It was mass produced in significant quantities throughout the war and you have probably seen it with the "T-Stock" in it's MkII configuration (as shown above).
However, I going to to have a go at fabricating a "Loop stock" (as shown below) for an existing reproduction Sten.
The plan is to make a 'stand off 1:1 scale' version. By that I mean it will not be an exact replica, but it should generally look like the real thing from a few feet away. This is consistent with the rest of the reproduction Sten which is also not an exact replica.
The main differences are that I will fabricate it from Aluminium rod and not mild steel 'U-section'. I will braze the joints and support with 3mm threaded rod where I can and not weld them like the original.
I'm using some 10mm anodised aluminium rod I have rattling around my workshop. I started by using the T stock that I have to give me the general sizes and set about eye-balling the bending points.
Here is my result after the first bends
When I rough cut the prototype stock from the rest of the bar and put it next to the rest of the reproduction Sten you can see I have a few adjustments to make.
Nothing to difficult to get those bends right, just a bit more heat and a bit more bending. I'm afraid I ran out of gas for my torch so I will continue this post when I resupply.
I now have more gas, read part two here.
