Hey group,
I'm building a custom pistol for myself. (1911 baby!) I have a slide with no cocking serrations. Would like to get a 20 lines/inch checkering job done in this area. Slide is 4340. I'd need two rectangular-shaped areas 1.270" by 0.840" and two areas 0.930" by
0.840".I think this would be an EDM job... if anyone has suggestions I'm all ears. But willing to pay the $ for a job well done.
