Wood. Humans have burned it for to heat their homes for thousands of years. It’s truly a renewable source of energy. While it may not be the most efficient or green method to warm a space, it definitely gets the job done. Many homes still have a fireplace or wood burning stove for supplemental heat. For those in colder climates, wood is more than just supplemental, it’s needed simply for survival.
The problem with firewood is that it doesn’t come ready to burn. Perfect fireplace sized chunks don’t grow on trees after all. The trees have to be cut up into logs. The logs must be split. The split wood then needs to dry for 6 months or so.
Anyone who’s spent time manually splitting wood can tell you it’s back breaking work. Swinging an 8 pound maul for a few hours will leave your hands numb and your shoulders aching. It’s the kind of work that leaves the mind free to wander a bit. The hacker’s mind will always wander toward a better way to get the job done. Curiously we haven’t seen too many log splitting hacks here on the blog. [KH4] built an incredible cross bladed axe back in 2015, but that’s about it.
Firewood aficionado and general axing enthusiast [KH4] likes to cut and split his own fire wood. To burn a tree trunk sized piece of wood efficiently, it has to be split into 4 smaller pieces. [KH4] does this with 3 axe swings, the first splitting the main log in 2, then splitting each half in half again. Although he likes swinging the mighty axe, he still would like to increase the efficiency of each swing.
Well he’s done it! This is accomplished by making a Cross Bladed Axe that has an X-shaped head. Each axe swing should split a log into 4 pieces. That results in 66% less swings for the same amount of wood split!
This projected started with two spare axe heads. One was cut in half with an angle grinder. The two axe head halves were then ground down so that they match the contour of the original axe head. Once the fit was good, the welder was broken out and all 3 axe head pieces were combined into one beastly mass.
After the new head was polished and sharpened, it was re-assembled a new hickory handle. We have to say, the end product looks pretty awesome. There’s a video after the break of this axe in action. Check it out!
[Maurice] let us know that his latest photography tool for hackers, the Camera Axe 3.0, is now available. The original allowed you to trigger a high-speed flash and camera from a multitude of sensors, including light and sound. The new one does all that, but also: allows multiple cameras or multiple flashes, clean up of software to make it more user adaptable, and the best (arguably the most important) part – cheaper components! All that and more under the Creative Commons that we do love so much. Keep up the amazingly detailed and just pure awesome work [Maurice].
