A square bar shaped "ridge" can be welded to the hammer disc to achive half-cocking effect. The position of this bar can be decided this way: strip one of your good gun, replace the hammer with the "project hammer", put main spring, coupling, and sear back, hold the lock frame, raise the sear manually to release the hammer, then push the safety level up, and lower the sear to its normal lower position. Now you will notice the position of the hammer disc directly under the back edge of the sear, mark that position on the hammer disc. You will also notice that position on hammer disc is about 2m/m lower than the sear edge.

Cut the sqare bar length to the width of the hammer, the height of the square bar is 2m/m, the width is not very important, but for welding stability, it cannot be too narrow, say at least 1m/m (?). Weld it to the marked position on the hammer disc. I am sure this new 2m/m "ridge" on the hammer disc is too high. You have to file it down manually little by little to achieve half-cocking effect. But three things must be observed

(1) The top of this new "ridge" should not go out of the lock frame. Otherwise, it interferes with receiver movement;
(2) When you push the trigger to release the cocked hammer, this ridge will not block the hammer; and
(3) Of course, it must achieve conventional half-cocking effect.

Hope this helps. Good luck!
