Replacing 40 year old keel bolts: Drilling, tapping and lessons learned.

40 year old keel bolts finally replaced and keel confidence will be restored! From snapped bolts to tapping and drilling new ones using a mag drill, and a tap set. Credit to all fellow Copland Harrier owners who have passed on their experience to me regarding this job. Huge shout out to my dad for helping me and for the father son bonding! Good times! Back out on the ocean soon! Links to the tap set here; No affiliation: https://www.rennietool.co.uk/products...
