Unfortunately I'm in Maryland, the freight costs would probably make the total
cost prohibitive. Otherwise I would be very interested. In answering questions on several other replies: The point about trim is valid but the penciled in changes to the factory blueprints have the weight distribution (it specifies what weight to be put where) pretty much matches that of the external ballast keel, and several other owners who removed the ballast to lighten the boat for afternoon racing reported that the boat was excessively tender but trim was OK. I'm wondering if the design was originally drawn up for lead and the yard substituted iron, and went back to the designer after complaints for advice. The factory blueprints don't spec the weight of the external ballast, but the internal ballast is detailed. The boat was built by Werf Gusto in Holland in 1961 and designed by Bill Tripp. The blueprints are in Dutch but the internal ballast is penciled in English. The shape of the external ballast is about 4' or so long, around 8" high, and 8" wide with a 1" centerboard slot making it look like a stretched 'U', so cautions about alloys for fins (with their high bending loads) I don't think would apply. I was going to pull the keel anyway to inspect/replace the keel bolts because of the amount of rust at the hull joint. To drain the lead from the melting pot I was thinking about something I read about by Larry Pardey. He used a cast iron bathtub and had a plumbing pipe elbow welded to the drain. Screwed into the elbow was an 'L' shaped piece of water pipe. He used a chain to lower one end of the 'L' to start the pour, and raised it to stop it, with the 'L' rotating by the threads at the elbow. His book about classic boat construction is one of the few references I found.

If you don't mind what did you use to melt the lead? snip I don't know where you are located, but I no longer need my melting equipment including ingot molds that produce 30 # pigs. Have 2, 500,000 BTU propane burners and a melting pot that holds about 900 lbs. If interested, I'm in Los Angeles. Lew James Johnson remove the "dot" from after sail in email address to reply |
