He had very high demands for measurements.
This was to reduce troubles during later assembly and to leave data for future primitive woodworkers.
His sanding was quite standard.
Considering how strong his obsessive-compulsive disorder was, earlier weaving and spinning had required countless effort, and later stone could be used to process various tools. Now, with iron tools, the standards had to be set even higher.
There was a certain error in dimensions when sawing.
He would call for help to saw together, drawing lines well.
He continuously sawed several wooden planks over a meter long, more than twenty centimeters wide, and about seven centimeters thick.
For sawing out thickness, a scroll saw was used, which was relatively more accurate.
But handmade sawing definitely couldn't match the standard dimensions pushed out by a table saw.
Then a planer was used for planing, and a sharpening stone for grinding.
He spared no effort.
