Those who were engaged in plumbing, various repairs of cars and motorcycles, probably found themselves in a similar situation when they had to drill out a washer exactly to the required diameter. It would seem, take it and drill it out, what’s the problem? But not everything is as simple as it might seem at first glance.
If the washer is narrow or made of thin metal, then it will simply not be possible to hold it or clamp it somewhere.
If you hold it in a vice, it will most likely become wrinkled. And if you hold it, say, with pliers, then the hole will not be even, since the washer will jump around when drilling.
Drill out the washer evenly with your own hands
I will be using a tabletop drill press. Everything needs to be done on a wooden board. Without starting the rotation, lower the drill close to the washer, thereby centering it evenly.
Carefully lift the drill without moving the washer. Place a wooden block on top and press it with a clamp. Then we start the machine and drill the block with a sandwich with a washer and a bottom plank.
We remove the block. Pick out the washer, as it was pressed into the tree.
In this simple way, you can bore the washer evenly and accurately without any extra effort.
If necessary, you can grind off unevenness and burrs with a file.
How to bore a washer with a regular drill?
We take a drill with which we will bore the washer. We drill a through hole in the block in advance. Then place the washer on a wooden surface. We place a block on top, adjusting the holes in the block and in the washer by eye. Clamp with clamps.
We drill with a regular drill or screwdriver.
Such tricks are very helpful in life, especially for those who know them.
