My Train horn build, Nathan K5's

Main Your Horns & Installs
1

This is my install of Nathan K5HL on my 2007 F-150 screw.

I will be purchasing a turn key kit from realtrainhorns.net | Real Train Horns , I have already talked to the guys there and they helped me decide on a kit.
I will be installing a 8 1/2 gal air tank and two compressors, and I am planning on everything being installed under the truck. The K5s and air tank will be mounted where the spare tire goes and the two compressors will me mounted under the bead just in front of the rear axle on a bed cross member.

Tonight I got the horns ready to paint by taking them apart and masking off the manifold where the horns mount up, and I covered the Nathan serial number tag. I used Dupli-color Acetone to prep the surface and remove the dirt/ oil/ ect.

Taped all 5 horn mounting locations, the mounting plate, the serial number tag, and the allen head screws

Self etching primer, Acetone, and painters tape( tip: get the 1 1/2" tape and the 1/2" tape, and a X-ACTO knife)

Do notremove the rubber gasket on the horn, just tape over it, just be sure not to remove it with the tape later.

It was easier for me to tape the outside edge with small pieces, use a knife to remove the over hang then tape the center

Here is everything prepped, masked and ready for the self etching primer.

I then used 2 cans of the primer to apply about 3 solid coats of primer to all pieces.

Bells

Back plates, used tooth picks to plug the holes in the back.

Manifold

I left the diaphragms and cushions in there sets and wrapped them in shop rags so they would not get over spray on them.

I will be purchasing black gloss spray paint and silver spray paint. I am painting the inside of the bells silver while the outside will be black. I Have not decided if I will be putting a clear coat over it or not.

Next I used Dupli-color gloss black and Dupli-color Stainless Steel paint. Both covered well and I applied about 3 coats of each color.

I sanded the primer with 800 grit paper them went over them with a micro fiber cloth.

I ran a line of tape around the bell so I could paint the inside of them with the SS paint.

Once I had all the bells inside painted I placed them over the heater to speed up the drying process.

I them placed each bell up side down on a shop cloth so I could paint the outside black without taping up the inside of the bell.

Here are all the bells and the manifold drying

Here is a close up

Here are all the bells painted up and tape removed

Not perfect but I think they look good.

Trying to figure out how to make the lettering and numbers stand out on the horns. I really want them to be SS too.

They will be assembled tomorrow. I did not have blue loctite to put them together tonight.

Um…where did the horn get bought?

Why are you buying the kit from…isnt that a competitor’s company?

Open forum, yes. Just found it odd. Nice horns indeed!

I got the horns from a friend for a great price. I am not too worried about where I bought the kit from because is the economy today, you half to shop around. I would hope any business would respect that and keep there prices and service competitive.

I agree. I was just under the impression otherwise regarding posting here.

BTW, I see you’re mounting under the car but opted to paint the horns. And I see others painting their horns as well even though they are buried and not really visible.

Are you guys painting just for looks or to ‘preserve’ or protect the horns from the elements?

14

Grrrr…Someday!

15

what?

16

I painted mine to preserve and protect them, plus i wanted to do a detailed wright up

17

Very nice where is the 8 1/2 gallon going on the truck?

18

Just frustrated…dreaming of my first K5LAs…

I will be mounting the 8.5 gal tank beside the horns. I will place the horns about 5" off center of the truck where the spare tire goes, then cut the feet of the tank shorter if needed. The tank is 9" tall but with the mounting feet it’s 12 or 12.5. So I can cut 2.5-3" of mounting feet off if needed. The two compressors will be mounted to a bed cross member just in front of my axle and then I will run a air inlet line to behind my tail lights on both of them to keep from taking in water.
