Blohm und Voss P.212.02 - part 04

I can't believe how slow my progress is!  I must pick up the pace one way or another...

Anyway, here's what I have so far.

First, the nacelle at the wing tips.

If you recall from my previous post, the nacelle was a bit 'fat'.  In fact, it looked more like a fuel tank!  According to the 3-view diagrams over at the Luft'46 site, the nacelle should have been 'flush' with the wing tip.

And so I labored for many hours trying to find the best way to make the nacelle fit the open edge of the wing tip.

And here's what I got:
So far so good!  Much better than the previous design.  Most of the time spent for this was to align the segments of the nacelle with a corresponding segment on the wing.  Doing this will help Metaseq produce a cleaner result by the time I do a boolean operation (Wing minus Nacelle).

Now my problem is that the nacelles are a bit on the narrow side.  Almost like landing gear struts.  If this ends up being hard to assemble, I may bump up the scale to 1:32.  For now, I'm sticking with 1:48.

Next, I spent the rest of the weekend making the formers:
The fuselage formers (yellow) were relatively straightforward to make.  Unfortunately, I can't say the same for the wing formers.  The wing formers required a lot of work.  Due to the dihedral of the wing, I couldn't just slice away with the knife tool to make the spars.  I had to do some basic trigonometric calculations to derive the wing angle.  Once I got the angle, I created a couple of plane primitives, which I then tilted to intersect the wings at 90 degrees.  After that, I did a boolean operation to intersect the tilted plane with the wing to produce the cross cut which would later be used to make the spars. 

Boy... I guess my high school trigonometry class had some use after all! Hehehehe.
