Rebuilding horns from a 71/240z

[grannyknot]

The paper gaskets are too damaged to reuse so I'm wondering if I can use a thin layer of liquid gasket instead of the paper?

The sealer would keep the horn from rusting up again the way the paper gaskets allowed but wondering liquid gasket might damped the vibrations when the horn is sounding off.

Any experience either way?

Some suggestions for new gaskets:

- thin (1/32") , closed-cell neoprene sheet (Michael's craft store)

- the material used in those stretchy exercise bands (Canadian Tire - sporting goods section)

- lid from a margarine tub (soft polyethylene)

I really don't think there'll be an issue with vibration damping, but at least it'll be easy to go back to paper if there is.  If you want to try sealant instead, how about strippable window sealant (DAP product, available at CTC).

I just cut new ones from paper gasket sheet 🙂

What I did for the paper gasket was take some card stock and cut it to the appropriate diameters. After punching the holes, I sprayed both sides with a few layers of plasti-dip.

But the original gaskets are the thinnest paper, that's why I was thinking liquid gasket, if the gasket thickness is too thick won't that change the sound of the horns?

Steve, did the card stock change the sound of the horn in any way? Maybe I'm being too anal and it just doesn't matter.

The gasket didn't change the horn sound that I could tell.
