Impact Drill Train Horn Build

[Hammer Down]

Hammer’s homemade impact train horn build.
This was one of the more fun projects I’ve done in awhile.

What’s involved you ask..? Well it’s pretty simple and cheap if you have an old cordless impact or drill laying around. Then all you need is this $30 horn and compressor kit found on Amazon. A dremel with some accessories (grinding wheel, sanding drum, rasping bit), a Phillips screwdriver, a soldering iron if you want, heat shrink, hot glue gun and some patience.

First off start by disassembling the impact/drill. Remove the motor assembly and clip the wires as close to motor as possible. Then clean out dust and dirt if it’s old like mine.
After it’s all clean you can start by test fitting the compressor. Mine fit with almost no effort at all. Just some light dremel work above the trigger was all it needed. Also had to make some clearance for the compressor wires (rasping bit) but overall super easy.

After you fit the compressor in the drill housing, you can connect the wiring from the trigger to the clearly marked +/- posts on the compressor. I chose to splice the existing wiring to the wires that came with the compressor. Mainly because they already had connectors on them.

Once all your wiring and compressor fitting is done you can hot glue, epoxy or whatever you choose to hold the compressor firmly in the drill case. Then reinstall all the screws holding the case together.

Next is the mounting of the horns. I decided to slot them into the back cover of the case. As that was the cleanest and easiest way. Once the slot was how I wanted I was able to drill some holes in the back cover and bolt them on solid.

Finally put the back cover on, cut the air line to length and install between the compressor and horns. Install a battery and some ear plugs.. and let’er blow!

This was a super fun and easy build. Plus if you have an old impact or drill it’s pretty cheap.

The led light still works too!

Somebody is about to be a bit mischievous!

Part of me wants to drive around and blast people that are texting while driving!
The other part fears they’ll run into me cause I scared the sh!t out of them.

We need a video of it in action where the mall walkers get their groove on.

The horn on my little Honda HRV is pretty weak. This is what I need for my rush hour commute, instead of the middle finger!

You have an old drill? You could build one for cheaper than it would cost to ship it.

I do have another old drill laying around tho..

 

[WickedFog]

Lol. No, I dont, but I could buy a cheap one. I would just get in trouble if I had one

Can you do it to any drill or does it have to be a certain brand/model?

Any brand should work. Might have to get creative on fitment. There’s a company that makes them but they’re way overpriced for what they are. You can build one for $30 if you have the donor already. They charge $170-250.
