A smaller piece of steel, knurled and turned.
Tapping #8-32. The drawing calls out #8-36 but I'm a rebel. This does have implications down the line...
Parted off.
Mounted on a mandrel for facing off.
Done!
Now the aperture. Turned to diameter.
Threaded #8-32
Drilling the major diameter. I reduced it a bit from the drawing to take into account the deeper thread depth of the #8-32 over the #8-36 (A difference of .003" thread depth)
Drilling the aperture hole. I also reduced this, but mainly because I like a smaller aperture.
Knurling.
Parted off.
Blurry picture of boring out the face.
Blued with Oxpho blue and mounted on the rifle. Works fine. It's a fun and accurate rifle to shoot.
