      I appreciate your concerns. How much lead exposure does one face
      casting outside? How much is sufficient to cause lead poisoning?
      Casting centerboard weights isn't something I plan to hake a habit of.

      I'm not sure how well wheel weights would work in this situation,
      given their large, uneven size, which would leave a lot of empty space
      to fill with epoxy or other resin. I think lead shot would work
      perfectly well, though, as I suspect I have more lead than I need cast
      in place, judging by the weight of the centerboard & rudder.

      If I have occasion to weight another centerboard, I'll probably use
      that method rather than casting.

      Thanks for the helpful advice on respirators.
