Do I need to start casting lead bricks to sell to you micro folks with keel anxiety? Cast them the correct thickness, with
interlocking, or possibly rough sides. You non-metal melting boat builders could then just epoxy them into your keel.

Not bad! Maybe you quit too soon, though: Why not twin bilge keels, and
pump the mercury into the windward keel? With a little easily-added tubing,
you'd also have a thermometer giving you accurate water temperature!

Not to advocate putting a concrete keel on a Micro, but it should be
pointed out that concrete has a history of being used for external
ballast keels on amateur built boats. Sam Rabl shows it in his classic
book _Boatbuilding in Your Own Backyard_, and George Buehler (who could
be considered the ideological descendent of Rabl, as they both stress
low tech, low budget traditional approaches) advocates it in his book
_Buehler's Backyard Boatbuilding_. Buehler's experiences with it
indicate that it is quite strong and durable with the proper mix of
concrete.
