I was going to pull the keel anyway to inspect/replace the keel bolts because of the amount of rust at the hull joint. Thanks Glenn for that tip. I was planning on going the wheel weight route for cost reasons. I'll also keep your points in mind for why I shouldn't just go out and buy scrap lead. JJ I would still go for at least 50% wheel weights. As I said pure lead is very soft and if the external keel is bolted on, the normal movement will wallow out the lead around the bolts/washers and cause the keel/hull joint to open. 50% wheel weight lead mixed with miscellaneous scrap will insure you get 1.5 to 2% antimony and harden it up enough to prevent that.
