A bit of a catch up on the progress.
I worked on getting the motor ESC & servo set up for the rotating platform & the raising of the cannon.
I also had to paint the barbette and the cabin before the final fitout of the cannon.
So I made a bracket from some aluminium angle to mount the motor & ESC onto.
I cut the base out of the barbette and connected the shaft of the platform to the motor/gearbox shaft with a flexible coupler.
A bracket was also fashioned for the servo that will raise & lower the cannon and fixed to the underside of the platform as this needs to rotate with the cannon.
It appears that the original ship would only raise & fire one cannon at a time. So I just connected the rear of them with thread through the floor to the arm on the servo.
When the servo is operated the cross arm would pull the rear of one of them down, raising the barrel. The other thread would just go slack as that side of the arm moved up.
Obviously operating the servo in the other direction would raise the other cannon.
Here's a few pics.
Brackets, servo, motor/gearbox, added to the underside.

Thread passed through the carriage into the barrel of the cannon.

All fitted, and also a 10A ESC for the motor.

All finished.
