cut, fold and punch, sew, glue, dry, press, finish, despatch. Drying racks and presses sit beside the gluing bench. Store paper flat and off the floor in labelled bays; support boards so corners do not crush. Rotate stock first-expired-first-out, use job cards, and apply 5S: sort, set, shine, standardise, sustain. Set reorder levels for adhesive, thread and board.
Worked example
A PVA brush is left hard overnight. Soaking in hot water swells the handle and splits the ferrule, so soften only in warm water, comb out residue, reshape and dry flat. Prevention is simpler: rinse within ten minutes of use.
Traps
- Oil reaching a brush or a paste batch.
- Water on the guillotine blade or bed, causing rust.
- Paper stored upright without support, bending corners.
- Unlabelled adhesive batches.
- Sharpening at too shallow an angle and losing the edge.
