It appears that I shall have to use 8kV 105mA for running the system
so the voltage-rating is more than enough.. and the x-former oil should
fill the dents anyway if they don't get fixed as I press the plates

That's exactly the appearance of my plastic - Great!

..and by leaving a little "empty" space to the bottom of the tank between
the bottom-plate and the cap-plates - the water should gather there because
of density-differencies..

btw: I do now have the electrodes ready for the airblast-spark.gap with
the holes in the middle of the end-faces as you described.. I'll soon
make a base for the electrodes using acrylic plastic so that the both
electrodes are fixed to the base but part of the base is mobile compared
to the other electrode - aka I can adjust the distance between electrodes
without having to touch/turn them like in your design.. They are not
of brass but bronze - I guess that is does not matter as the m.p. is higher..
