Fitting A Gun Flint To The Lock.
A one sided gun flint.
A Double side gun flint.
Gun flints can be fitted shoulder up or down, depending on where you want the edge of the flint to strike the face of the hammer. Go for higher rather than lower.
Using the turn screw to loosen or tighten the gun flint in the jaws of the cock.
Bevel & shoulder up, striking the hammer face lower.
You can secure the flint in leather or in sheet lead. I have tried both but prefer leather. With the hammer forward & the cock set at half-cock position, fit the flint in loose tightening the screw with just the fingers. Close the hammer [frizzen] over the pan. Release the cock by squeezing the trigger, but hold onto the cock & release it slowly. Hold the hammer in place so the cock can’t push it forward. As the flint contacts the face of the hammer it will straighten the flint & align it with the hammer face.
If the flint is striking the hammer face at least two thirds of the way up, tighten the screw on the cock to secure the flint in that position. Try it out. If it strikes plenty of sparks fine. If not try turning the flint over & test again.
Full cock position.
Fired or full forward position.
