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.

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.

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.

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.

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.

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.

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.

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.
