Use sand and stone to carefully polish and polish the burrs and flash on the surface of the trigger, making the surface as smooth as possible.
After the polishing was complete, Lynn picked up the iron drill and drilled a hole in the trigger, connecting it to the linkage.
The size and position of the hole must precisely match the linkage.
The production of the linkage, like the trigger, also needs to be made of iron.
Ensure that it has sufficient strength and toughness to prevent breaking or deforming during the transmission of power.
This is also why Lynn chose to forge and then quench it.
The shape of the linkage is rod-like, thin in the middle, thick at both ends.
One end connects to the trigger, the other end connects to the hook device of the bowstring.
The length of the linkage is generally around twenty centimeters.
Fine processing completed.
Lynn continued with the next step of assembling and adjusting.
