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.
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.
The external detailing is welded on.
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.
