The photos will detail making and engraving new screws to replace the damaged originals.
Here are the floorplate and triggerplate screws as the gun came to me. I had to machine the floorplate screw out because the slot was far too mangled to use any sort of screwdriver.
The screws are removed.
The new screw blanks have been machined and installed with the slave heads. The slot locations and rough height are then marked and the screws are removed and cut to their approximate height.
Once the heads are cut down, the slots are cut.
The screws are then reinstalled and filed flush to the surrounding metal.
Then they are engraved to match the originals.
The finished floorplate and triggerplate screws. I use a 20X Amscope microscope and push gravers for the engraving.
Here is the breechscrew. The toplever screws were made the same way.
The screw blank machined from barstock.
Slot cut and filed up.
