In bits and pieces overnight what to me is some significant progress was made: the blocks forming fairwater/conning tower/fin/sail/whatever-you-call-the thing-on-this-style-of-submarine were drilled for the periscope shears then stacked and glued.
Process was:
Top of top block had been marked for scope locations. New Dremel drill press was employed to drill it.
Top block was set in place on lower block, tubes for shears were inserted then twisted against lower block to mark it.
Lower block was drilled.
Lower block was used to mark deck for drilling.
--> I'm deliberately doing something here which was done by happenstance on PRS-1, the periscopes are tube and go all the way through in to free-flooding hull; as sub dives they often vent bubbles out unsealed periscope tops.
Deck was drilled.
Blocks were stacked on deck, shear tubes inserted, & thin super glue was flowed in to joins.
This assembly is going to
STAY assembled!
Oh, the open bridge and 20mm platform assembly is not yet glued on.
