Horn Rebuild Kit
Any one know where I get the rivets and gaskets for the horn. Zip does not carry the simple rebuild kit anymore, and I don't want to pay for the metal diaphragms.

Re: Horn Rebuild Kit (RMS73)
Paragon will sell you the rivets and gaskets by themself. They do not advertize it, but they will. The rivets are about $.20 each, but I make my own gaskets now as the last few that I bought had shrunk and did not fit. I agree that the replacment diaphrams are junk! They are too thick and do not make as loud a sound as originals. I re-use originals whenever possible.

Re: Horn Rebuild Kit (GDaina)
when the horn doesn't sound, that means the diaphram gas gone south?

Re: Horn Rebuild Kit (GDaina)
If it doesn't "honk", could be several things. The diaphragm is only one of those items. Could be electrical...the coil/magnets, etc. Could be rust/dirt. The replacement diaphragms for both high and low are now "repro'ed" with the same thickness, whereas original diaphragms used one thickness for low, and a thinner for high. I think lows were .020 and highs were .015 inch. That's why often high note horns won't work with the repro diaphragms.
There's a real science to rebuilding these, as you not only have the mechanical and electrical elements, but you also have the "tuning" element. The rivets must be set like you're tuning a snare drum...with the same "tightness". Otherwise, the diaphragm won't vibrate correctly. Two of my friends, and Mason Dixon Chapter NCRS members have a side business rebuilding horns. They use original parts whenever possible. They are always buying swap meet horns to pirate for original parts. They had the rivets custom made and use a special press to install them. It's a labor intensive job. I've watched them do it.

To George:
Interesting comment about the diaphragm being bad and equating it to the south. Down south we would have said it went north.

Re: Horn Rebuild Kit (RMS73)
Dennis Portka has been rebuilding Corvette horns for about 25 years, and it takes him about 8 hours per horn; very tedious, more "art" than "science" :thumbs:
