I eventually got back to the PR.IX, and managed around six hours at the bench, although around half of that time was spent test-fitting, trying to identify what was fouling the cockpit assembly, preventing the fuselage halves from closing without having to exert undue pressure.
As I intend to fit the T.1154 radio transmitter further aft on the radio shelf, as it should be, and therefore allow room for the scratch-built Navigator's head armour to be in the folded position, I needed to ensure that there would be clearance, under the aft section of the canopy, this being lower than the area where the radio would fit if the instructions were followed.
I therefore tacked the main cockpit sections together, and placed them in position in the starboard side of the fuselage, so that the fuselage could be taped together, and the radio position checked with the canopy in place.
Although the main parts had fitted without problem, after cutting a notch into the resin cables along the cockpit sill, this time, with the vertical mid-section bulkhead in place, the fuselage would not close around the nose, without squeezing hard, and I noticed that the cockpit assembly would not slide all the way back onto its locating points, which seemed to be the cause of the problem.
As there is some warpage in one fuselage half, with a distinct 'bow', any other problem with joining the fuselage halves could become serious, leading to misalignment, and a probable 'step' in the joint, or worse.
After disassembling, checking, and trying again, numerous times, it became obvious that the vertical bulkhead was causing the problem - this is a part from the original FB.VI kit from 1980, along with most of the other cockpit parts, with the exception of the main floor, instrument panel and half bulkhead, and the 'bomber style' control column.
It would seem that the marriage of these parts, to the newer fuselage moulding, was not a particularly happy one, as the vertical bulkhead was fouling against the extreme rear edge of the 'map board', moulded onto the starboard cockpit wall, with the spar section, acting as the base for the Navigator's seat, not quite clearing the bottom edge of the trailing aerial crank wheel, both of these items being absent from the older kit.
This fouling was miniscule, probably less than half a millimeter, but enough to prevent the entire assembly from fitting together as it should. To be fair, the addition of the resin parts probably added slightly to the misalignment, even though corrections and allowances had been made to counter any problems.
The remedy was fairly straightforward, though time consuming, having to keep checking fit in three different areas. The vertical 'rib' of the map board was reduced in thickness, the edge of the vertical bulkhead was filed back, and the horizontal section representing the spar was chamferred, to clear the bottom of the crank wheel.
The cockpit assembly now seems to fit, although I'm still expecting some problems when the time comes to join the fuselage, due to the warped starboard section.
So, with that done, I eventually managed to make a little progress, with those ill-fitting nose windows tidied up, sealed around he inner edges, and the edges painted to try cover at least some of the untidy joints. Those areas which needed filing have been re-touched, and some wiring has been added to the resin wiring on the starboard side, leading up over the 'roof' of the nose compartment, towards the rear of the instrument panel.
The main cockpit components have been assembled and painted, and the pilot's seat has been assembled, after first thinning-down the seat pan, arm-rest supports, and the back armour, and work has begun on detailing the radio equipment.
PIC 1. A poor shot, due to the lighting and reflections, but his shows the nose windows, which don't look as bad when views through the nose aperture, and the extra wiring, leading off from the moulded resin wiring.
PIC 2. The main cockpit assembly, with the seat, control column 'boot', and Navigator's knee pad painted in a worn leather shade, and the signal flares painted, along with the fire extinguisher, again,
not red !
The camera control equipment in the nose has yet to be painted and detailed.
The pilot's seat has been thinned-down, as has the back armour, and the seat harness shackle has been thinned, ready to accept the Eduard PE pre-painted harness.
PICS 3 and 4. The Airfix T/R 1154/1155 radio equipment is very nicely done, with only a little added detail required to make them really stand out. Here, the R1155 Receiver has had the installation handles added, together with a couple of switches, the pressed panels, and some screw heads.
The underside has been drilled to accept the cables, which will be fitted later, along with the scratch-built support frame.
PICS 5 to 7. Likewise, the T1154 transmitter is a little gem, better, and more accurate, than the Tamiya example. Again, the pressed panels have been added, as have the ventilation holes in the center of the front panel, and some screw heads. The three holes are for the connecting sockets for the power lead, receiver connector, and the aerial cable, all of which will be fitted once the equipment has been painted and installed.
I hope to get the cockpit completed and installed, and the fuselage closed-up, some time tomorrow, and then jump back over to the other side of the Airframes Aircraft (1943) Ltd factory production line, and continue with the other part of the De Havilland contract !
