Hammers are pretty straightforward tools. If you need more impact force, just get a bigger hammer. Alternatively, you can look at enhancing performance with chemical means, and we don’t mean by using steroids. No, instead, you can try hammering with the aid of gunpowder, and [i did a thing] has done just that.
The build relies on using 6.8mm blank cartridges designed for the Ramset brand of explosive nail drivers. However, rather than buying such a tool off the shelf, [i did a thing] built one in a traditional hammer format instead. The device looks like a hammer, with a hinge on the two-piece head, which allows a blank cartridge to be placed inside. When the hammer is swung at a hard surface, the impact triggers the blank which drives the nail forward with incredible force.
[i did a thing] was able to pierce steel with the device, and sent a nail clean through a surfboard, too. It’s a very dangerous thing, so if you’re experimenting in this space, do be careful. Video after the break.
