Now I got the elbows modified, the next phase is going to be trickier and complicated.
the needed tools are as follows:
The blade knife, plamo side cutter, cement…
The first thing I did was cut the upper part of the thigh just below the ball socket joint.
Next, I hollowed out the thigh parts to make room for the inner frame part that I’ll be scratch building later.
I borrowed the concept of the knee joints from the MG EW frame and scaled it down to match the 1/144 scale. I glued two layers of 1.0mm pla plates to create the double jointed knee, I drilled 2mm holes and fabricated 2mm ABS pegs for the double joints.
After the knee joint, I cut off the back part of the feet and the ball joint. I used the poly caps from the hip joints and transplanted them on the feet. I fabricated right angle joints for the ankles to give the feet wider swivel movement.

Ankle armor pegs are installed in the ankle joints. This is what will hold up the ankle armor in place.

Joints upgrade for the legs is complete! Now, I can make the Heavyarms do more interesting poses.
