Ten swabs, perfectly sized for pinewood derby wheel bores. Use these swabs to polish wheel bores and to start the graphite lubrication process.
Bore Swabs are softer than pipe cleaners and avoid the risk of scratching the bore with the pipe cleaner wire.
- Cut a Bore Swab in half, then insert into your drill chuck. If the drill chuck does not clamp firmly on the swab, wrap tape around the swab shaft to increase the diameter.
- Apply Bore Polish to the swab, slide a wheel onto the swab, and polish.
- If desired, apply graphite to a clean swab and rotate it in side the wheel bore to start the lubrication process.
