Lewis Gun: Build 2

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

At the end of the last build post, I had made the bipod legs but not the bipod itself. I designed the bipod leg mounts and assembled them. I missed out the hinge on the cut list (something has to be missed out, it’s Sod’s law) so had to hand-make them.

The distinctive bands at the front of the Lewis cooling jacket are welded into place. The rear one will also house the bipod unit made previously.

The rear sight block is another piece of laser cut steel, welded into place at the back of the receiver. I’m going to braze together the sight leaf itself together and use a 3D printed aperture to give elevation adjustment. (P.S.: Yes to other welders this weld is obviously pretty dire, I literally ran out of gas on this seam, I’ll clean it up).

The donor is held in by two screws pinching it from either side…

And a plate that will be welded into place at the back that holds under the buffer tube mount on the AEG.

I brazed together the parts for the rear sight leaf. The aperture is adjustable and is based on an ‘upgrade’ Lewis sight that gave a clearer field of view in low light conditions. The flat spring underneath locks it into upright or stowed positions.

The foresight is also 3D printed, this was by far the simplest way to get the weird shapes around that front post. This is secured by a screw and will be painted up to match the rest.

The buttstock is quite a simple one, secured by machine screws running through from one securing tang to the other. Once shaped it will be stained and finished with hardwax oil.

At the front end, the 3D printed cooling fins have arrived. They fit well, once painted up they will serve very nicely for the detailing purpose they are designed for.

Painting up and assembly under way, I have to touch up a couple of areas previously missed.

Once painted up, you can appreciate the sinister, gaping mouth of the cooling jacket.

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.

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.

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

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.

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.

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.
