Just had a couple of minutes to pop over and have a look at the GB45 build by
Wayne Little
- wow!! Would love to think I could work at that standard, but will continue on (
mumbles quietly to self... ).
Got some intermittent bench time over the past week or so and managed to get the wings assembled. I did run into a few issues here, mostly with top wing panel alignment. I don't think I created this problem (at least I cant see where I would have), but when offering up the top panel I noticed on both sides that the top wing was about 0.5mm forward and about 0.25mm outboard of the lower wing. I fussed around with the fit, finding that the wing spar pieces attached to the lower wing when "keying" into their top wing positions pushed it out of whack. I ended up shaving a small amount of plastic from the spar ribs and got the wing to about 0.15mm within fore and aft and pretty much lined up laterally. The other issue this created was one of my pet hates - a gap on the trailing edges.
In the first of these two photos I hope you can see the gap and misalignment issue on the port wing. I did the usual things like shaving down the trailing edges as much as possible (without destroying the look of the wing) and chamfered plastic off the inside mating surfaces - still had a gap. So I thought - hang it - I'll just add a stretched sprue bead along the trailing edge and shape it back in to match the wing - see the second photo. I have say I am stoked with how it turned out. I was worried about how "soft" the Airfix plastic is, so I used some saved sprue from an old HobbyCraft kit which is really hard and glued that into place. Good choice. Not only did it allow me to fill in the gap, but the harder plastic allowed me to shape it into a fine edge without any issue.
From the front you can see I still had an issue with the patchy alignment, as highlighted by the arrows. The other issue I had was with warping. In an earlier post I noted that one of the spar parts was warped - turns out that the starboard lower wing panel was also slightly warped. I tried my best to pull it back into shape but I think it is still a bit wonky and I think it makes the outboard section of the starboard wing droop slightly (or maybe I am just seeing things). I couldn't get a shot of it so maybe it is just my imagination...?
From the underside the wheel well panels all appear to fit really well, I have no significant gaps or alignment issues that I can see - happy days!
The other thing I have been working on is the blast tubes (thanks again to Andy -
Crimea_River
- for the information on gun muzzles v's blast tubes). I cut some tubes from brass tube and set some styrene plugs in the ends so they can be inserted into the holes I pre-drilled in the wing spar gun locations.
The tricky bit with these was to get the wing leading edge shape correct so they wont need too much touching up once in place.
I managed to get them installed this evening - they haven't come out too bad. Some are not quite sitting as intended but I will work with them as they are I think. I did think that it would be a shame to cover them with red tape patches so the intent is to show the aircraft at the end of a sortie rather than the beginning. That way I can put holes in the tape and show the blast tubes - that's my working theory anyway...
As noted earlier, I did look at Wayne's GB45 build of this kit and have noted his comments re: fuselage to wing fit. I have done a rough test fit (without any fuselage assembly) and think I am going to have a real challenge with this. There appears to be insufficient fore/aft curvature in the lower wing panel to match the fuselage, which means I will be having fun trying to keep the whole thing clamped up whilst the glue dries. I suspect that a piece by piece approach to gluing them together might be the way to go. Updates on my plan of attack to follow.
I think that is about all I have for this post. Thanks for looking in and for all the information and guidance along the way!! Cheers.
