Original horns
« on: October 23, 2021, 08:02:40 AM »
I have the original horns for my '68 but neither work. Is it worth having them repaired/rebuilt, and who does that?

Ditto for my '65. I had to install cheap aftermarket ones just to pass the safety inspection when I imported the car into Canada several years ago. I couldn't find anyone who would repair/restore the originals at the time.

I have had good luck by connecting battery and ground (while on bench) and TAPPING with plastic mallet. Not much to lose by trying……..worked for me.

There are people who restore horns but the cost is hundreds of dollars each to do so. With so many still around from donor cars you can see the cost advantage of finding another working used one. There are kits to restore your own however it is my experience that if you can't get the horns to work with out tearing them apart the kits which only include a gasket and new rivets will not do any better.

How heavy of a mallet? :o

The 65 and early 66 are ink stamped dated so another donor can be made to look like it was born with the car.   A later year version original horn to a given car that is date stamped correct  may be worth the expense of rebuild. Of course date stamps are not considered in DIV II or Trailer concours.

I use a rubber or wooden mallet. Not about the weight but how hard you hit it.

Yep... and a small squirt of wd-40 will help. There is also a n adjusting nut that can be moved a bit to help the process.

Well see, the weight of the hammer IS about the volume of impact provided.

How hard do you hit it with what weight hammer = critical mass is the issue.

Thanks Bob - makes sense! I think I'll try the hammer method on the originals first & go the donor car route as a plan B!

I'll try the hammer system. With the absence of scientific data as to how much force to apply, I'll have to use the empirical method. When the housing cracks, I should stop.
