Kar98k: Build 1

Custom builds, K98k, Weapons, WWII

Now, this is a build I’ve wanted to do for a while. Having found a keen customer who had all the parts it is now nicely underway!

This is a VSR-based build, the most practical option for a spring-powered bolt action rifle. I’m using an original stock which will be modified to take the new parts. You will be glad to hear that it isn’t a WWII period stock so far as I can tell.

_DSF9191

The action dropped in fairly easily, a square cut for the fore-end, the back being scooped out carefully to fit snugly.

_DSF9202

A view inside.

_DSF9204

The barrel, naturally, goes through the barrel recess.

_DSF9205

I then chased out part of the fore-end of the action recess all the way through the stock for the magazine well. The one slight faff with doing VSR Mausers in this way is that the faux magwell meets the real one but this is not a major issue as I’m expecting to make a new faux magwell from scratch.

_DSF9206

The outer barrel is a piece of ERW tube, which is the perfect size to use the original fittings. This will be cut to size closer to the end of the build.

_DSF9348

The VSR based rifles are still experimental at this stage, I’ve produced about four or five different magazine catch designs which I am putting into different guns for customer feedback.

_DSF9349

I’m very please with my rear sight design for this build. 3D printed, once painted up this will really look the part and gives the user elevation control.

_DSF9363

Best of all it will fit snugly onto the receiver with minimal faff. It would be nice once my casting setup is complete to make this in aluminium.

_DSF9364

On the rifle with its Uncle the G98. What you can’t see is the TDC hop mod which is part of the sight unit. This disposes of the rather finicky and annoying side adjustment arm that is the weak point in a normal VSR system.

_DSF9375

There’s still a good bit more to do on this rifle, but the framework is all there. It’s really, really comfortable and I can’t wait to get the bolt handle in place along with the last external parts and start shooting.

M2 60mm Mortar: Build 1

Area-effect, Cold War, M2 60mm Mortar, Weapons, WWII

The project started with a good deal of research, finding pictures of all the component parts. From this I calculated dimensions and drew up plans.

The M2 is quite a bit more complicated than the SMBL 2″ used by the British. For my flat laser cut parts, I’m looking at around 3x as many pieces: plus a number of cast or printed parts.

Screen Shot 2017-06-19 at 15.08.39

The baseplate is the first component to be assembled. This heavy plate is designed to stick into the ground to control and direct the recoil.

_DSF9085

Then the feet for the bipod legs and the hinge parts, Although the M2 is complicated, it does fold down quite tidily, which means a lot of moving parts.

_DSF9124

With the legs in place, the mortar starts to take shape. The tube through the middle will have the elevation control going through it, at the top of it will be the T-piece where the windage adjustment will sit.

_DSF9159

The thread arrived, it is a 20mm trapezoidal threaded rod which should be coarse enough to allow quick adjustments to be made, but fine enough to allow for accurate fire adjustment.

_DSF9259

The elevation adjustment screw in place and the T-piece at the top of the column (where the windage screw will go). There is a slit in the back of the column in which a screw sits that locks the inner column into the outer and engages the screw thread.

_DSF9302

When the elevation is raised to maximum, you can just see the thread through the slot at the back, but this will effectively be hidden by the barrel.

_DSF9303

 

The next components will be the windage adjustment and endcaps. These are going to be 3D printed in ABS for strength and will also have the barrel clamp.

Lanchester MkI*: Complete

Complete builds, Custom builds, Lanchester, Products, Sub Machine-guns, Weapons, WWII

So, the Lanchester is finished! And I am in love, though I say so myself.

_DSF9334

Details, the new magazine well closely resembles the original and is an improvement on the Sten original. I have brazed the mag catch head so that when it wears it looks brassy.

_DSF9335

The foresight and bayonet lug. This should take a rubber SMLE bayonet if the owner decides to do so!

_DSF9336

The trigger is set back, the pull is a little unusual but not bad.

_DSF9337

The buttplate, steel, though a brass SMLE buttplate could be substituted in here.

_DSF9338

The rear locking lug is just for looks on this. A hinge is quite hard to do but may be doable in the future. For now you can remove the lock and back cap to replace the battery. Unfortunately the wrist of this stock is too slim to drill through to a larger battery compartment in the buttstock.

_DSF9339

Lewis Gun: Build 1

Custom builds, Inter-War (1918-1939), Lewis Gun, Machine-Guns, Weapons, WWI, WWII

The base gun for this build is an M4. Nothing too fancy, but with lots of options for upgrade parts if needed. The first step to making the transformation into a Lewis is to build the receiver. I have modified plans I was given some time ago to build a replica to take the donor and be made from steel.

_DSF9122

Inside this I will fit a ‘harness’ to hold the donor.

_DSF9123

The drum magazine, on this I’m not sure if it will be functional, but it will be removable so I may do a very high capacity magazine in the future.

_DSF9126

The external detailing is welded on.

_DSF9127

I designed this spacer to mount on the rails, there are two of them to steady the barrel shroud.

 

_DSF9256

Dry fitting the parts, you can see the space where the rear end of the cooling fins are to go.

