You let us know, but my money says you can cook with it no problem. In fact, I will bet it was used for years like that.

You let us know, but my money says you can cook with it no problem. In fact, I will bet it was used for years like that. I agree my friend, I'm betting she'll work just fine. Given the nature of use regarding such a piece I'm betting with the indirect heat she'll be okay. For kicks to seal the crack I'm going to try a bearing solder paste. Low temp, final joint will be good to 650 degrees which is more than sufficient. I think brazing would introduce a higher failure rate given the amount of heat required. I'm not comfortable raising the surface temperature on a 200+ year old brittle piece of history to brazing temperatures. I do want to drill a small relief hole to stop any further cracking, coupled with the bearing solder that should fix her up for service. I've never done such a repair on a cast piece, let alone a piece this old... Having an understanding of cast irons makeup and tendencies I'm fairly confident in the repair option. |

Great find, I bet Hillary or Nancy will be missing it. You couldn't get the broom to go with it?

I wrapped them both up and overnighted them to your door. Figured you'd appreciate a wild ride from two experienced foxes.

Unbelievable difference... I actually feel somewhat ashamed at removing all those years of rust. Ole girl worked hard to aquire that patina. Anywho, once I repair the crack I'll season her up well which will hopefully darken the iron back up. I'm certain I now have removed the risk of lock jaw atleast.   img ru pSpence my apologies, you asked for measurements and I got all caught up in the day. She measures right about 9" across the top and necks down to about 8" then transitions into the belly which to my eye appears to be the same dimension as the top measurement. Coming in on height she is right about 7.5" and lastly the legs protrude from the casting about 1 3/4". |

I'm certain I now have removed the risk of lock jaw atleast. "Lock-jaw" is a result of the bacterium that causes Tetanus. Somehow lock-jaw became associated with rusty nails, but it is more the result of a deep puncture wound that inoculates the Tetanus bacterium (naturally present in the soil) into a favorable (oxygen poor) environment. |

Then we can throw that out the window! Good to know, honestly didn't know that. Why is it they want to stick you with a tetanus shot when you get cut by something questionable, almost always rusty? That's been my personal experiences and that injection is rather unpleasant. |

They want to stick you as a preventative measure and the shot is protective. Tetanus can kill you in a rather unpleasant way...

That's been my personal experiences and that injection is rather unpleasant. It isn't so much the rust itself. Puncture wounds are more likely to become infected than a cut or other abrasion. And if the metal was rusty, that would be a pretty good indicator that it wasn't well cared for and clean. Does seem odd that the 1st response to a puncture would is to give you another puncture wound. Hair of the dog.... ? |

Better safe than sorry, good enough as I bet it certainly isn't an enjoyable experience.

No, my understanding it is pretty terrible.

Tetanus is unlike many other bacteria in that the disease that it provokes is not so much an infection but an intoxication with a microbe-made poison. Embedded soundly in a enclosed and airless wound, C. tetani pumps out tetanospasmin toxin, which acts on the central nervous system much like the pesticide and poison strychnine. Tetanospasmin is one of the most potent toxins in the world and works by irreversibly blocking the release of inhibitory neurotransmitters that work on the muscles, interfering with the natural rhythm of action and inaction of axonal nerve firing. The case-fatality ratio in the United States was 91% in 1947, 21-31% from 1982 to 1990, 11% from 1995 to 1997, and 18% from 1998 to 2000. Current statistics indicate that mortality in mild and moderate tetanus is approximately 6%; for severe tetanus, it may be as high as 60%. Mortality in the United States resulting from generalized tetanus is 30% overall, 52% in patients older than 60 years, and 13% in patients younger than 60 years. Mortality is substantially higher for people older than 60 years (40%) than for those aged 20-59 years (8%). From 1998 to 2000, 75% of the deaths in the United States were in patients older than 60 years Tetanus causing Clostridium tetani bacteria thrives in an anaerobic environment. As iron oxidizes (RUST), it eats up atmospheric oxygen, creating a low-oxygen environment for the bacteria to grow. |

Prepped the area this afternoon. I was hesitant on using my small Swiss files I reserve exclusively for use on finishing and tuning locks, but I made an acceptance of the rule. I first drilled a small relief hole to prevent any further issues of the crack. Then progressed with my files to widen the crack to allow the solder to flow efficiently. I chose to fix the crack internally as it appeared to be the best option. Cleaned the area thoroughly with alcohol and a wire brush. She's now in the oven heating to limit thermal shock once I apply heat. Will report back in soon on success or failure. Solder I'm using is food safe so that won't be an issue.  Success, worked exceptionally well. Had to approach from several angles but flowed and set as I anticipated. She's now slowly cooling then I'll blend everything down.  |

I have had some success with having cast pieces welded that were small enough to fit into a furnace & heating (a lot) before welding. Neither inexpensive nor a guarantee of working. Sorry about the crack.

I have had some success with having cast pieces welded that were small enough to fit into a furnace & heating (a lot) before welding. Neither inexpensive nor a guarantee of working. Sorry about the crack. I'm a certified welder by trade, actually had to renew my cert this afternoon. I was going to give it a go with a special TIG rod but heating up 270+ year old cast iron just didn't sit well with me. Unfortunately it's make-up and reputation in repairing does follow suit when your dealing with the high temperatures required to fuse both the filler and base iron. Not impossible by any means but as you already mentioned no guarantee of success. The solder joint has surpassed my expectations so I'm very happy with the results. Between the two repairs and risk mitigation it was the winner. I'd expect the joint will hold up for decades now with care. She has character as well! I'd like to think my repair would have been a very logical one of the period if the situation arose. |
