Hi welcome to my first instructable on how to create a Lego manned blaster cannon. hope you enjoy.
Step 1: The Barrel
Attach the cylindrical piece to the grooved cylindrical piece. Slot the technic pin into the normal cylindrical piece and volá the barrel is created.
Step 3: Body
Slot together the droid arm,2 black hand guns and a one by one with a loop. Connect all the parts together and you have a new piece of defence. By the way this model is fragile and should be used for display purposes.
