Just so there is no misunderstanding those are not my drawings but ones I found and posted...

If the person that did do the drawings sees this I would love to give them credit,

I just noticed that little PayPal "Donate" button on Sumner's Home Page. Say no more!

Know what I mean?

I have fully considered this also and determined its not worth the time, and the keel is beyond repair. We do metal work and this thing has cancer once its really bad theirs no going back. if i could i would but cast iron is just not a good material to work with. not sure if you managed to see the photos over on the other site but worth a look if you want to know what i mean. I am going to most likely sand the replacement down and wrap it in epoxy and glass if i get fancy, otherwise it will just get a solid coat of bottom paint.


Just on the off chance that someone may find themselves in a similar, if perhaps less dire and
irrevocable battle with rust, here's a cheapo solution in the chemical sense of the word that might make it all better: Get yourself some molasses. That's right, molasses. "Black strap" style is best, but most any molasses will do. Mix up a solution of one part molasses to about 9 parts water and give that rusty doodad a bath for a week or two. It seems that molasses contains something called "chelating agents" that latch onto and carry away those oxides. It costs little and works amazingly well. Finally found that wrench in the bilge, and she's looking like she came off the Titanic? Give her a molasses bath. You'll be amazed.

I've also got an Amphicar, one of those cockeyed amphibious "boat-cars" from the '60s, and we're locked in eternal battle with the laws of physics AND chemistry just to keep swimming. So, I actually keep a broken old deep fryer around for this sort of oxide-gobbling fun. Obviously, a swing keel would need a slightly bigger tub. Say a plastic tarp laid into a wooden frame, but it'll do the trick. Just don't try the resulting spew on your waffles, unless you're suffering a serious iron deficiency.

Seriously, raid Grandma's pantry and try it out! Grab that Wisk laundry detergent while you're at it. It's a great boat cleaner.

Funny you'd mention "soda", because back in the day folks would also use Coca-Cola to the same rust-removal effect, if rather less effectively than molasses. Apparently "the pause that refreshes" was also believed by some people to be an effective post-coital birth control method. These people are called "parents."

As for the molasses bath treatment, fear not that it might dissolve any clean metal from whatever's being soaked. The molasses only carries away the oxides, or rusty bits, leaving the actual unsullied metal alone.

Not that a vigorously-shaken classic six ounce bottle treatment of the lady parts is an entirely woeful affair, mind you, as explicated musically during the practice's '60s heyday by the Fugs, New York Greenwich Village's very own superband, as a quick YouTube search of "Fugs Coca Cola" will rather saltily and shockingly illustrate (NSFW).
