The size of the stones to be split, as well as their origin, is absolutely not important. The hardness of the rock is important. Softer stones are less likely to split or crumble altogether. The harder the stone, the more beautiful and smoother it can be cracked.
I recommend chopping stones with wedges. This is the most convenient and fastest way.
What mistakes should be avoided when you prick a stone:
Do not drill shallow holes, such as in the floor of the drill.
The depth of the wedge hole is selected based on the length of the wedge, not the petals. For example, for a wedge 12 cm long with petals 6-7 cm, holes must be drilled at least 12 cm deep. If the wedge is completely hammered, then it should not rest against the stone.
Do not take the drill at random.
The diameter of the drill with which you will make a hole for the wedge in the stone must match the diameter of the wedge.
Do not drive wedges into the stone where necessary, along arcs and broken lines ...
The holes for the wedges must be drilled in a straight line. Because we need even stones for construction. Moreover, the smoother the sides of the stones, the better.
If you find it difficult to immediately drill holes in a straight line by eye, you can use a template - a flat board or a metal bar - depending on what you have at hand.
Don't look for veins.
Practice shows that it is best to split stones in the middle. I do not recommend looking for veins or fractures in the stones and trying to split the stones along their path. Because the stone will probably crack crookedly.
Do not make holes for wedges too close together or too far.
The distance between the two wedges should be 15-25 cm.
Do not insert wedges incorrectly into the stone.
The edges of the wedges should be inserted into the stone clearly along one line, along the fault line.
Do not drive wedges into the stone immediately and sharply.
The wedges should be driven in slowly, in order, gradually immersing them in the stone. And pauses between sets in 2-3-5 seconds.
At this time, the stone itself splits along the trajectory set for you. Therefore, he must be given time to "think" and "take a breath of air." Then you will hear a characteristic sound, the crackling of a stone.
Don't forget about safety precautions! Don't show weakness! No distractions!
When you need to separate the chipped pieces of stones, use special tools: a pickaxe, nail pusher, sledgehammer or crowbar.
If you grasp the stone with your hands, do not release it, or release it very carefully so as not to pinch the limb.
Watch the movement of the stones as you separate them from each other. They can suddenly change their trajectory and crush you!
Do not be distracted by extraneous affairs and conversations, be completely focused on your business and do not show weakness - this will also significantly reduce the risk of injury.
Do not miss the wedge and hit the rubber band.
Such mistakes happen to both beginners and experienced craftsmen. They interrupt the rubber bands. Without rubber bands, of course, wedges can also be used, but they will be less convenient in work and the working time will be a little longer.
Stones can be split not only with wedges, but also with other devices. For example, if you don't have wedges available, cut the reinforcement, sharpen it at one end, and drive it into the stone. The stone will also inject, but this work will take more time.
