LMG25: Build 2

Cold War, Custom builds, Inter-War (1918-1939), LMG25, Machine-Guns, Weapons, WWII

At the end of the last post, I had most of the large components roughed out for the LMG25. However the cooling ports in the barrel jacket are a little rough at the ends.

_DSF9154

So I welded the outsides edges, so I could grind them down and round out the ends.

_DSF9158

Next I welded up the ejection port.

_DSF9257

And the rear sling swivel, attached to the mount.

_DSF9263

The bipod was an interesting challenge. In order to go from the stowage to the deployed position the lugs all have to rotate, so a little tweaking was needed to make everything move freely.

_DSF9264

The end result is a pretty stable bipod with good movement, allowing the operator to sweep over an arc of fire.

_DSF9265

The dry assembly of the rear sight and ejection port. From this I learned that the ejection port needed a little trimming off the bottom to sit tidily. I also decided to chamfer the edges of the rear sight base to get a deep penetration for the weld.

20170615_161208

The foresight has been 3D printed, it screws into place on the barrel jacket.

20170615_170539

It sits just ahead of the bipod.

20170615_174938

The back-cap is also printed, I may replace this with a cast aluminium version now I have a working kiln.

20170615_175019

Most of the remainder of the work is now detail parts such as the rear sight unit, operating handle and the attachment for the back-cap.

MG08/15: The last furlong?

Custom builds, Imperial Era, Inter-War (1918-1939), Machine-Guns, MG08/15, Weapons

Thos of you who have followed Vintage Airsoft for some time will recognise this and be like: “Is he STILL working on that?”. Well, yes. I swear if something could go wrong on this build, it did. At least once. 

So, here’s hoping this is the last build post at long last!

One of the problems was the air seal between the gearbox and the hop unit. This it turned out was caused by flex between these parts, resulting in variation from shot to shot.

 

In the end, I re-designed the mounting plate to feature a hop-up ‘vise’ to hold the unit in place really solidly. There isn’t any wobble in this sod. 

_dsf8416

I had to make a few mods to the trigger unit design and the bottom of the baseplate to work together, but now the trigger raises a sear which sets off the microswitch in the gearbox itself.

_dsf8466

In place, clamped down! I’m still using the same feed system as before. 

_DSF8684

The feed tube comes out to meet the magazines.

_DSF9120

Oh yes, new grips. I wasn’t happy with the old ones, one wasn’t quite spot on, but as with all things the second attempt was much better. I’ve used hardwood this time (as opposed to laminate) and cut in cross-hatching for grip.

_DSF9140

Topping up the paintwork. 

_DSF9161

I’m really looking forward to having the finished photos on this at last.

LMG25: Build 1

Cold War, Custom builds, Inter-War (1918-1939), LMG25, Machine-Guns, Weapons, WWII

The LMG25 is a really weirdly formatted gun, but with a Sten and some modifications I’m hoping to make something really interesting and unique.

Screen Shot 2017-04-07 at 00.19.41

As ever, this started with a load of research and design work. There aren’t too many parts to this compared to some of my builds and they nearly all attach directly to the receiver. The first step of construction was to make this receiver, which I made a template for and centre punched for the drill, before cutting the space needed for the donor.

_DSF8702

_DSF8934

The welding begins with the mock-upped ejection port and the trigger grouping/pistol grip.

_DSF8863

I also cut a hole for the magazine feed.

_DSF8935

The magazine well has an awkward and distinctive shape, so it is being 3D printed and will be mounted with metal plates and screws to the receiver.

16810116_587428191446607_1100663209_o

In place it fits quite nicely! This replica takes AK magazines which look the part well enough from a distance.

20170406_150322

Onto the stock. I cut it out in the usual way from the blank, but I can’t cut out the action recess in the usual manner due to the awkward lump at the front of the stock. It would have been possible to have this as a separate piece but it’s not a major issue to work around.
_DSF8964

The pistol grip unit is, fortunately, an entirely separate unit. This means making it is a lot easier than a one-piece pistol grip/stock. It somewhat resembles some of the early semi-auto conversions of bolt-action rifles in this respect of its design.

