Thanks Andy.
Wetting them slightly may help with the 'drape', but once 'crunched' up and then straightened, they are a lot softer, and conform reasonably well.
The HGW instructions suggest a coat of matt varnish once assembled, but I presume this is to neutralise any 'sheen' from the surface.
I actually secured the free ends of each belt with a drop of 'Superglue' as they tended to want to lift just a little from the surface, where in 'real life', the weight and any buckles would make them hang, resting against the seat back, or lie on the seat pan. Once set, natural-looking folds or curves can easily be arranged.
I might yet give them a thin coat of acrylic paint or water colour, as the shade of the belts looks slightly pale for an earlier Sutton harness, especially given the age of the aircraft at the time depicted, when they would probably have been even darker due to soiling from use.
Anyway, on with the progress report.
PIC 1. After adding the buckles to the main section of the shoulder harness, it was taped to the cutting mat to prevent it moving around whilst fitting the 'pull down' adjustment straps, which had to be fitted at the top of the darker section with the printed representation of the adjustment grommets, and then the buckle was slid down the main strap and secured to the top of the very short 'adjustment' strap, the latter having a tiny PE 'end cap' on the end of the strap - a very fiddly exercise indeed, despite a magnifying glass, and especially with crippled hands and 63 year old eyes !
PICS 2 to 4. The harness in place, and the seat and seat frame attached to the cockpit frame. I cheated a bit here, and omitted the tiny lanyards and release pin and cone, partly due to their very small size and the difficulty and discomfort that would cause attempting to cut, assemble and fit them, and partly as I thought they'd be tricky to 'drape' convincingly, and probably wouldn't be seen anyway, once the fuselage was joined.
The same is true of the smaller 'Y' strap, which attaches to the bottom of the seat frame at the rear, where I omitted the mounting plate, which wouldn't be seen anyway, and attached the belt directly to the center frame instead, to allow more 'leeway' when arranging the belts later.
Note that this section of the harness drapes over the back of the seat, and not, as seen in some instructions and on many models, through the lower slot in the back of the seat.
The 'tail' strap has yet to have the Bowden cable shackle and cables fitted, which will be made from either a spare piece of PE, or fabricated from plastic card, with the cables from stretched sprue, or maybe 'invisible' mending thread, suitably painted. Once the cockpit assembly has been fitted, the 'cables' will be routed over the cross brace of the rear cockpit frame, and secured inside the fuselage at the frame 15 location. There was often a third cable, attached to the longitudinal brace beneath the rear glazing, supporting the harness cables, to prevent the harness falling down into the fuselage when not in use, but whether I'll fit this depends on accessibility when I reach that stage !
The lap straps have been attached beneath the seat, and not to the side of the seat or seat frame, as this was a later modification on the QS harness. The earlier Sutton harness lap straps were attached to strong points on the lower fuselage structure but, as this was not possible due to the method of assembly of the model parts, they have been positioned to present the correct appearance and, as the ends can't be seen anyway, they should look convincing enough once the fuselage halves have been joined.
PIC 5. The kit instructions call for the instrument panel to be fitted to the cockpit floor but, as I still need to re-attach the 'plumbing' for the undercarriage selector, which routes around the lower frame of the panel, if the floor was fitted, access to the selector would be virtually impossible. Therefore the panel has been fitted to the starboard fuselage half, along with the rear cockpit frame.
Next step is to fit the harness cables and the undercart plumbing, then fit the cockpit assembly, position and attach the rear ends of the cables, and make and fit the longitudinal brace between the back of the cockpit frame headrest and the rear cockpit frame. Once that's all done, the fuselage can be joined.
Thanks again for your interest and kind comments, and I'll post some more soon.
