Assembly Tips

It is a shame all this gets hidden inside!  Oh well, it was fun doing it.

Assembly Tips

Read the instructions!  It is OK to deviate from the assembly order in some cases, just be sure to check that it is safe to do.

Test fit everything!

Most of the kit falls together just by following the instructions.  Below I'll try to point out some of the problem areas and offer some advice.

Interior

Take photos of your interior before closing up the fuselage - you'll never see most of that hard work again!

The top turret will drop in place after assembly - I'd suggest leaving it off until final assembly.  If you are like me, those gun barrels don't have a chance of survival otherwise.  I plan to do the same with the clear tail cone and broomstick guns.

Toilet: The groove in the bottom of the toilet needs to line up with both fuselage halves, mine didn't and got knocked off during assembly.  Suggestion - don't glue it in until the halves are joined.  It can easily be done through the tail opening - just don't forget to do it!  Don't forget the copy of Life Magazine.


Windows: Be sure to put the windows in before installing the interior parts.  Window Masks
They are a tight fit.  I snapped mine in and then ran a small bead of "clear safe" CA glue around the edges.  The pre-cut masks don't fit, they are too large (AM cut them to the size of the opening rather than the glass.  They will be fixing this on future releases).  Cut the masks into quarters and they'll go on OK.  The circular ones may need a slight bit of trimming / tweaking.  TIP: When applying the provided masks mix up some water and dish detergent in a cup.  Paint the part with the soapy water and dip your tweezers in the water before picking up the mask.  This will allow you to easily position the mask.  When you are happy with the position gently blot the mask with a tissue.

 

Fuselage / Wings

It is very important the the bombardier's bulkhead is absolutely flush with the   fuselage.  Also the bombardier's sidewalls must fit flush with both the top and forward edges of the compartment.  I strongly suggest gluing the compartment wall onto the fuselage and then installing the sidewalls and floor.  My parts all took a bit of sanding to get them to fit flush.

 

 

 


When gluing the compartment onto the fuselage, first do one side, let it dry, and then do the other side.

Oh, and don't forget to put the weights in before you install the bulkhead!

 

Getting that little window in under the bombardier's compartment was frustrating until I placed a piece of very low tack tape on the inside. 

It was found that the blast from the top turret's .50 cal guns caused the nearby fuselage rivets to loosen.  The solution was to install a blast shield to protect this area.  
This was not a factory installation, and not all had it, so as always - check your references.

I made the shield from  .010" sheet styrene and used my scribing tool to press in the rivet detail.

 

Blast Shield

When gluing the wing halves together, do not glue the inside seam (like I did and then have to go back with a saw).  On my kit the shape of the wing root did not match the size of indentation in the fuselage.  By leaving this seam open you will be able to add a shim if necessary to adjust the fit.

 

The wing tips have a couple of extra features that don't belong on the 'B' version.  One is the wingtip marker lights - Simply sand them off.  The second is the set of formation lights on the starboard side.  A drop of CA glue in each of them and a few swipes with a sander and 'poof', they're gone.  The photo on the right shows the corrected tip (you can still see the formation lights through the clear CA glue).  Still to be added are the 'B' style marker lights which were mounted top and bottom about 3/8" in from the tip.

The new marker light.  A drop of silver, a drop of clear red (or blue/green) and a drop of CA glue and there you have it.
 The B-25 didn't get the fuel vents on the aft end of the engine nacelles 
 until after the B version.  Carefully sand them off.

Tail

The horizontal tail assemble can present a bit of a challenge.  If you've test fitted the assembly you no doubt have seen that it just doesn't fit very well (at least mine didn't).
Here is how I dealt with it.

  1. Carefully (and patiently) sand the assembly to get the best dry fit  Pay attention to the elevators, be sure there is a gap on both inside edges where they join the fuselage.

  2. Start at the front and glue only one side to the fuselage.  To get a good fit you may need to have the rear of the assembly tilted upwards - don't worry.  You may need to use a clamp to get the forward top of of the tail flush with the fuselage.  A little bit of downward pressure will get a good flush joint.  Let this thoroughly dry!

  3. The other side of the front joint probably will not be flush.  Use clamp pressure to get a flush joint and glue.  (first picture on right)
    Once again, let this thoroughly dry.

  4. Now glue the rear top portion.  If you needed to raise the rear in step 2, a clamp may be needed here.

  5. OK, at this point you will probably have huge gaps between the lower tail and the fuselage.  Once more grab your clamp and crank it down until the gap is minimal.  Carefully paint on a liberal amount of cement and cross your fingers that it will bridge the gap.  You want to avoid filler here if at all possible since there are lots of rivets right at the joint.  If you are like me, any sanding or filling here will be disaster for all that nice detail.

  6. If you are doing a Doolittle raider - Don't glue the vertical stabilizers on!  It will make painting the the deicer boots much easier.

The planes had two formation lights mounted in the tail.  I made these by punching the circles from clear plastic.  After painting I applied a drop of CA glue to give them lenses.

Paint & Finishing


An easy way to mask those openings

I used Tamiya paints for this project.  Their version of Olive Drab is too dark and too green.  Using a color chip for 1943 OD as reference (the closest I had) I came up with a pretty good match using this formula:
5 pts Olive Drab 
3 pts Khaki Drab
2 pts White

Just about every reference photo I have shows the fabric control surfaces a few shades lighter than the metal.  After painting the OD I masked off the control surfaces and shot a lightened version of OD.  I then added more white and a bit of yellow-green and lightly airbrushed some fading and streaks on the top side of the wings and fuselage.   

After a clear coat I applied a light wash of artist oils to the panel lines and used pastels and silver pencil for a slight amount of weathering.