_DSF8965

There is quite a pleasing curve to the back of this pistol grip which is easily missed.

_DSF8966

This means that all the major working parts are in place. The next important step is to get the working parts actually working! Then we can enjoy the detailing, sights and bipod.

The LMG25 Furrer

Cold War, Custom builds, Inter-War (1918-1939), LMG25, Machine-Guns, Weapons, WWII

The LMG25 is a Swiss Light Machine Gun adopted, as the name suggests, in 1925. It is a real oddity, even for a time when LMG designs were far less standardised than today.

2911f7d87f8fe97e_large

This Swiss soldier will get a very warm thumb if he opens fire now.

It was developed at Waffenfabrik, Bern by Adolf Furrer over seven years and was produced until the end of WWII. It served into the 1970s with the Swiss military, so must have been a pretty serviceable firearm to have hung around for so long.

9a332718e1440472_large

So, why is this an oddity? Well, the magazine is on the right-hand side, when most side-feeders (though not all) feed/fed from the left. There was a monopod at the back for support during sustained fire which wasn’t an uncommon idea at the time, but this could be moved to the front and used as a foregrip, which was.

lmg25assault

Monopod used as a fore-grip in the assault role.

But most interesting of all, this is a toggle-locked design. There are very few toggle locked guns due to the complexity and expense of manufacture as it is. There are even fewer rifle-cartridge toggle-locked guns (especially that went into production). As well as the high level of accuracy required for these to function, they also need to have a very strong recoil spring and a conventional toggle-lock doesn’t provide great purchase when cocking. The LMG25 has a separate operating handle to aid with this.

lmg25-28

The LMG25 is also interesting because as well as being toggle-locked it fires as you would expect a support weapon to do, from an open bolt. It is the only firearm of which I am aware that is both of these.

lmg25-8

The open toggle. When opened, it kicks open the two-part dust cover. Anyone familiar with the Luger will recognise the parts of this.

Just in case this wasn’t different enough for your liking, it is also unconventional in that the barrel does not stop once the toggle is broken open but keeps moving backwards. The shell is still ejected as the toggle moves much faster than the barrel.

dustcover1

The dust cover in the closed position below, and open above. It is in two parts to fit around the toggle. Very Swiss. 

In spite of all this strange-ness and the alleged complexity of toggle-locked guns (over-egged by those who have spent no time with them) it is very simple to field strip. One large nut at the back of the receiver allows you to remove the recoil spring, then pull out the barrel assembly. What about the bolt? Well the bolt/locking mechanism is all part of the barrel assembly on this so the whole lot pulls out together. Neat for cleaning in the field.

lmg25-14

The barrel/bolt/locking unit, showing the extravagant fluting on the barrel normally hidden by the shroud.

lmg25-26

Top view of the toggle when removed from the receiver.

While beautifully made, this type of gun never really caught on. It served the Swiss well, where money was no object for a relatively small army but for any other military the expense would have far outweighed any advantages. 

lmg25-3

Of course due to never being adopted outside of its home country, which didn’t participate in any conflicts during this period (or ever since about 1847) it never saw active service so it is difficult to say how it would have performed. 

 

If you want to see some footage of the LMG25, Ian at Forgotten Weapons has a nice video talking through one in Belgium here:

He also has some awesome footage of another LMG25 firing, including a lovely bit of slow-motion:

Don’t forget to check out Forgotten Weapons’ page on the LMG 25 here for more information on the gun and high-res pictures.

Vintage Airsoft will be building an LMG25 over the next few months with progress posted up here.

PZB 39: Build 3

Anti-Tank, Custom builds, PZB-39 Rifle, WWII

The basic components for this build are all in place, now it is time to add in the parts that pull it all together.

Next up was to fit the buttplate, the top half of this is fixed in place but the bottom folds in to help the rifle pack up smaller for transport. 20161129_141747

In the folded position. Once the cushioned pads are in place it won’t fold quite as far as this but it allows it to fold a lot closer than it would otherwise.

