Yes, an iron board could be done from a wood pattern, but it would be pretty heavy, which wouldn't hurt performance except in a drifter, but you'd need to come up with a better way to lift it, like a winch and a wire. If this is done, the wood pattern needs to be a bit larger to account for the shrinkage of the iron. Seems like it's about 3 or 4 %, but check with the foundry. ________________________________ From: Lawrence Winiarski <lawrence_winiarski@yahoo.com> Sent: Sunday, February 2, 2025 2:22 PM To: montgomery_boats@mailman.xmission.com <montgomery_boats@mailman.xmission.com>; jerry montgomery <jmbn1@outlook.com> Subject: Re: M_Boats: Re: New to email list, looking for a replacement centerboard You got me thinking about the idea of a cast iron centerboard.....Any other thoughts about this? Would someone commercially be able to cast this from a wood plug better, or just make a wax version better?

If all fails, I think you could make a decent on out of aluminum plate. Double check this but I think the boards were 1 1/4". I don't think an accurate drawing of the board exists anymore, but you could determine the size by taking some close measurements of the trunk, using a yardstick. If you're a woodworker you could make one of wood, with a lead slug at the tip, then heavily glassing it, and bushing the pivot hole. Err on the side of too thin because you can always use bushings on both sides at the pivot. Another good way would be to make a pattern of wood, then have it cast in iron. Good luck! ________________________________ From: Lawrence Winiarski via montgomery_boats <montgomery_boats@mailman.xmission.com> Sent: Friday, January 31, 2025 3:05 PM To: montgomery_boats@mailman.xmission.com <montgomery_boats@mailman.xmission.com> Cc: Lawrence Winiarski <lawrence_winiarski@yahoo.com> Subject: M_Boats: Re: New to email list, looking for a replacement centerboard Sounds bad. Dumb question: What about the rope that you use to raise and lower it? Did that suddenly come loose too? If it was me, I'd exhaust all methods to find it at the bottom first. Spirit lake is deep, but not that deep. Maybe try and recover it. Google says around 40'.

It can get pretty gusty here and my "Penelope" can get rocked on the dock pretty aggressively. The centerboard front pin had worked its way loose (unknown at the time to me) and during a sail last season I notice a bump... then no centerboard. My board is lost in the deep and I am looking for a replacement. Does anyone know of a source or specs for the size, shape etc... To have a new one made? -Don