20170615_153236

I’m also making use of 3D printed parts for the taper on the fore-end. This part was simply much too big to make on the lathe and this system keeps the cost and the weight down.

20170615_155354

The bipod is the next major component. It will need some feet, and hinges made up for the top, which will have to come in a later instalment.

_DSF9296

Also for the next instalment, the design for the back of the cooling fins is complete (a long day’s work making this!) and it will be 3D printed much like the spacers before being painted to look like aluminium. It may even be a project for the new furnace.

M2 60mm Mortar: Introduction

Area effect, Cold War, History, M2 60mm Mortar, Weapons, WWII

The M2 Mortar was a US light service mortar designed for close support by infantry at company level. These filled the gap between hand grenades/rifle grenades and the larger (81mm) M1 used at battalion level.

"Members_of_a_Negro_mortar_company_of_the_92nd_Division_pass_the_ammunition_and_heave_it_over_at_the_Germans_in_an_almos_-_NARA_-_535546

The 81mm mortar in use with a mortar company of the 92nd Division.

It has its origins, much like nearly every modern mortar, in the WWI-era Stokes design. It was smoothbore, drop-fired and used a bipod/baseplate system.

Doughboys with the WWI Stokes mortar.

Light mortars of the inter-war/WWII period fell into two categories: The first were simple, tubes held firmly by the user when fired and aimed by direct line of sight (such as the British SMBL 2″ and Japanese T89). The latter were complex, with coarse thread screws or other systems to control elevation and windage for very accurate controlled fire.

usmortaritaly

The M2 fell into the latter category, with an attachment for a sight that could be used for both direct and indirect fire. As a result, it could be used accurately at close to its maximum range (nearly 2,000 yards).

M4-Mortar-Sight

The sight used for the M2.

Post-WWII, the M2 served in Korea and numerous Colonial conflicts with the French, finally in Vietnam. The Chinese also locally produced their own copy. It was eventually replaced in 1978 by the M224 which is still in service today and increased range capacity by about 1/3rd.

 

You can see some footage of the M2 in action here:

The Airsoft version currently being built will fire TAGs and moscarts, with a possibility of using TLSFX shells as well.

 

 

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.

First casting attempt

Tools, Weapons

OK, for those who have followed Vintage Airsoft for a VERY long time you will remember a couple of years back I built a kiln to try making some cast aluminium parts.

 

I have been trying to get my new version ready for use recently and have at last had my first casting session with it today. As many of you will know, I cast a lot of products from silicone moulds. I used one of these to make a wax copy of a 3D printed bolt. 

 

To this I added vents and a pouring spot. I made a bunch of these ready to do a batch of pours.

_DSF9301

These are contained within plaster moulds.

In these went into my mini oven for several hours. This has two purposes: 1. It melts the wax out of the plaster. 2. It dries out the plaster, forcing the moisture out of it. If there is any moisture left inside this can turn into steam instantaneously and crack the mould, possibly even a small explosion.

_DSF9304

As the last half hour came up I started melting the aluminium. 

_DSF9306

And then poured it into the moulds.

_DSF9308

And left it to cool…

_DSF9310

Once they cooled down, I broke them out of the moulds. 

_DSF9314

And the rest. These aren’t up to scratch for use but I am quite happy with them for a first attempt.

_DSF9315

In order to make more useful castings I think I will need to make more vents and pour the metal at a hotter temperature. I may experiment with some other casting materials and investments.

Lewis Gun: Introduction

Custom builds, Inter-War (1918-1939), Lewis Gun, Weapons, WWI, WWII

Before I go any further, if you are seriously interested in the history and workings of the Lewis gun, check out C&Rsenal’s video. If you just want a quick overview, you can skip that and carry on reading…

Issac Newton Lewis, Colonel, US Army designed his machine gun in 1911 and spent around two years banging his head against a brick wall trying to persuade the US Ordinance Department to adopt his gun. In 1913 he left the United States and set up shop in Belgium where he received a respectable first order from the Belgians. In 1914 BSA bought a license to produce it and as war loomed Lewis moved his factory to Britain to keep it out of German hands. Lewis’ BSA license proved very profitable: between BSA and Savage Arms around 50,000 Lewis Guns were produced by 1918 and the license granted him commission on every one made.

The design itself was based on work done by Samuel Maclean, but between Lewis and designers at BSA it was transformed into a reliable and easy to produce machine. It is gas operated, open bolt with three locking lugs at the rear of the bolt. The most distinctive feature is of course the massive aluminium heat sink/fins/barrel jacket arrangement.

Shot of the Lewis receiver. On the right you can see the barrel jacket and the rear end of the cooling fins. On the bottom of the gun, forward to the trigger is the clock-type main spring.

The idea of this was to wick heat away from the barrel as quickly as possible (quick-change barrels weren’t really a thing yet). The large mass of aluminium took the heat into the fins and the muzzle blast would suck air through from the back towards the front. In theory. In reality the necessity of this sophisticated arrangement is dubious, aircraft Lewis Guns were pressed into service on the ground during WWII, even in North Africa and the guns were found to function perfectly well without.

