Thanks for the reactions, I appreciate them.
Construction has stood still for a while due to completion of another build, but finally I made some progress last week.
I continued with the constructions on the deck
There will be four big guns on the deck, two in front and two in the back.
Finished with a fence from the lasercut set:
The same type of constructions on the backside of the deck:
There a two little guns to make, not to complicated:
And this is the current state.
Construction is going well so far.
What is striking is that not everything fits exactly.
Many parts need a little adjustment, but it is doable.
