Now that we have the scales mostly hafted and the liners cleaned up, we can start assembling the knife.
Before assembling, I clean up the springs to prevent any old gunk from jamming up the action after assembly.
Assemble the spring and scales.
Clean up the blade tang to help smooth out the action.
Set the blade in the handle with the holes lined up, and, using your vice, squeeze the tang against the spring until the pivot holes align. Then tap the pivot pin through the hole while it is compressed, and the knife will stay together.
Trim the spring pins with some room for peening, file the pins flat, and peen on both sides until the scales are nice and tight against the spring.
File and peen one side of the pivot pin
Here is where it gets a little tricky. This tool it called a slackener, and as you can see, it's obviously homemade. I got a thin piece of stainless steel from my local hardware store that measured about .01" thick. Cut a strip out of the middle that is slightly larger than your pivot pin, then file and sand down any burs left from the cutting. This tool will allow you to peen the pivot pin without having to worry about seizing up the blades because you peened them too hard.
Slide the slackener between the blade tang and the liner, and tap the peened side of the pin down to the bolster. You want to cut the pin with the slackener in place so that you do not take too much off, and then are unable to use the slackener.
Cut and file the pin, then peen it until there is no longer a gap around the pin head. Repeat this process on both sides with the slackener in place, then remove the slackener, and squeeze the bolsters together to close the gap left by the slackener. Peen the pins lightly, checking the action and blade play of the knife every few taps. The goal here is to peen the pins until there is no blade play while maintaining a smooth action.
File and sand the bolsters until the pins are flush and blend in.
At this point you can start with the final shaping of the handle. Sand and file the scales and back spring until they are even and smooth.
Now she's all cleaned up and ready for a tung oil finish!
Stay tuned for a final reveal with an extra surprise tomorrow!
