Fuel Tanktank height is padded with 1mm wafer (actually two .5mm panels -- I didn't have any 1mm styrene sheet):
shallow holes drilled into wafer to aid gluing in upcoming step when PE panel is applied:
meanwhile, 2x parts F1 are fitted into .9mm holes in bump on top of tank...
And you need to cut out the exquisite floor piece, H1 now. Once cut from the block and cleaned up, it should look like this:
We need to fit the fuel tank temporarily into the fuselage:
...and set the floor piece on top of it...
... in order to mark the position of the large holes, which is done with a 2.5mm bit, by gently turning just a few times.
At the positions just marked, 1.8mm holes are drilled to just .5mm depth:
...and 2x parts F3 glued in:
The PE "appliqué" is glued on the bottom of the tank:
And finally the resin sump part F2 is added to the bottom of the tank:
I'll add the straps and buckles, which are provided as PE parts, when I get closer to installing the tank.
