OT, air horns

How are they powered ? I thought horns that big required onboard air or 24V supply at least ?

I used an air compressor from an 81 Wing's suspension, 2 old propane torch tanks as air tanks, a solonoid valve, a 140 PSI shut-off for air bag suspension. I didn't lose any cargo capacity as it's all outside of the bags. I get about 5 seconds continuous blast (an eternity) or about 7 short hoots in succession, and then about 5 minutes for refill. I will be looking to scrounge a better compressor, but don't want to use all my charging capacity. I have an area above the center stand where i can install another small tank, but am looking for something to fill the shape. The system could all be removed in 20 minutes If i get tired of it (not likely) and when I install an 81 Wing's rear swing arm and final drive on this 76 Wing in a few weeks, I will be able to use the 81's air shock system without the usual welding of different lower ends to the shocks. This combo will give me a higher gear ratio for better mileage, and lengthen the wheelbase 2.5 inches. Tomorrow I am leaving on a ride for the weekend, so i will be able to compare my mileage with that of my trip 2 weeks ago and see what kind of change there is. I could follow aerodynamic practice and put a simple spike in front of each hooter to split the airflow, but the numbers will tell me if it's worth the effort.

And yet you insist no beer was involved.....???

That is totally wild, must have been good drugs instead.... ;-)

Just so you know, using train horns on motor vehicles is illegal in some jurisdictions, like Miami.

That is high quality funny. n.

I'll take my chances, and lay off in town. At least i have good mufflers on my bike, so i only annoy people at will, instead of everyone ,all the time.

Beautiful! I know what those horns sound like, and I'll rolling around just thinking of that sound coming from a bike!

I'd like to do this on my Jeep!

I noticed that BEER wasn't involved. Vodka? run? shrooms? weed?

And very red... for someone from Kaliforia.

OK this is one of the coolest thing I've seen today Back when I road street bikes I always wanted a LOUD horn to wake up the idiots that always seem to cut mr off, make left turns two feet in front of you etc, etc, etc.

Toot those beauties and they'd $h!t their pants, which is only fair IMO because I had to change mine more than once.

Where can I get some? I have 5 gallons of air tanks with a York hooked to them. My stock horn doesn't function for some reason, or should I say it trys to function all the time. I would love to put some of these on my Jeep.

What does it take to make an old propane tank to work with air lines? I've been thinking about doing that to add some capacity to my ARB system. But I haven't really researched it yet. TrailMarker.

Why not use propane, and light it as you blow the horn?

A tuned flamethrower!

That's wild! Thanks for all the links and planting new crazy ideas into my head.

They aren't very large, probably not useful on a Jeep. You could hold a lot more air in your roll cage. I did it the "fun" way. After leaving a bernz torch on for a day to be sure pressure was gone, i clamped the bottle in the drill vise, set up a 3/8 inch drill bit, set a large piece of 1 inch plywood in front of it, and used a rope to operate the drill from behind a toolbox. I did 3 bottles, no boom. I then brazed a steel 1/8 pipe nipple to them. I filled them with water to displace the gas, emptied them, and then filled them with argon before brazing, again using heavy plywood, full faceshield, gloves, etc, after first waving a flame at them from behind a large object to see what happened. Freon cyls from an ac shop or appliance repair should be large enough for you, but they are also thin and may rust out in a few years.

Ebay, for about $100 per tube. I got mine for a lot less, they needed welding. I recommend that you have the receipt handy, a railroad man I know tells me that the railroad loses a lot of horns to thieves, and will assume that yours are stolen and call the law if they see them. I passed up on some perfectly good chances to make people fall off of ladders, etc today. It's a lot like walking around with a shotgun, you shouldn't fire it without a good reason. The joke isn't funny if it can cause injury, damage, or harasses livestock. This morning I was on a road that crosses tracks just before a traffic light. 2 cars were stopped clear, and the moron in the third car stopped ON the tracks in an area where the trains go by at 70 MPH. They will probably remember me for a while. I gave a few long blasts a bit later in the day, over mile outside of Coulterville, a historical gold mining town that once had rails, while coming down a long hill. The guys doing a cowboy gunfight in the street gave me a round of applause as I went by. Too fun.

Is not that hard, either an electric or vacuum compressor capable of a litre or so of air at 100+ psi. A traditional diesel truck is usually two horns, american style diesel 3 of them. If you have an MGB, the electric compressor is recommended as the old Hadley vacuum compressor will lean out your engine enough to almost kill it on every stroke at idle. Lotsa fun...particularly if some yoyo is obviously not looking and starts to pull out in front of your very small sports car and all of a sudden tries to figure out where the semi came from.

Although I've never used this particular brandset, several samples here, including the cannonball which sounds much like the old northern diesel.