20161129_141757

I have now planed the stock down to its rough shape, adding the grooves with the router. If I was doing this again, I would definitely make these grooves sooner as achieving a straight and level cut on this shape is quite tricky!

20161129_141734

The forestock needs another mounting point further back to really solidly hold it in place, I expect I will have to make some kind of band that slips around the action as the bottom of the tubes at the chamber end are all cut open to hold the airsoft parts. It may make sense to combine this with the rear sight, which is still yet to be mounted.

20161129_141659

The rear sight fitted in position. This is welded into place on the front. I decided not to use this at the attachment point, instead adding a second screw well behind the first one.

20161202_172644

Taking the buttstock home, there are a couple of bits of fabric work for this build. Firstly, the leather cheek rest, presumably added to keep the cheek away from cold metal. It certainly doesn’t provide any great cheek weld.

The second part is the cushioned buttpad, to absorb the not insignificant recoil on the original!

20161206_000559

The leather cheek rest is laced on so it can be removed easily. The originals were sewn on but this looks the part and makes it easier to remove and maintain.

20161205_162729

I have to make the carry handle covers, fit the foresight and re-assemble to paint it, but that’s the majority of work to come.

_dsf8423

In the meantime, the trigger unit cover and pistol grip. I already welded the grip together, at this stage I used a bolt to line up the hinge points and the grip over the cover plate. This can be tacked down so the whole unit swivels as one.

_dsf8424

In place. The receiver was slightly out of square, so I used a clamp to hold it in place while I made adjustments.

_dsf8426

Although the pivoting grip unit doesn’t cycle the action like the original, it will be useful for disassembly.

_dsf8472

It opens much like the original.

_dsf8473

_dsf8474

At the front, I now have a cover plate for the magazine well, which can be swivelled aside to access the magazines and change them.

PZB-39: Build 2

Anti-Tank, Custom builds, PZB-39 Rifle, WWII

The next step is to make the new bolt action. This allows the bolt to be used without cutting out a section at the side of the receiver.

_dsf8124

The front section locks the breech and operates the out of battery safety. The knob at the back keeps this in place and allows the user to grip the bolt to operate it.

_dsf8139

The receiver of the donor rifle (a VSR clone)  screws into the receiver of the rifle.

_dsf8151

The top of the receiver is welded in place, as are the thick back parts of the barrel. These also support the weight and hold the position of the internal parts.

_dsf8183

Slowly, I add on the rest of the barrel. To simulate the tapered barrel of the original I am stepping it down slightly along the length at opportune positions.

_dsf8192

This thing is now huge. It is already longer than the G98, even without the buttstock attached!

_dsf8205

The next job was to rough fit the woodwork. This is always very challenging, especially for the VSR rifles.

20161121_160152

Apologies for the quality of the pictures here, my camera was out of action so resorted to the ‘phone!

20161121_160216

This is important, the carry handle makes something like this just about portable.

20161121_163205

I bent two pieces of steel to shape by hand, two screws hold them together at the top. I will temper the steel so that it is stiff enough to hold the weight of the gun.

20161121_164521

And the buttstock is screwed into place. I will be modifying the top screw so that the stock can be folded and unfolded easily.

_dsf8350

The next few steps are to shape and finish the woodwork, screw said woodwork into place and mount the bipod, foresight unit and buttstock lock.

In the meantime, I am looking forward to getting this finished, it’s making my gun rack look comically small!

PZB-39: Build 1

Anti-Tank, Custom builds, PZB-39 Rifle, Weapons, WWII

After some extensive design work, laser cut parts and some timber start off the build!

_dsf8019

I started by bending the buttplate components. Part of this folds down to make a more compact package. I designed this with tabs and etched lines to make folding as precise and easy as possible. I could then weld the parts in place to maintain they shape and increase the strength of the parts.

_dsf7981

I then welded the inner pieces of the receiver and the buttstock hinge unit.

_dsf8020

This pivots to shorten the length of the weapon to make it *slightly* more portable, such as anti-tank rifles ever are.

_dsf8021

A piece of steel tube makes the rest of the back of the unit. It will be welded onto the top part of the buttplate. Here you can see the outer plates of the receiver in place, which stops the stock from folding up over the gun when in use.

