Had a plethora of extra sentinel pieces so decided to make some pieces for my X-Men figs. This is a sentinel arm that was shaped and shaved, with much of the upper arm removed. Random wires and metal fodder pieces were carefully placed and painted, with hot glue sparks on the end. I hope the illusion is that the arm was just ripped off.
like he's just ripped it from
a Sentinel.......
Excellent idea for a custom....
