Removing air horns and adding train horn

Please do it , china, so I can shoot turtle AND his annoying truck...

 

couldnt you just imagine trying to sleep next to my truck if i did it on a windy night lmao

 

I can't imagine a scenario where I would be sleeping by yer truck

 

I'm happy with those plastic Buell horns. Sounds close enough to a real train that people slam on the brakes when I lay it on by a RR X-ing! Can't see paying over a grand for a toy like that.

 

I had a pair of air horns from a P&H mining shovel kicking around. No idea where they ended up. Those would have been sweet to mount under the hood somewhere.

 

This thread has went off the rails

 

I've seriously thought about replacing the city horn in my company truck with one that does something funny like play s dixie or sounds ridiculous. my truck has both a city and air horn and the change I made would only require unplugging and unbolting and swapping back to the stock horn.

 

Rank,
The correct way would be to remove the horns, and weld the holes, and grind. But Not everyone has access or the skills to weld aluminium. This is the way I have done holes many times, and works great.

Remove your air horns. Take Hammer and beat down the metal around the holes.You want a very large dimple. Maybe 2 inches around 1/4 to 3/8 inch deep where bolt holes were. Use your DA with 40 grit paper and sand so everything is clean and very rough. Next you will want to use a product called long and strong or something similar. This is basically a fiber reinforced filler. Stuff sands well, but be warned, you want to spread fairly level. Very hard, and excellent adhesion. You will rip your roof before this stuff will break loose or ever leak. I recommend sanding with the DA, finishing with 80 Grit. Next just use regular body filler, and sand with 220. I highly recommend staying away from glazes on trucks for feathering. A little more time consuming to use body filler as a glaze, but it will not crack like glaze will. Just use glaze for a pinhole here or there. Primer and Paint.

You will need to remove your headliner form your truck when doing this Remove the airlines from the horns. Reroute through firewall to where you want to mount your train horn. I have never seen a ticket for only having a train horn. I prefer to run line from the air horn valve in the truck, to the horn itself, instead of an electric over air solenoid. Much more dependable, but just me. Hope this helps.

 

Thanks Ridin but it's too late. It's in primer and getting metallic burgundy tomorrow.

I used JB weld to bond 1/16" aluminum patches on the inside and outside of the roof. When it's done folks will think I'm a Seminole fan

 

why so loud ? air horns aren't enough ?
