Are there any good quality 12v tyre pump compressors about?
In my experience they all seem too tinny so was just wondering if anyone made a good one at some stage. Happy with second hand.
It's for pressurising the tank for the train horns which arrr going on the boat so it wants to go up to about 130psi ideally.
Using a car type valve so looking for a portable 12v tyre pump.
No hellfrauds junk. And not looking for garage equipment. Just quality in a small package .

Will of course need some manipulation to make it suitable. |

The concept isn't nearly complicated enough. I suggest a 2000w inverter linked to a industrial compressor. Or how about an SR2 which powers up a separate compressor originally intended to start a tank engine like in a Centurion or a Leopard. It would only take about ten minutes to produce enough compressed air so you can alert the other vessel to the immediate danger.

Couldn't your 'gadget man' at Mi6 knock you up something suitable?
After all, he did a fine job with the Garrotte Watch, the dagger shoes, the underwater jetpack and numerous laser pens, a 12v compressor should be a piece o piss for him!

It's just a fire extinguisher as a pressure tank. Hidden in a cupboard so nobody thinks it's a fire extinguisher. Good for a few seconds of really loud noise. |

I've almost got him sacked already need to lay off the gadgets for a bit. The last one which was the invisiboat system used up so much of the 2019 budget even I was surprised. |

Kruga do a 12v 150psi for about 35 quid. That looks like a decent bit of equipment. It is necessary in this application to use an air storage tank. I tried normal direct vane type pumps used on smaller air horns but they wouldn't touch the horns I am using because they are meant to be run off a reservoir. Which they will be. |

Last one I had was a third generation vogue, the suspension was forever failing. It failed on the m25 at considerable speed and smashed the bloody windscreen. It was the second time in 12 months, so I got rid. Driving around the m25 in safe mode and bouncing on the rubber stops secured its demise. Apart from that, I bloody loved it. |

Just noticed another option for a loud air horn is to use an out of date CO2 fire extinguisher. Not quite sure what the maths is but apparently you get a lot more usage from co2 than from compressed air so you can use the thing as a disposable item.
I suppose some sort of restriction in the air line would be needed to prevent damage to the horn itself.
I've routed 8mm copper pipe over a distance of about 5 feet so that should help reduce the pressure wave one would get from a CO2 extinguisher opening.
As I am using a threaded rod to actuate the fire extinguisher via a threaded plastic ball in front of the Morse controls it might also be worth looking at restricting the opening of the extinguisher valve by adjusting the rod length.
I feel some experiments coming up but don't want to disturb any local humans too much.
