    Default MG42 Build Question

    I'm trying to get a measurement for the hole on the LH side of the receiver for the camming piece (aka trunion). I'm doing mine up via Pirate's build method, and before I screw something up, I'd like to get a 2nd opinion.

    What I'm unsure about, is how tight the camming piece fits into the hole, or if the hole has enough front-to-back play to give the camming piece some wiggle room. Therefore I'd like to simply get a measurement of that hole's front-to-back dimension.

    I'm working from an Angola 3-cut receiver, the middle cut is directly through the hole.

    On the RH side, the barrel removal door is said to "lock down against the camming piece"... on mine, I cannot see a wear mark on the camming piece and the end of the door isn't worn. That leads me to conclude that there is a slight amount of clearance, about as thick as a business card, between the door and the front of the camming piece - is this correct?

    I'm posting here since I figure I'll get a faster response than the MG42.us forum

    FYI, Pirate's build info is really helpful. I'm documenting mine to have some pics for the 'ol album.

    Yep, you have a good pic of the assembled part here:

    Now all I need is the measurement of the hole it inserts into!

    FWIW - I've seen some with slop and some that have had the sides of the opening in the receiver peened to close out any slop.

    I bow to Pirate's knowledge


    Did I do that?

    Will;
    I'd guess you're measuring off your BRP receiver?

    hc;
    Here's three photos off BRP parts kit scrap receiver sections. Caming pieces Waffen marked German WWII. Receiver section stamped bpr (WWII German). The first two are of the left side of receiver. Front part on left side of receiver the sheetmetal looks beat on to snug up gap. The back part of the left side appears to have been soldered at some point (silver solder). The rear of the right hand side of the receiver section also appears to have been soldered. Based on this info I'd say it should be snug

    I'd still like to hear from Pirate.

    no , i have a camming piece on my BRP reciever [gun shoots better with it on] , I have a cut German reciever on another kit here I measured off. it's cut, but pretty clean ,a couple square corners . Bubba Neass told me that there should be a wee little bit of play, but not enough that you'd notice it . Not sure how that translats into a "do this" , but , there you go . Pirate , chime in !

    Didn't know if you could get a pair of calipers in your built weapon and get measurement after removing the barrel.

    Whadda mean you don't want to cut the rivet and remove the caming pieces to get a measurement of the receiver opening

    I've seen several with a small gap. Not sure what the spec is and how to quantify "small gap"

    BTW #1 the receiver section in photo above has a small gap but it's filled in. Could have been done by the Yugoslavians ??? Maybe not per spec

    BTW #2 - getting cold in Baton Rouge? Geez it's into the 30s here.
    I like to have fun with the guys who live up North----up north of I-10 that is


    Did I do that?

    mine fit tight, I also have a used brp receiver and it looks like tha cam was welded on. The cam sections need to slide together easily so there is no gap in them
