Assembly
- Use smooth untreated dry hardwood. The finished tool is for fabric repair and has no medical or food-contact function.
- Cut A as a 3 × 3 × 3/4 in blank; draw a 3 in diameter circle centered in it.
- Clamp outside the circle and saw away waste in small sections, leaving the circle line for rasping.
- Rasp the outer cap to the 3 in circle. Round the upper face perimeter smoothly while keeping a central flat underside for the handle socket.
- Mark the underside center 1 1/2 in from both blank reference edges. Drill a 3/4 in blind socket 1/2 in deep, leaving at least 1/4 in wood beneath the upper face.
- Cut B 4 1/2 in long, ease its lower grip end and trial its actual fit in scrap. Do not force it into the cap.
- Apply suitable wood adhesive to B’s lower 1/2 in insertion portion, seat square and remove squeeze-out. The exposed grip is 4 in.
- Cure for the adhesive’s full labeled time. Sand the cap through progressively finer abrasives until a scrap knit fabric slides without snagging.
- Insert the cap inside a sock and center the worn area over it without stretching the knit hard. Keep the sewing needle away from the grip hand.
- Remove the tool, count needles and brush away loose fibers after each repair.
Checks
- Cap diameter 3 in; blind socket 1/2 in deep.
- Handle projection 4 in below cap.
- Scrap knit passes over the cap with no snag.
Cleaning and maintenance
- Keep dry and smooth.
- Replace a cracked cap or loose handle before use.
