Not a huge amount of progress this week. I have spent a lot of time trying to get the 12 individual exhaust stubs to look right.
First up I set up a really simple jig using blue-tack (or what-ever they call the white version...) to hold the stubs in place whilst I CA glued a piece of brass rod to the back side. It all looked great until I offered the assembly up to the fuselage, only to realise that the fuselage curves (doh!!!). Every attempt to apply a curvature to the rod resulted in the stubs just breaking away, so I had to come up with an alternative that was more flexible and forgiving. If you look closely at the second photo where the stub outlets are visible you will see where I had to recreate the stub outlet as the piece was slightly short-shot in the mold making it look malformed. I added a tiny thin piece of styrene and shaped it by hand - its a bit wonky but I can live with it at this point, I certainly don't want to redo it as it took too long.
Meanwhile, I also found that one of the stubs was really badly molded. It was so bad that I had to completely reshape the whole stub using one of the others as a template. It turned out all right but it was just another really fiddly thing that needed to be fixed, chewing up a lot of time I didn't really have to spare.
My final solution to the stubs was just using styrene rod. It gave me the flexibility I needed with the added benefit of being melted together to each stub using thin styrene glue. They are not breaking off the rod this time. Whilst on the job I also noticed that there is a rod or tube that runs between the 4th and 5th stubs (counting from the front). I assumed this was a "balance tube" of some type and it doesn't appear to be on all aircraft. It's not noted in the instructions but it is shown on the box art - so I added some very carefully crafted rod to both sets of stubs. Finally I added some brass pins to the stubs so that the joining to the fuselage will be a positive fit, allowing a good anchor should some of the other stubs need a bit of gentle persuasion to fit into place. I think it should work out OK.
The next job is to get these stacks painted and, once dry, fitted to the aircraft. I've been carefully checking on a lot of the other small/fiddly pieces that will need to be fitted to finish this one up. Some of them are OK, but some, like the elevator tab actuators, will need to be completely scratch built as the kit parts are grossly out of scale and shape.
I'm hoping to get the stacks painted tomorrow - all being well. I've got a 2 hour run to finish in the early morning and hopefully I won't be too knackered to splash some paint around.
Thanks for dropping by, cheers!!
