Qué cubre este vídeo
The crew of the 10-year rebuild project boat *BrewPeg* performs maintenance on the rudder pintle bearing and propeller while the vessel is hauled out. After identifying that the rudder pintle bearing lacked sufficient clearance, causing it to bind, the team uses a drill-mounted sanding wheel to ream the plastic bushing.7:04 They target a clearance of 18 to 28 thousandths of an inch, monitoring the internal diameter with an internal micrometer.6:59 Because the plastic material expands when heated by friction, the team alternates between sanding and cooling periods to ensure accurate measurements.7:23 They successfully achieve a final clearance of 21 to 24 thousandths of an inch.17:59 Additionally, the crew cleans the propeller and keel cooling pipes using emery cloth and a battery-powered grinder with a purple abrasive disc to prepare the surfaces for new antifouling paint.2:17 The work is complicated by frequent rain squalls and a temporary failure of the air compressor’s alternator.11:50
