"Sound My Own Horn"

     When I bought the 32 it came with various parts which were not installed on the car.  Two of those parts are the chrome horns that mount on the headlamp bar.  I really like the look that it adds to the coupe.  Both of the horns had several small dents in the bugle portion of the horn.  I was able to remove these to my satisfaction with the use of several different sized wooden dowels.  When I took one of the horns apart I discovered that it was missing the sounding diaphragm and it had also been cut and shortened about 3/4 of an inch.
     The search was on, after about 2 weeks I located one on CL (craigslist) in Penn., I bought it and had it shipped to me.  It too had several small dents which I was told about prior to buying, that's alright, what's life without challenges?  I removed the dents, it was complete, and after polishing and adjusting, I was able to "Sound My Own Horn" X2  They are going to look great on the car!
     In my opinion the Internet is one of the greatest resources a person can have.  I hadn't really worked on horns before and I really didn't have a good working knowledge of the way that they operate.  I found a company (Vintage Noise), located in Australia, they had copies of the original Delco-Remy service manual for the horn.  Vintage Noise makes and sells brass horns and horn bulbs for antique cars, check out their website at www.vintagenoise.com.  The horns on the 32 and even modern horns are an  electro-magnetic device that vibrates by interrupting the magnetic coils circuit many times a second.  This causes the sounding diaphragm to hit the core of the magnet making a tapping sound that we hear coming from the horn.  If properly tuned that tapping is happening so fast that we do not hear any interruption in the noise being emitted.

One of several dents to be removed.

By using this large dowel, I can push and rub from the inside to remove the dents.

Almost gone!

Dent removed and horn polished.

Final assembly, adjusting and testing, BEEEP--BEEEP!

"MAKING DO"-----"TIME AND MONEY"

     Sometimes you don't have any other option than "MAKING DO" with the materials that you have on hand.
Cross drilling and tapping.

Test fitting the threads, one more to go!

Welded, grinding done, and polished, where's the tank?
Other times it is the lesser of two evils, by that I am referring to "TIME AND MONEY".  For myself "TIME" is usually more available than "MONEY"  and I enjoy the challenge of creating what I need.  In order to expedite things I will sometimes opt to make an item that may not be readily available at the moment.  The fuel tank strap TEE BOLTS were just such an item.  If I ordered them it would be at least two weeks, they were on back order.  I decided to use two long threaded bolts and two larger bolts to fabricate the needed TEE BOLTS.  I cut off the shaft of the large bolt, located center, drilled and tapped it to receive the smaller threaded section.  I then assembled the two, welded, ground and polished the bolt.   As you can see from the pictures they turned out fairly well.  Now if I can get my fuel tank back from powder coating, that part of the job can proceed.
