Horn Reassembly
« on: October 07, 2019, 12:52:17 »
I had taken my larger horn apart to clean it up and paint it and I am now reassembling it.  There had been what appears to be a paper gasket between the back housing and the diaphragm.  I was going to make something up, and maybe coat it with vaseline or grease.  I considered a small bead of silicon but I don't want to inadvertently dampen it.  Any similar experience with these horns?

I just did this job and used this material for the gaskets.  You can thank the Horn God 😈(66andblue) for the tip🤣

You can just use some sort of simple semi adhesive to keep them in place. I think I used a glue stick.

A well stocked artist's supply store will carry small razor blades that fit into a compass; a compass being, for those that may have forgotten, a draftsman's tool for making circles. As I was a graphic designer by initial education I have a fine set of Kern (Swiss) compasses, and the small razors that substitute for the normal [pencil] lead that goes into the compass. Today, there are also a number of low cost circle cutters available.

Using these two items, I cut new gaskets and punched (with a small hold punch) holes in them for the screws, and they were flawless reproductions.

Of course you can cut the stuff with a scissors, and punch holes with pointy things, and it will work. I did not use any gasket sealant.

Just to add a tip to Michael's suggestion, a single hole punch (see link below for a sample photo) comes in real handy for creating fastener holes when making your own gaskets.
