I had a bit of a kip, which gave me a "second wind" and eased the tenderness in my hands and wrists, so I bashed on with the resin cowlings.
After further test-fitting, I decided to remove the flanges, on both sides, from the rear of the upper cowling sections and, after further trial-fitting, this indicated that the joints would be almost perfect, although still with a very slight discrepancy on the inboard side of each cowling part.
The kit nacelle edges, and the corresponding edges of the resin parts, were lightly sanded, and test-fitted again. This indicated that the slight gap on the inboard, vertical joints, was probably due to the resin castings, perhaps "flex" of the resin, or maybe slight warping but, being on the less visible inner edges, I wasn't too concerned about this, being already prepared for at least some filling of joints.
The instructions with the "Brengun" resin parts show that the upper and lower cowl sections should be assembled
before attaching to the kit nacelles, but I reckoned that the weight of the complete assemblies would cause problems, possibly pulling the whole assembly away from the nacelle whilst setting.
Therefore, the upper cowling sections have been attached first, and the shallower, lower sections, will be attached once the main sections have fully set, and all joints filled and sanded as required, and any other remedial work carried out.
To allow some "wiggle time" for attaching and adjusting the parts, two-part epoxy adhesive was used initially, allowing this to part-cure for around 2 or 3 minutes, before locating and aligning the resin parts. Although this was possibly the correct course of action in this instance, I found it a bit messy, and couldn't really see any advantage, although the joints were also going to be reinforced with a bead of CA anyway.
As it turned out, the second ( port ) cowling was attached just using the CA, treating one surface at a time, aligning, and then repeating the process until all mating surfaces were done, and this worked just as well.
Although, as mentioned, the test-fitting showed almost perfect joints all round, when the adhesive was applied, and the parts joined, this was not quite the case, probably due to the aforementioned flexing or warping, and some adjustment, and extra adhesive, was needed until things looked at least reasonable.
So, the main extended cowlings are now in place, although, at the moment, the joints look a little messy, and will require some clean-up, a little filler here and there and some sanding, and possibly some re-engraving of the panel lines, but overall, I think they will pass, and I'm confident that the finished result will be fine.
Pics below show how things are so far, and I hope to get the clean-up done, and the lower sections fitted, sometime tomorrow, and then plan the construction of the fuselage, cockpit etc.
Thanks again for your interest and kind comments. and I'll be back with another up-date tomorrow ............... er, much later today ( doesn't tempus bl**dy fugit when you're modelling ?!!! ).
