Agree with Mike,
Remember the big picture. Once the sidewall is complete the eye will see a sidewall that is true to the Mustang.
Once the cockpit is complete the eye will see an amazing feat of scale modeling. And once the entire model is complete the eye will be far and away too busy to see a fraction of a millimeter of difference between the width of some support struts on your currently unfinished sidewall panel and that of an original that they have never seen or at best only glanced at once..
We all seem to struggle with this - the decision point on what we can and cannot accept in our own handiwork. In the end I try to limit myself to a maximum of three reworks per project. Then I ask myself - does this ‘error’ or ‘problem’ draw the eye to a standstill?
If the wing dihedral is off, if the LG is uneven, if the tail isn’t square...these stop the eye and must be reworked.
For the rest of it, each builder ultimately decides where the lines are drawn.

I would say no to that. After all the effort you put into this and when it is buried into what is going to be a myriad of other things, and after all is said and done, may not be that visible. There will be enough other goodies to look at that nobody will give it a thought.

I'm constantly comparing what I've accomplished on my left side wall with the full sized article and so far, I believe I'm coming along replicating it nicely.....  Smiley

I'll admit that the vertical supports to the box appear to be a bit on the thick side.  Perhaps I should rebuild the whole left wall?

During the progress of fabricating the left side wall I kept debating with myself what would suffice for trim wheels on top of the main panel, when I had to remove the cap to Krazy Glue and that's when a light bulb came on. Its got small ridges around the circumference just like the full sized trim wheels and it was about the size I needed.

So, without further ado, I simply cut off the remaining end and Voila' a trim wheel. 

Amazing what one finds laying about the house and what one's imagination will do.

Heywoood,

Thank you for your reply and to know that I'm truly inspiring people with my posts.  It's gratifying in itself just to know that.

This is SO inspiring!!

I went very light on my P-40 interior..not because I wanted to necessarily - but because I simply cannot do this with my current skill set.

This is a clinic on how to - and it is priceless

Thank you for sharing your work flow and techniques here, SkyBoss

Isn't it always the case...we tend to make it more difficult than it needs to be!  Love your solution.  This is coming along nicely Skyediamonds...keep up the great work!

I believe the following pictures are pretty much self-explanatory.  No doubt you have that "Ahh haaa" moment on how the half circle was made.  I have to admit that I spent quite a  lot of time trying to figure that one out.  Sometimes the most simplest of things can be so complicated....  Tongue

In these series of pictures, I'm fabricating both the vertical supports and the box.  I am first sizing the vertical supports  to see how much clearance I need between the two horizontal areas.  From there I can also determine the size of the box.

The last picture shows the plastic sheeting in the punch and die set for the cutout of the half circle to the box.

Alrighty,

Now we're back on pace.  Sorry about that.

From comparing the left side panel of the full sized Mustang to the left side wall that I just placed inside the fuselage for viewing, I'd say I'm doing a fairly decent job of replicating the real deal.

Actually, I'm seeing if the side panel clears the floor fuel gauges.  On the real aircraft, they come very close. 

I can almost hear your thoughts on how I'm going to tackle the box with the half circle cutout, that little "baggy"  and the curved vertical member.

Okay guys,

I got ahead of myself and skipped some of the steps I took to get to this point of detailing the main panel and some of the internal vertical and cross support members.

To get the crisp folds, one must carefully score the plastic sheet just enough to bend it along the score line.   The plastic sheets I used are extremely thin. 

From there, I used a dull needle and small hammer to gently tap the rivets from the backside to have them protrude out in front for the small curved access panels.

Looks easy, doesn't it?  It really is that easy.... honest. 

However, in my excitement, it's not without its perils.  I'll get to that in just a few posts from now.   Suffice to say, it's the ease of this method of fabrication that can lull one into a false sense of security and become hasty.

I've found over the years that to achieve crisp corners and flat surfaces, use of plastic sheeting is the way to go.  The following photos really show off how the main housing came together.
