Kit bashing/Scratch building is very fun, but it eats up a lot of time. You will need to glue together parts that were never meant to join, and you need to wait for the glue to cure/harden before gluing the next bit.
The parts of Mortarleg here is scavenged from:
MG Deathscythe
HGUC Z'gok-E
HGUC Marasai
Balden Arm Arms
30mm Backpack set
Various bits from Various kits
Styrene sheet and rods and strip.

It takes forever and its why I'm the slowest builder in these contests...
