painting cast Iron...
I'm trying to find a way to turn cast Iron into gold, and I have about
2 weeks to do it! I am running a cooking competition for a Bluegrass festival in KY and I need to get a cast Iron dinner bell painted (preferably gold) for the prize. This is somthing that is going to be used year after year, so it needs to be fairly good at retaining its paint, but i don't want to fudge upt he acoustics too much. I know I must stay away from oil based paints, can anyone give me an idea? should I just say to hell with it and look for a (much more expensive) brass bell? or can this idea be salvaged? any advice would be great! in haste... distortedreality |

BTW, does this bell have to ring (like a bell?) Cast iron has a lot of damping, so it will probably not make a clear, long ringing sound. Also, what's wrong with oil-based paint? |

I would try painting it with that shiny gold spray paint they sell at the
auto parts stores. I dont think the bell will suffer too much from painting. The reason I say this is I saw a guy that made really big chimes out of old welding gas bottles. Those suckers rang like crazy and they still had the original paint on them. -- Roger Shoaf If knowledge is power, and power corrupts, what does this say about the Congress? wrote in message oups.com...

I'd just primer and paint it. If you want it to look good putty, high build
primer, sand, repeat, then final coat. "Roger Shoaf" wrote in message ... I would try painting it with that shiny gold spray paint they sell at the auto parts stores.

But if one wants something easier but still looking good, you just grind off the high spots of the bell, prime it with the glue and put the leafs on. No big deal.

A large concrete wall was sized and covered with gold leaf in Symphony Hall in Salt Lake City, Utah. My wife and I did the cleanup afterwards, and recovered a couple ounces of gold. If concrete can be made to look good, a cast iron bell wouldn't be much of a challenge. Only if you desire it to look machined would it be much of a chore. Fact is, gold leaf applied to slightly irregular surfaces has considerably more character than it does on perfectly flat surfaces. Harold |

What about the fake gold leaf they sell at craft stores. Cheaper and
would probably do the job. Karl |

ACK Fact is, gold leaf applied to slightly irregular surfaces has considerably more character than it does on perfectly flat surfaces. ACK. That's what I meant with "still looking good". Doing it the easy way makes it look "antique". Nick -- The kit-DRO Available now in USA / Canada http://www.yadro.de ...|....|....|....|....|....|....|.. |

I've done that too, with a 122 cu ft oxy bottle. Plasma-cut the bottom off, ground it smooth, welded a ring on the top to hang it. Tawk about sustain! Once struck, it rings for a very long time!

Gray iron = Lower cost than bell metal (bronze) but sound not as good for
reasons mentioned by Leo below. Ductile iron = excellent choice. CS Bell Foundry in Hillsboro Ohio started out making gray iron bells but they had their own composition to give the bells a good tone. Ductile iron was invented / discovered in the late 1940's and patents did not run out until the early 60's. At some point CS Bell Foundry began using ductile iron. Ductile iron would be an excellent choice for a bell because it is somewhat closer to steel compared in damping capacity compared to gray iron. The thing is, once the bell is tolled the gray iron would reduce the ring time, i.e. the vibrating bell lip would vibrate a shorter time so the tone would have less harmonic vibrations and will not be as "rich" in sound quality. I would think with good surface prep the iron could be paints but I would keep it to minimum thickness to prevent the paint from affecting the tone. Mark "Leo Lichtman" wrote in message ...

There is no burnishing to speak of, so the gold leaf has a very pleasing texture. The use of cotton made recovery of values much easier for me. Interesting that agate is used. Likely because of its hardness? Harold |

Might also have to do with affinity (or lack of) to gold. But I'm far away from being a chemist.
