Carving the grooves on an extractor star
Latest steps in making a SW 44 Russian extractor star. Fixtured the extractor on a block of wood with CA glue and hot glue to fit in the jaws of an engraving vice under my engraving microscope to keep things as accurate as possible. I made a small jig out of brass to mark the distances between the individual grooves in sheet brass, this was used to mark the dimensions of the protrusions on the star with a graver. Then used a Dremel and files to cut the individual grooves, this is interesting as they are 3 d complex but I am happy so far. I will cut the initial grooves and then further file and fit until they turn the cylinder to proper battery and index smoothly. Will update when I have either failed completely or have a working model. Nothing is impossible.
