keel bolts
 
Hi
I would like to know if anyone knows were to get Galvanized keel bolts made for my 1951 John Alden ketch,

It would help if you said what diameter, length and thread pitch the bolts were.

Hi
All I know are they are 1 inch galvanized bolts with a tapered head, The plans I have dont give any more detail and they are in German, Im looking for a reputable machine shop that once they are removed I can send them too and have new ones made.

Where are you located? If you're in Tahiti, the suggestions I have won't do you much good. :D One machine shop that I'd highly recommend is the Pungo Machine Company in Pungo, NC. They were very helpful when I had to re-build a sail drive leg on a recent delivery trip. :D

If the plans are in German the boat may have been built in Holland or Germany and bolts may be metric. Does not matter as any good machine shop anywhere in the world can replicate if given a bolt or drawing of same. You might consider using bronze as a material so you eliminate galvinizing.

One issue with going with bronze, it is weaker and more fatigue prone than steel IIRC.

keel bolts
 
Thanks for the info, plans are in German but only give diameter, I will have to remove to get the exact length, She has a cast iron keel so I will be sticking with Galvanized bolts

I live in Tahiti and we have some good machine shops but no galvanizing facilities, so looks like a State side project.Do you have an email address for Pungo machine company?

You might consider using replacing the bolts with monel, which may be cheaper and easier and be a far superior metal than trying to get a machine shop in the States to produce the bolts and galvanize them. Also New Zealand and Australia may be closer and cheaper as well.

Here's their contact info, but I'd second what Jeff said about NZ and Australia possibly being closer and cheaper.
