If you can make a reference surface, you can make an accurate material by deciding a right angle or a distance based on it.
Anyway, the plane needs to be used properly to make the reference surface.
In order to use a plane, you must first be able to sharpen it.
After all, the most basic and important technique is sharpening and adjustment.
Check the twist visually.
Visual confirmation is a very analog task,
However, the sense of balance that humans have sensuously is quite reliable.
Look closely at the parallelism and set the standard first.
Once you have created a parallel reference in the short story direction, connect the criteria to create a reference in the long side direction.
If you can make this standard, you can make all the shapes.
At this time, it is a good idea to make a chamfer up to the reference line.
When actually processing, it is difficult to see the position where you can check the reference line, so cut down to the reference line while checking that the chamfer is gone.
It’s a very minor and time-consuming task, but the results can vary greatly depending on whether you do it mechanically or manually.
The biggest difference is the ease with which the shape changes after work.
The more you work by hand, the more stable the shape will be.
After making a flat with a plane, use a parallel ruler to check the twist of the material. Place a ruler in all directions to make sure there are no bumps.
When making a material, the material is constantly changing, so you need to carefully check the condition until the end.
The material is alive.
