Which is an easy way to save a lot of time grinding

This is a really simple way, and many probably known.

When the grind of wood products, they usually begin to polish the sandpaper with a relatively large grain, and then gradually move on to nazhdachku fine grain.

In conventional top-lit work space and see how well polished product can be very difficult.

But if you highlight detail side.. for example a lamp. That is almost direct light along the surface of the part. Then all the scratches will be very visible.

There are specially made such obvious scratches, as the photo is difficult to convey what is seen through the eyes.

On the side you can see the light scratches that remain even nazhdachki fine grain (number 120 and above). Inspecting detail so it's easy to control the quality of grinding.

Otherwise, you can find a scratch, when he began to paint. And if it turns out a lot of scratches, it will need to be sanded again. And after even a single layer of any coating, and grind hard sandpaper clogged very quickly.

And in the old books on the carpenter's shop, it is recommended after grinding to wet the surface to raise the nap. Upon wetting can also see all the flaws grinding.

But wetting, for whatever reasons, they are often neglected. When I worked in the carpenter's shop on doors and windows, after grinding has never happened and wetted parts for painting swore to nazhdachku and polishers, which leave such notable "vilyushki"

I am watching as many videos on the carpenter's shop on YouTube and have never seen the use of wetting parts after grinding.

Possible refusal of wetting parts to remove the pile associated with an increase in the time of manufacture or with the hope of Abrasive modern quality, and can in that all the same after the first layer is polished finish parts to knock pile. Or maybe even with what ...

Again, I go back to the light. If such a simple action helps to improve the quality of grinding, then maybe it makes sense to introduce this rule.
