Belly tank cars


Recommended Posts

I found the tank on line from a model airplane.    It was a solid piece.    Everything else is my design pretty much.   I found the engine on a warehouse site for free but made substantial changes.    The big challenge was the sheer number of parts.   In all I have well over 100 3D files to make everything.     I will share these files if anyone is interested

If I'm able to get a printer here soon I will certainly take you up on that.

If y'all are wanting to do reasonably accurate period belly-tank lakes cars, I'd suggest investing time in some research.

The frames were usually pretty simple, as weight is the enemy...even in cars with big honking blown hemi Chryslers.

Proportions matter too.

Here's a good start, as far as reality goes, very representative of the era. 

Be sure to look at all three pages.

I hope my post isn’t too much of a hijack. I made a master to vacuum form a drop tank from aircraft parts. I believe one half was from a fuel tank and the other was from a fuselage. It’s a generic fuel tank; not a replica of a real one. I can dig out the model if anyone wants to see it. 
 

Other aircraft can be converted to land speed racers. The Pegasus 1/18 V-1 “Buzz Bomb” has the General shape of a drop tank. Take measurements and see what it equals in 1/24 or 1/25 scale. 
 

The Lindberg/AMT “Snark” missile can make a good thrust powered LSR. The airframe is round in cross-section but flat on top. Turn it upside down and now it’s flat on the bottom. It can be something like The Blue Flame, Budweiser King rocket car, or Bloodhound type jet car with intake on top.  
 

The “Skipjack” submarine is also generally drop tank shaped. Moebius makes one in 1/72 scale (IIRC. Whatever scale it is, it’s big.) It could be a 1/6 or 1/8 belly tank. 
 

In order: 1/18 V-1 parts

This will be a great resource. Thanks

I picked up this file of a 150 gallon tank today to play with:

https://cults3d.com/en/3d-model/various/belly-tank-lakester-150-us-gallons-model-kit-custom-diecast

Looks like this, straight off the printer:

IMG_5124.thumb.jpeg.420743854be0fc609cd95bac90e4470a.jpeg

Measures at around a scale 12 feet at the size I printed it at (so a touch shorter than the ‘big’ tanks, but actually bigger than I imagined one of these would be, having never seen one in the flesh…)

For anyone who’s ever interested in buying a 3d print of something that you find a FILE for, but not a vendor selling prints, Cults3d offers an option to have the items printed and shipped to you when you check out.  I haven’t used it personally, but may be of interest to any of you who don’t want to invest in a printer…

Another tank size from the same designer:

I saved this article a while back when I was planning mine. Like you said, very simple frame.

Looks great. :D

Just a reminder: the 315 gallon P-38 tank was by far the most prevalent choice for lakesters, as packaging constraints within the shell were the number one concern. Others were used, but the P-38 tank was pretty much the "just right" size.

Though this one defies that assumption.

Of course, Tom Beatty was head and shoulders above the "average" lakes car builder in terms of engineering ability and professionalism.

Just the swing axle rear suspension fabbed up from Ford torque-tubes and front UJs is evidence of that...and he was working with guys like Barney Navarro and Frank Kurtis, both racing legends in their own right.

AND...note the small diameter of the frame tubes. This little car has technical sophistication with more in common with a birdcage Maserati than the typical lakester.

On a related note, my buddy Joey was playing with making a belly tank out of one of these:

I picked one up to try it myself but didn’t mess with it yet.  His mock-up looked cool enough for me to want to try it - and these kits aren’t super expensive as a starting point…

Link to his Instagram (he has an awesome turtledeck T and a little tiny VW-based C cab truck that are worth the price of admission alone…):
