Sooner or later, the farm may need to carry out a very unusual operation, namely, to force a glass bottle so that it does not burst into any case and not cracked in the process. An ideal option for such a "special operation" would be an ordinary nail. However, actually do an even and reliable hole is not at all as simple as it may seem at first glance.
We make markup.
What will take: Bottle Glass, piece of plywood, water bottle, 5 liters bottle, gum and marker, electric drill, nail, drill and shag of the same diameter
Drilling Phaneur.
So, we fold the gum in half, we apply it in this form to the bottle and mark the diametrically opposite points. Having placing holes, go to the next step. For this, we take a piece of plywood and drill a hole in it. After that, we put a plastic basin on the workplace, put a glass bottle into it.
Make a hole in a bottle under the water.
On top of the bottle, we set a piece of plywood so that the drilled hole coincides with the markings done earlier. Now, we take a plastic bottle, we make a small hole in her wall and closing it with your finger - we recruit water. Next, we establish a PET water bottle next to the basin so that later the falling trickle of water fell straight into the hole in the plywood.
Put the Phaneur on the bottle.
Let's let the water, we take a drill with a drill to the diameter and begin to slowly and gently reset the hole in the glass, through the hole in the plywood sheet. We gradually increase the effort and pressure, until the drill will pass the glass. That's ready! Now you only need to repeat everything the same for the second marker mark, on the opposite side of the bottle.
Solemnly insert a nail into reject.
That's ready.
