He's very pleased that neither of these two items have cracked.
Next, he attempts to insert the spindle into the circular hole between them.
The hole in the disk is now a bit large, making the spindle fit loosely.
The hole in the clay brick is a bit small, making it impossible to fit the spindle in.
So he uses a stick to vigorously grind the hole in the clay block, expanding it slightly.
The scraping sound between the wood and ceramic brick is extremely grating.
He grits his teeth to endure it forcefully, scraping for two hours in total, finally enlarging the hole somewhat.
Then he first inserts the spindle into the forty-pound clay block used as support, which is now baked into a brick.
The clay block is the support for the spinning wheel. Now, the spindle along with the front wheel is suspended in the air.
Next, he sets the disk, also known as the spinning wheel, onto the spindle.
The prototype of the spinning wheel is effectively taking shape.
