In Finland splitters, in addition to the normal cleaver, also used cleaver lever with a displaced center of gravity. Because of its structure when immersed in a piece of wood he pushed to the side, due to which it breaks with less effort. This reduces the fatigue of firewood, and in addition the displacement of the centre of gravity prevents the blade jams in the wood. In the factory version, this cleaver is not cheap, but it can be welded using an old truck spring.
- thick spring from the truck;
- thick-walled pipe 50 mm;
- piece of wood under the handle.
The process of making an axe
In the construction of Finnish log splitter has a lever to make it, you need to bend the spring at right angles. This will require a cutting torch to heat the metal to bend. Otherwise, the cold spring simply breaks.
For bending, the blank is heated red-hot, clamped in a vise and bent at the mark 40 mm from the edge.
After cooling, the spring is clipped over 140-160 mm from the bend.
The edge of the resulting blank to sharpen. At the end of the bend and the main part we need to display the slopes on the outer side.
Given the thickness of the springs for that it is better to first cut the corner of the grinder with the cutting disc, and then to bring the sharpening on a belt grinder or the winepress. The descent on the chopping part is supposed to be concave, as in the original design. Concavity can be obtained if applied when sharpening the grinding disk edge.
To install the ax you need to attach to the blank eye. For the thick-walled tube 50 mm is cut a piece of length equal to the width of the spring. It should flatten. You can do a couple of strokes of a hammer on cold with no warm-up.
Next, you need to weld the eyelet to the blade of the cleaver. It should be located at the side of the lever. It is important to expand the pipe so that it was possible to arrange the tip of the cleaver and its most distant points in a line. The towing eye is welded in that position.
Then stuffed cleaver axe-handle so that the hook was on the left. Since eye custom, then purchase the ax will not work, it will have to whittle your own. Arm is fixed, as in conventional axe, by wedging from the end.
If you use a cleaver with a shifted centre of gravity during the impact, he in addition to the forward displacement also shifts to the left. Due to this, the beam is split, and the ax clings lever to the left in the remaining part of the log, so it does not fall. This allows you to immediately apply the next blow, shattering it on the wood of the necessary size.
