A number of years ago I did a summer work term with a Toronto area Water Works Dept. We got to spend a lot of time observing various projects in the community as we were students. (Yup, I was one of the 8 gov't workers standing near the work that was being done but not really doing anything)
Anyway, one day we were at the scene of a watermain break and once they had the water shut off and the break located and dug up, they put a giant collar around the old cast iron pipe and then welded a giant piece of zinc (3 feet long by 10 inches in diameter) to the pipe to act as a sacrificial anode. This was to prevent further oxidation and hence weakening of the pipe. I can access zinc pot draw samples from a local galvanized steel manufacturer. I have a zinc sample now that is 3 inches in diameter and 5 inches long. If I were to bolt this to the frame of my 914, would it help to reduce futher oxidation in the same way that the various zinc primers etc. work? |

I thought that a sacrificial anode only works in water and in the presence of electrical flow. Boats in a harbor use zinc as a sacrificial anode because of the high alkalinity of salt water and stray current from boats.
