He placed the complete rabbit skin fur-side down, spreading it flat on a clean stone slab. Then, he inverted the rectangular wooden piston head onto the center of the rabbit skin.
First, he used some heavy stones to weigh down the piston head, preventing any movement. Then, with a length of steel wire tripwire, he used a cross-stitch method similar to sewing leather boots to pull up the edges of the rabbit skin, wrapping it tightly around the side of the piston head, and folding it over the top.
Once all the tripwires were tightened, the entire side of the piston head was encased in a complete layer of rabbit skin.
The soft, fluffy rabbit fur naturally spread outwards, forming a perfect, self-adjusting sealing "skirting."
A piston head with a perfect sealing ring was now ready.
He moved to the other side of the fishing float box, carefully creating an opening just big enough for the piston rod to pass through using a red-hot steel rod.
