Re: Help identifying vehicle mount

MG3 mount for an armored vehicle, pictured and explained in the MG3 operator manual ZDv 3/14, which is (surprise) available in English.

Re: Deckungswinkelmesser - Variations

Part 3: The "standard" WWII Deckungswinkelmesser most commonly found, and the only style that I've found shown in any of the instruction manuals. This one is calibrated in mils only. A circle is commonly divided into 360 degrees. A mil is 1/6400 of a circle (17.77 mils are in a degree). A ...

Re: MG3 Barrels, Bolts and Headspace

I think your search for the source of the problem has been successful. Now I have to wonder if the Germans figure that needing a little bump at the end is considered within specs and the let it break in to working effortlessly like we're used to with the slightly worn and worn barrels we normally fi...

Re: MG3 Barrels, Bolts and Headspace

It would seem that what I posted in my first reply was a disaster - caused by staying up until 4am translating German (best excuse I got), and not being fully functional when I first got up this morning (at 10am). My suggestion works well enough for HK stuff, but not for the 42. Sorry. I'm not even ...

Re: MG3 Barrels, Bolts and Headspace

Headspace might loosen with wear, but it would take a few thousand rounds. I'd probably try a steel bore brush on a rod mounted in an electric drill, with some valve grinding compound on the brush to see if a few thousandths could be taken out of the chamber. The success of that will depend on where...

The WWI Deckungswinkelmesser

Part 2: Here are some pictures of a World War I Deckungswinkelmesser. This would be appropriate for indirect fire with the MG08 . It has the scale in the little window calibrated in degrees. The scale window is looked through on the side without the centimeter scale, and this has a loop for hanging ...

Re: New Run Of .308 MG42/M53 Barrels

The barrel itself is only 1/3 of the headspace variable. The other two are the barrel extension, and the bolt. All three need to fit together properly to get the headspace, but the barrel and barrel extension are the two that are able to be adjusted (chamber depth, and how far the barrel is screwed ...

Re: New Run Of .308 MG42/M53 Barrels

Certainly not trying to rain on your parade, but: Are you talking barrels with or without the barrel extension? If without, then they will need set up and the chamber reamed or the barrel spaced or trimmed to get proper headspace. There's a lot of work to make a fireable barrel. Getting a barrel the...

Re: Lost a Good Friend Today

With the class 3 community as small as it is, it's always sad to lose one of the good guys in it.

Sh!t happens, life goes on, or not. Been there, done that. I was just luckier than some.

Re: Binary trigger??

Using a registered drop in auto sear for an AR15 would be an interesting project. You'd have to figure out how to get the timing right (how to make the bolt bump it at the right moment to release the hammer), but I don't see why that couldn't be done.

Re: Binary trigger??

Not sure what kind of answer/advice you're looking for here. You could mount a binary trigger. If it's legal for other firearms, it should be legal for a semi 42 firearm. You could mount a crank device. If it's legal for other firearms, it should be legal for a semi 42 firearm. You could mount a bum...

Re: Bought Vickers kit, Help & need info

I remember that such seals used to be made of cotton rope or cord, which was covered with graphite. It was flexible enough to seal very well, as the water jacket doesn't have any pressure in it. A thin cotton clothes line could be boiled in water first, then greased or graphited. It will take some t...

Well, after I get done building a roof over the back steps, it will be basement time for me too. Gotta drywall a few walls, finish a bathroom, and maybe put up a door or two. Welcome to the joys of home ownership.

Yeow. You lost 2 days. Last time I fell off a roof I only lost about 5 minutes (I think). It took about 8 months before that last rib decided to quit moving around though. At least you didn't do the broken neck thing. We're getting too old to be doing this sh!t.

The gauge inside is calibrated in degrees (instead of mils), and percent. The body and outer frame of the deckungswi...
