the Buzzsaw Arm, all glued together and pinned. Good as
However, I also noticed that some of the drive chain pieces
are missing from the arm.
Instead of trying to recreate such a fiddly piece, which
would be very time consuming and costly, I'm going to make
a 'chain guard' for the arm.
To be honest, from a design perspective, the chain should
be covered anyway to protect it from damage when the Buzzsaw
Arm is chopping through things.
