Has anyone tried rebuilding a new the centerboard out of fiberglass and some lead weight
inside?

tartan27plee,
There was a discussion thread via the messages about centerboard replacement about a month or so ago. I am not sure if you can search the emails to find the feedback or if you just have to plod through the entire postings. One poster took a magnet or compass to his/her old board and mapped out where there was metal framing/support inside. It seemed as if the C/B was designed to break away if a rough grounding occurred. I am not sure if that was from the original S&S design but it seems to make some sense; let the C/B break but save the C/B trunk from catastrophic failure if a fully metal or steel C/B were used.
The C/B on our boat seems to be in good shape but I can't confirm the break away fabrication method as I was only able to paint it this season while the boat was up in slings prior to launch this spring.
Good luck with this project and I am sure it can be done as you suggested. I am just unsure about the working loads of the materials involved.
I also go by the name of Caleb Davison as well as quotidian01 @ yahoo

I am building a Westsystem epoxy glass laid up cboard for #408, 1969.
The core will have 105# of precast lead, instead of the two steel
plates in the '60s &'70s originals. Rather than the two outer skins
of heavy roven woving filled with just polyester resin, the cb is all
hand laid glass cloth in a female mold encasing the lead. The orig.
bronze pivot casting is all that will remain from the old board and
is of good design. A reinforced s/s pendent cable attachment hole is
bonded in the build up. West barrier coating & bottom paint complete
the system. pswift@...