_dsf8027

The pistol grip and trigger guard unit. In the original this is used to open the breech and eject the spent case. In this version sadly it won’t be possible to do this, but it will be used for disassembly.

_dsf8033

For the front end, the bipod unit is coming together, to keep it light and strong the legs and feet are thin gauge steel plate, folded and welded into shape. These will then be attached to the hinge which is thicker steel for strength.

MG08/15: Improved internals

Custom builds, Machine-Guns, MG08/15, Weapons, WWI, WWII

When I went to test the MG08/15 the other day out of the workshop I had one of those frustrating moments when something that worked fine in the workshop didn’t! The gun was firing groups like a shotgun at hopelessly low FPS.

I decided the issue was in a poor BB transition from the chamber to the barrel so a fix was in order to smooth this out.

Instead of one screw locking the barrel in place, which offset it slightly, I added another two screws to hold it centrally. This eliminates the step the BB was having to take to get into the barrel, causing that appalling firing pattern.

_DSF7498

A quick test run at my local indoor site proves satisfactory! Just a little tweak to the hop nub should have this beauty field ready in no time.

MG08/15: Upgraded internals

Custom builds, Machine-Guns, MG08/15, Products, Weapons, WWI, WWII

A quick video to show you what this gun shot like prior to a couple of improvements!

It was a little inconsistent, though bear in mind that this is without the hop set at all. There are several improvements that have been made since then to improve consistency and power.

Firstly, a large, stiff spring holds both the outer barrel and the hop unit in place against the gearbox.

_DSF7323

At this point, it became apparent that having quick-replacement magazines is a bit pointless as any magazine for this gun will be a high-capacity one. As a result I dropped this idea and went for the far more secure (and better feeding) fixed version.

_DSF7350

This can still be swapped between an electronic hi-cap (stored in an MG42 ammunition box, as used in WW2 with the MG08/15) and a smaller hi-cap that can be stored in the drum itself.

_DSF7353

A drum magazine lock was added to stop the drum from opening unexpectedly. The crank handle on the original was used to wind in the cloth bullet belt. It is fixed on this and the sides of the spindle hold the magazine in place.

_DSF7370

The details on the water tank, filling cap and steam hose connector.

_DSF7371

The small magazine attachment for the drum magazine. This attaches to the top of an M14 magazine.

_DSF7372

A top-up of paint to get it pretty before testing!

_DSF7374

Ready to go!

The MP28 in context

Custom builds, MP28, Products, Sub Machine-guns, Weapons, WWI, WWII

Yesterday, the owner of the MP28 came to collect his new gun and kindly brought his WW1-era Sturmtruppen impression for some photographs! The whole impression is mildly terrifying and it’s fair to say you wouldn’t want him appearing in front of you on a dark night…
_DSC5517

Although the MP28 isn’t a small fire-arm, it is very compact compared to the standard German service rifle, the G98 and even compares favourably to the K98a then in service with  advance units. Add in that the rate of fire is significantly higher than any bolt-action rifle and you have a fearsome new weapon for trench raiding.

_DSC5520

Jim has made and modified much of this uniform himself.

_DSC5526

Particularly noteworthy is the gas mask, in which he has replaced the glass vision ports with  mesh.

_DSC5528

He hand-painted his Stahlhelm based on photographs of originals, that distinctive block-camouflage was used by both sides in various forms, sometimes including unexpected colours like vivid yellows and sky blues.

_DSC5530

And of course, a vital part of any Sturmtruppen’s outfit, the spade:

“But the bayonet has practically lost its importance. It is usually the fashion now to charge with bombs and spades only. The sharpened spade is a more handy and many-sided weapon; not only can it be used for jabbing a man under the chin, but it is much better for striking with because of its greater weight; and if one hits between the neck and shoulder it easily cleaves as far down as the chest”

Eric Maria Remarque, All Quiet on the Western Front.

_DSC5533

 

You can follow the long process of building the MP28 here. This version has both a safety catch and a select-fire system built in with elevation and windage-adjustable rear sight.
