Wobbly Chair Dowel Hole Rebuild Sleeves
A snap-off sprue of six crush-ribbed sleeves for rebuilding wallowed-out dowel holes in chair and table joints. Drill the worn hole out to 12 mm and glue in an 8 mm sleeve (25 mm long, 8.3 mm bore), or drill to 14 mm and use a 10 mm sleeve (30 mm long, 10.3 mm bore). Six 0.3 mm crush ribs bite into the wood and leave channels for the glue, and the chamfered nose starts the sleeve straight in the hole.
