    Default RPK in the making

    This is an RPK in the making


    This is the internal support for the receiver I use, and the clamping to prevent vibration.




    I have one for the standard AK receiver also


    Here?s the front trunion fitted


    Another of the front trunion


    The receiver is still over length at this stage


    Both sides are relief cut for the rear trunion


    A balding beaver LOL


    Bolt carrier removal slots


    different angle

    Wyoming hasn't changed from the last time I was there. A blizzard collapsed my tent on me at night and the next day I thought I'd die from heat while dragging an antelope.

    It's beautiful but best enjoyed looking out a window!! You're doing it smart.

    The Saga continues.
    Milling the bottom side and spotting and drilling the rivet holes.
    The cross braces and rivets are on back order.


    Marked and ready
    Dykem blue with cutouts marked

    cutting the mag well, trigger hole and pistol grip nut hole

    Making sure the rear trunion is 90 degrees to the work table and in line with the drill bit

    first look for hole center

    different angle for centering the drill over the hole

    The pilot hole is drilled after locating the trunion hole and slipping the receiver in place

    locating rear trunion hole in receiver, the receiver will be slipped on the rear trunion and drilled, This is just one of many hole locating techniques

    using the center drill to locate chuck over rear trunion hole for drilling through receiver

    drilling both sides for rear trunion

    rear trunion holed drilled through both sides receiver clamped to mill table

    front trunion hole piloted

    Aligning the Cener drill with front trunion locked in the vise

    drilling the pilot hole

    pilot hole drilled

    Front trunion hole finished

    Front and rear trunions fitted and tested, Carrier runs smooth
