Airsoft Welrod: Part 1

Cold War, Custom builds, pistol, Suppressed, Weapons, Welrod, WWII

Our long-term readers may remember a long time ago an introduction to the Welrod.

 

While the initial project was for an airsoft model, it ended up being an inert replica for the client in question. Well, the Welrod is back for another attempt at the quietest airsoft pistol around!

The base gun for this is a double-action non blow back CO2 pistol. For those of you who like the internals of guns here is a picture!

In order to keep things simple (K.I.S.S. or Keep It Simple, Stupid is my motto), I’m keeping as much of the frame as possible as it does a good job of holding the internals and designing a new frame… well suffice to say that life is short. The red coloured areas will be removed over the course of the build.

The donor with several of the red panels cut away on one side. I actually quite like the slightly steampunk aesthetic of being able to see some of the internals.

The receiver in progress, the first step is to cut out a recess for the donor.

Which, with both halves now matching, fits in very nicely. Inside the tube is a buffer that holds the front of the barrel and stops the mainspring. In theory this could be adjustable to make the barrel unit strike the valve harder/softer to control FPS. I’m not sure at this stage how feasible this would be though.

The front cap and back cap, freshly turned on the lathe! Both parts are in mild steel so will match the rest of the receiver nicely when all finished. The dip around the muzzle is to disperse the muzzle blast more effectively when used at point-blank range. Which it often had to be as accuracy was pretty appalling with the original!

The next stage is to make the trigger guard and housing unit, then modify the pistol grip.

Welrod Build Part 2

Further progress was made on the Welrod yesterday! This project is coming together quite quickly as it is already starting to look like the original gun.

Below you can see the internal cylinder pulled out as if the gun was being cocked. This also aligns the feed system for loading. The gun cocks on opening when the piston locks into the sear.

Next job is to make the piston (it will be a custom-made piston in aluminium, turned on the lathe) and the second sear. I’ll also have to buy in the barrel and the spring!

Welrod build Part 1

Cold War, Custom builds, Products, Suppressed, Welrod, WWII

Last week I collected a whole host of parts for various projects from the laser cutters, among which were the bits for the Welrod MkII.

It’s always an unnerving time when the parts come back as there’s almost always something missing or slightly wrong that you have forgotten to correct during the development of the design. In this case there was a little to-ing and fro-ing on the size of the cylinder and the guide washers that suspended the cylinder in the original deign became somewhat redundant by the time the parts went for cutting and the stop-post (that prevents the spring sliding back with the rest of the cylinder) was built into one of these. An easy enough fix though and one that will both simplify manufacture in the longer run and make the Welrod much easier to strip.

While I was waiting for the tubes that make up the shroud and cylinder I decided to make progress on assembling the groupings that make up the gun.

In this picture I have left out the spring (as I haven’t bought it yet) and the second sear (as I haven’t made it yet) but as you can see, it’s pretty simple, much like the original. There may have to be a few tweaks to the design here and there as the build progresses but so far, so good!
