The Ford Barn

Kevin in NJ · 09-14-2014, 04:33 PM

Just because I am restoring a Stewart Warner horn for my car. I have a limited selection of horns. A few Sparton horns, an early Ames for Ford script and 2 SW's.

Truthfully the Sparton would be easier to restore. No real pitting, but I do not like that repro tag.

It turns out the SW horns are alike, but different.

One has a light SW script on the bell and the motor plate. The other has a deeper script on the bell only. The screen was different between the two. One was rolled over more on the edge.

There were some constuction differences between the bells too.

What up with all the horn bracket. All are a bit different. I have 3 that I have found so far. I think have a couple more in the piles. Anyone know what would be correct for a SW?

I have looked at the JS and into the back issues of the 2 magazines. Not much information on subtle differences.

The above info is not critical for my restoration. I am going for a nice working horn. If I know what is more correct and I can go that way I will.
I just noticed some stuff and thought I would bring it up here.

Thanks.

Be careful - The SW motor turns opposite the other makes hence that special left hand thread and special nut on the end of the motor armature - it's real easy to twist off if you unknowingly assume a regular right hand thread like the other brands.

I personally prefer the SW horn - the best "a-ooo-gah" out of the several different brands that I have.

Yes, the S/W horn seems to be the preferred horn for fine-point simply because they seem to 'Ahooga' better without the engine running and as Kevin states, the original tag and the repro tag differ enough to get a point deduction.

FWIW I learned about the left hand thread the hard way.

Not a problem, I own a little SouthBend 9" lathe. I made a special adapter with left hand threads (first time I did that). Found I could chuck the armature up in the lathe and have it centered so I could bore into the end of the shaft. I tapped it and then screwed in my adapter with super thread lock glue.

Was not so bad to fix in the end.
