Replacing lead Keel bolts
The Keel bolts looked good, but when I went to check the torque, all but two twisted off with little effort. Kinda scary. Anyway, its a lead keel, probably has the studs casted in. I would like to replace, or add new bolts next to the failed ones with out fully removing the keel. I heard that some have used lag bolts. Has anyone tried anchor bolts? Like for concrete? Or, I wonder if setting a helicoil into the lead would be strong enough? Or maybe some other type of blind insert?