The magazine is also worth mentioning, coming in 47 and 97 round versions. This Pan magazine is NOT a drum magazine (which relies on a spring to feed, keeping ammunition aligned with the bore) and is manually rotated and indexed as the gun operates.

lewis8

The indexing system for the Lewis. If you want to know how it works, see the C&R video above for the animation.

Last but not least, the mainspring is a spiral clockwork type, mounted in that distinct protrusion from the belly of the receiver. This is very efficient and saves space over a much larger conventional mainspring, also allowing for easy adjustment to account for field conditions to make for reliable firing in all weather.

 

The Lewis gun’s service was long and varied. Before even leaving for Europe, Lewis had put the gun on a Wright Flyer and as a result it has the distinction of being the first machine-gun fired from an aircraft (1912).

During the Great War, Britain used them extensively, eventually outnumbering the Vickers by about 3:1 in spite of being more expensive. That the government was willing to spend so much more on these than an established home-grown piece is a comment on the quality of the design.

Due to its light weight, the Lewis was readily adopted by Air Arms where it was widely used for observer’s defensive guns. It was also mounted as foreward firing guns but had to be mounted outside of the propeller’s arc due to firing from an open bolt (therefore being nigh-on impossible to synchronise to a propeller).

By the Second World War, the Lewis was outdated for the role in which it was originally used. After Dunkirk and the fall of France, Britain pulled its Lewis guns out of reserve where it was used by the Home Guard and for low-level anti-aircraft fire. In the Far East it served with Empire forces on the front lines. Throughout the war it remained in use with the Navy and RAF for air defence from boats.

 

As well as versions chambered in .303 British, there were Lewis guns made in 7.92 and 7.7 Japanese rimmed, the Japanese having copied the design from versions captured in the Far East.

 

The Lewis had some limited influence on other designs, the FG42 taking inspiration for its bolt/piston arrangement and from that the M60. There was also a Lewis pistol, which fired from an open bolt.

Kar98k: Introduction

Cold War, K98k, Rifles, Weapons, WWII

After the Great War, the Treaty of Versailles (TofV) put strict limits on the number of weapons, ships and small arms. Germany, like all the major powers, had learned that short rifles were every bit as good as a long rifle for any realistic infantry use and frankly better in any situation other than firing in ranks.

As a result, they disposed of a lot of their G98 long rifles, keeping hold of far more Karibiner 98az models, though producing the so-called K98b (which was basically a G98 with a tangent rear sight and turn-down bolt) during the Weimar years. How many ‘b’s were produced is uncertain, but they don’t feature in pictures of the period.

During the inter-war years, levels of tolerance to the TofV fluctuated, with many civilian hunters and paramilitaries reluctant to give up their beloved weapons. As a result many were hidden, coming out of the woodwork to fight street battles between Communist and Fascist militias, the militias and the government and eventually into service with some government units.

K98k, with laminate stock.

In 1934, the German Army ordered a new design of rifle. The reasons of this are not entirely obvious, but given the timing one could conclude that it is related to: the re-armament of Germany and therefore standardisation on one rifle for all to simplify production and logistics. It would also allow for the removal of the G98/K98b from regular service and finally push those pesky long rifles to the reserves.

 

With this short rifle as standard, the Germans also standardised on the new s. S Patronen (previously used for machine guns) which produced less muzzle flash in the shorter barrels.

 

Early K98ks were blued, with walnut stocks, though changes were made to this as it went through its service life. Over time, laminate stocks were introduced, which were cheaper and required less processing time for the timber. Oak was used as a stand-in from 1943. Parkerisation was used to finish the metalwork on later models, making for a much hardier finish than traditional bluing.

The K98k is one of history’s iconic sniper weapons. Many were equipped with the ZF39 scope (pictured) and these were preferred by ‘true’ snipers.

Most famously, the K98k was the standard German rifle of WWII, but it was also used by Sweden and captured units by the USSR to fill gaps in their own equipment.

Later in the war the ZF41 scope was also issued. This clipped onto a mounting next to the tangent sight and could be removed quite easily. At 1.5x magnification it was unpopular with snipers and had a fairly poor field of view but it did allow sharpshooters to perform something of a Designated Marksman role as it would be called in modern parlance.

Post-war, it saw service with the Viet-Minh/Viet-Cong (Soviet captures sent as war aid), Korea, France, West Germany, Norway and Yugoslavia, all with their own local modifications. They also saw action in Palestine, where they were used against Arabs and British forces. Even in the latest Iraq War and following insurgency they were being used against Coalition Forces.

Participants of the Haganah revolt against British control of Palestine carry K98ks and a Sten MKII.

This really is just to scratch the surface. The K98k and its Mauser brethren went everywhere and did everything, much like its sister bolt-actions of the era well outlasting standard military use to serve in specialist roles even up to today with some armed forces. This is not to even mention civilian use.

 

Vintage Airsoft is currently working on a VSR-based K98k and will be posting the build to the blog as it progresses.

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.
