    Nice work, I love to see homebrew stuff like this.

    Is the magic of the belt feed in the top cover and tray? I have never had a beltfed weapon, so this is all new, and very interesting to me.

    SS -

    You're right. I have an RPD BC, and the feed stud is off-center to the left. It will take some engineering. I've had a few problems with the bolt & BC UNLOCKING - need to get that straightened out first. Most of the other build basics are falling into place nicely. Will be using a twin-spring set-up much like 2XTM's, but simpler to build, using UN-captured springs

    The piston / gas tube set-up is well underway. You'll like it - pics will be coming along when I get time at home

    here is mine so far, I am using one of my semi auto mg42 grip sticks with a fal fcg.
    I bushed the rear hole so it mounts fron & back with HK forearm pins. next step is to install the feed stud and recoil spring. I am holding off on cutting the ejection port & retracting slot till I can get to a mill.

    I am also working on drawings to get a couple receivers laser cut and bent if this turns out good. After looking at it I have come to the conclusion it really neds a set of spade grips in the back instead of a stock. I will try that after this one is working.

    Really looking great! Very exciting stuff

    I found a supplier who carries 1 1/8" sq tubing in various wall thickness, that will fit the RPD TC latch - have been on the road but will post the name and link when I can. That size is difficult to come by

    Are you going pistol or carbine? Pistol is real tricky gas-pressure-wise but I think I have it figured out and will post the 'trick pics' when I can

    I wish I could weld as good as many of you can. I am envious but am practicing

    Your build is really something. I hope you'll share more pics here as you go

    Thanks

    Steve

    If you need 1 1/8" for the RPD TC, this place carries it.

    http://www.aladdinsteel.com/catalog/square.html#118

    It's the only place I found that markets 1 1/8" - have since learned minimum purchase is $500

    Edited 3-4-08

    Found another place: http://www.tubularsteel.com/products_squarerect.asp
    They too only deal in large quantities - lady on the phone said they'd send a free 5' "sample" and ship it for free

    Why would you need 1 1/8" for the RPD cover?
    Thanks for the link.


    OK now for my stupid question of the day.
    I never thought about this until these belt fed builds started but what is the actual purpose of the upper left rail ( I know the right is for the ejector ) and I know it would be the same as the lower right in an AK, it doesn't seem to have any real purpose or does it?

    Coils -

    The rear of the TC where the latch is = 1 1/8" wide

    The 'left upper' rail is to keep the bolt from rotating when cycling. It's easier to install than the ejector rail, and is full length. Ejector rail does not necessarily need to be full length
