Thanks so much for your kind words.

One of the problems of course with a tri-cycle gear model is to get it to sit on all 3 wheels as the CG without the weight of the real plane's equipment makes the model tail heavy. I put some weight in the bottom of the nose turret and inside the nose wheel itself, but what seems to have really helped is that since the engines all sit forward of the main gear, I stuffed a bunch of washers behind each firewall hoping the fact that it was quite a bit of weight would compensate for the fact that it was only slightly forward of the gears. I'm hopeful that it will be enough.

Having an aircraft with the CG right at just barely in front of the main gear would make landings and take offs pretty tricky for sure.

Hi Tom - I've been lurking in the shadows and just want to compliment you on your beautiful workmanship . Nice to see another post - hurry up and get the basement done so we can have more !

As an aside I have watched the Collings Foundation B 24 on several occasions and have come to the conclusion that it's center of gravity must be exactly over the main landing gear as I have never seen an an aircraft hobby horse so much while taxiing . Almost made me seasick while watching !

Cheers - Richard




That's interesting, and probably shows just how bombload dependent the thing was for balance...

That's also probably why the C-87 transport was so finicky (and was almost grounded after 2-3 accidents). The bomb racks set a regulated center of gravity, but a transport could have deadly variations if you were not careful...

That makes sense. It appears the bomb bay is pretty close to the main gear (give or take) and that would help to keep the CG in the middle to forward part of the A/C.

Time for an update. While my basement was being finished (Labor Day -Thanksgiving) I created a temporary work area in my den and actually continued to get some stuff done. Most of what I did was scratch build all of the interior items I wanted to add (mostly for the intercom and radio systems) along with other details. I'll probably have to stop for a while again, while I start to rebuild my work room in the basement so I can resume work there. Next big project will be the bomb bay as well as the radio operators station and the radio installation over the bomb bay.

Exceptional detail, my mind has been totally blown. Been following this build and it keeps getting better, your a true master well done Tom

Hey Tom!

Some nice fiddly bits there!

Thanks for all your kind words. After I bought the aftermarket radio set available, I realized that there were quite a few items not included, and it seemed silly to put a few in and not the rest, so I resorted to scratch building. The internet is so great for research, as I was able to find not only the flight manual which described all the items along with pictures, but additional photos of the items from various places as well. Once an engineer, always an engineer I guess!

Tom,

I am in awe!

Splendid work. So where did you get these - scratchbuilt? I think this is a hydraulic/fuel system:

It's a hybrid. The main piece you're looking at in the photo is from the Eduard PE set with some scratch built pieces to give it more depth. There's another similar PE piece for the LH side of the aircraft. But these pieces go only in the bomb bay section, so I scratch built some additional pieces to go into the area under the flight deck. I didn't make as many lines as there actually are according to the photos, but only enough to match the PE lines.

Time for an update. I've mostly finished the intercom wiring and the radio system installation. A large part of that has to wait until after I build the compartment over the bomb bay. I've also installed the flight suit heater system and the aux generator and batteries as well as two hydraulic reservoirs and the nose gear door retractors. Next up will be the oxygen and fuel systems and then on to the bomb bay which will finally allow me to permanently install the flight deck and nose wheel assembly.

I've finished the oxygen system. Next up will be to finally complete the bomb bay which will include scratch building the radio compartment over the wings as well as do the fuel system. I won't do any tanks since those are either inside the wings (already completed) or in the space which the wing attachments are. But I plan to add the hoses, lines and valves which would either be in the radio compartment or bomb bay.

Thanks to Frederick Boucher's excellent photos I was able to figure out several errors I'd made in the rear section of the aircraft, and I've now corrected these as shown. Thanks so much for your help!

I'm still not quite sure how the roof of the bomb bay is constructed, but I'm starting to have some better ideas and hope to be able to confirm the construction details so I can finish out that area.

Here's the latest showing the corrections I've made.

Time for an update. Since my last posting I have been able to get some extremely great reference information on the inside of the B-24. A docent from The Canada Aviation and Space Museum provided me with a whole bunch of interior photos and the Collings Foundation has an incredible resource at this website: http://vintagetin.net/B-24Witchcraft/J/ which has about a dozen 360 degree camera views from all over the aircraft which allow you to pan and zoom to your heart's content.

But as a result of all the great information I realized that I had to make quite a few corrections to some of the work I'd done, so below you can see the results of that.

Originally, I'd considered closing up the aircraft completely after I'd finished (I know, but I've done this with several other models before) but I've had a change of mind. In talking with the folks over at the Yankee Air Museum at Willow Run, since they have neither a complete B-24 nor a highly detailed model with the interior, they've agreed to accept mine for display when I (finally) complete it.

This has led me to decide to leave the two halves unassembled and display the model with the two interior sides open in one direction and the exterior in the other. And that meant I had to add some additional structure to the "main" (right) side of the model to accommodate some of the additional detail.

So below are the current photos and now that I've gotten my concept down (took quite a while to figure out how to proceed) I should be able to make better progress. Maybe.

Can you explain this better? I can't picture it. How many fuselage parts are you using? Two full interiors for a separate display, and then a closed up one with the wings, etc?

Sorry if I wasn't clear. It's just one aircraft kit.

Imagine leaving the two fuselage halves not glued together. Think of an imaginary "hinge" right at the very nose of the aircraft and then pivoting the two fuselage halves around that "hinge" until they are pointed directly at each other. From one side you will see the interior of both halves, (pointed at each other nose to nose) and if you look at it from the opposite side, you'd see the exterior of both halves, again pointed at each other nose to nose. It was the only way I could figure out how you could see both the interior AND exterior of both halves of the aircraft.

Hope that helps.

Yes, I get it now. It's a very unconventional approach. I would have a hard time "going there" myself, though I see the reasoning.

Might one alternative be, if the Museum is willing to go along, 1/48 Scale photos as a backdrop to the completed, closed up fuselage?

Best,

Brian

I'd considered that, but since I've decided on my current approach, some of the items I've built in to the primary (or right hand side) of the aircraft may not necessarily allow for the two halves to be completely closed up.

Before I decided on this approach I had to be extremely careful that everything I added was able to allow the two halves to close completely.

At this point I think I'd just as soon have people be able to actually see the interior directly as opposed to the photos.

We'll see how it turns out.

Leave the left side of the fuselage off, but add the wing and stabilizer back to the right half. Then you have a standing model.

I will be adding the right wing and the full stabilizer to the right hand side, and as you say that will leave a standing model with the nose gear, right strut and the ladder going into the rear hatch.

But there is also a lot of detail on the interior of the LH side and to leave that out would mean I'd also be losing the LH exterior which is where the nose art is.

So I'm really very reluctant to not include the LH side despite the issue with how else to support all of it. I'll most likely just use some clear posts to hold it up.
