Title: 1/35 Halftrack Beetle
Post by: Frank3k on October 22, 2025, 11:14:01 AM
I saw this image either here or in another search:

(https://scontent-lax3-2.xx.fbcdn.net/v/t39.30808-6/494734128_1132474055563941_4784606566357375166_n.jpg?_nc_cat=106&ccb=1-7&_nc_sid=127cfc&_nc_ohc=aVPLxmxZWMIQ7kNvwF6NQyb&_nc_oc=AdnbAMAVsF-UYL8i1iggAsP9WHL2C-ecQAo9jAnNX304GaOGhVF0VikUmKhR0mL3Ja35EU5zObDJmhxNwvq8udS0&_nc_zt=23&_nc_ht=scontent-lax3-2.xx&_nc_gid=_DKB7x76LmiK1AJsWLkGdg&oh=00_AfcwHpoVaKTFf6VnysKHCLlTc3hJJSRluXNcZNnNeoNA-g&oe=68FE11F5)

It seems to be the only picture of this vehicle online. A scale model was built here (https://www.wettringer-modellbauforum.de/forum/index.php?page=Thread&threadID=74859)

The vehicle seems to have used the front of a VW Beetle and the tracks and engine from a Kettenkrad.

I have an old kit of the 1/35 CMK Type 82E VW Beetle (https://www.scalemates.com/kits/cmk-t35014-volkswagen-typ-82e--112523) in the stash - nice kit for the era, but there are better models now. I also have the tracks from an old Tamiya Kettenkrad. I figured that I could combine the two into a larger pickup style vehicle and imply the use of the original Beetle engine, with the Kettenkrad drive wheel driven by the Beetle's rear axle.

The CMK is pretty simple and well molded and the basic surgery went well. I 3D printed an ABS core for the rear and added parts from my junk boxes to fill out the rear section. This is where I am right now. Most of the parts are tacke don right now. I scratchbuilt an engine air intake:

It may be a bit long and impractical, but I'll see how far I can take this.

This is getting off to a great start with the extended bed.  I am guessing that the vent on the cab rear wall is providing the cooling air intake to the engine?  Looks like there will be plenty of room under the flat bed for a fuel tank and all of the OVE/OVM to be stowed.

Such a clean work area! The sign of a deranged mind! Just the sort of guy we need!
You could paint the beetle body some bright color and the back half left over military colors with lots of rust and dirt.
This is going to be very cool!

Post by: Frank3k on October 23, 2025, 05:02:42 AM
It's a new, clean cutting mat. I moved all the debris out of the frame.

Jeff - that is the cooling intake for the engine!

I'm printing a shorter version to see if it looks better.

Frank, I don't know how far you've gotten on your mod's but how about;
1) reducing the gap at the front of the tracks to about half;
2) making two engine air intakes that go either side of the rear window (about half the width of the current one); &
3) move the cargo tray forward to the rear of the cab, or with a much smaller gap (say 0.5mm), the air intakes could drop into the top of the tray* with a toolbox between them &, possibly, a steel-tube-&-mesh barrier behind them.

 ???



[*: The air intakes would cut across the top of the track-well below the level of the tray.]

Nice take on this. Be interesting to hear the VW engine whine along with track rattle

Yep. This is a very cool concept, Frank!  :smiley:

I repiled on Whatif as well -  Most of the dimensions and position are set by the rear axle and the engine. I'm trying to keep the VW mods to a minimum; some farmer needed a vehicle with more grip in the field; he had an old VW and found a broken Kettenkrad and mated the two.
This is what I printed today. Everything is tacked on and the tracks on the other side aren't even on. Modifying the two tracks was easy - the old plastic was the biggest concern. I think it looks a little better now.

There's storage space on top of the rear box, plus about half the volume under it (from the overlap of the two middle wheels to the rear). Plenty of room for cargo. I'll probably add mudguards, which will add some storage space as well. Something like this:

Personally, I think it looks much better now! On that first original picture I don't know how anyone got in or out.

On that first original picture I don't know how anyone got in or out.

With only a little difficulty I think - a Kombi has the same door shape (tho a little larger).  I expect that farmer had some troubles with the vehicle as Ferry Porsche found with the tracked Kübel (not powerful enough to do much due to the drag in the trackwork & ineffective brakes)  ;)

How likely would it be for a farmer in Western Europe (ca 1946-1950) to have a welder? It's either welded joints or bolted (or maybe both) for the mods to this one.
Title: Re: 1/35 Halftrack Beetle
Post by: Jeffry Fontaine on October 25, 2025, 10:26:54 AM
Maybe access to gas welding rig with bottled oxygen and acetylene and some metal rods for brazing the parts together?
Title: Re: 1/35 Halftrack Beetle
Post by: Kerick on October 25, 2025, 10:43:59 AM
All you would need is the blacksmith in the village to do the parts.
Title: Re: 1/35 Halftrack Beetle

After the German retreat many repair troops would have abandoned their kit.

Post by: Frank3k on October 27, 2025, 10:07:27 AM
Thanks for all the ideas! The French/Belgian/Dutch/German/Italian farmer collected broken down vehicles and parts, drew up a sketch of what he wanted and took it to the village blacksmith, who had access to recently liberated welding equipment. For a small price and exchange of goods, this was the product.

I skinned the 3D printed ABS skeleton and added some details. This is what I have so far (just needs a few more bits before painting). The green shackles are from an ancient RPM FT-17 kit:

(https://live.staticflickr.com/65535/54881448747_2151d27798_b.jpg)

The two hinged hatches are for engine access (with the handle) and for general storage at the very rear:
(https://live.staticflickr.com/65535/54882316811_dd5f185a1e_b.jpg)

I also printed some very thin ABS sides to represent either plywood or fabric covered sides. The front wall closest to the cab would have prevented the engine hatch from opening fully, so I modified it (rather than reprint). :

(https://live.staticflickr.com/65535/54882316836_3378f52806_b.jpg)

I'm not sure if I want to use the sides. The rear hatch would swing to the side to allow access to the rear cargo hatch.

Too true. Although, in Frank's original DIY farmer scenario, it would also be a handy little hay-hauler on smaller plots.

Although I'm liking the forestry angle as well. It would go with the Waldschlepper RS 1500 (https://beyondthesprues.com/Forum/index.php?topic=11057.msg217747#msg217747)

Almost done! Just need a couple of things (like cargo). The chains are thin bass chains. They were not easy to install. I also added latches to the rear hatch and red lights to the rear, but they aren't visible. The vehicle is slightly rusty:

(https://live.staticflickr.com/65535/54895455261_67e4d0e4c5_b.jpg)

The fire extinguisher is one I designed and 3D printed a while ago, It's actually a reject, but I made it work. The driver's side window is down and the side view mirrors are scratch built. I flipped the cargo panels around, with the metal framework facing out. The panels are (I'm assuming) either cheap, rotting plywood or some sort of dense, painted weave glued or bolted onto the frames :

(https://live.staticflickr.com/65535/54895755120_5fc6ef1ea9_b.jpg)

All the clear parts in this kit are thick and have whorls from the injection molding. It took a while to polish them out. Of course, the affected areas are under the dust...

Thanks guys - it's been a pretty stress-free build. I reduced the stash by one old kit and the junk box by some loose Kettenkrad bits. The old CMK kit isn't bad, but it just doesn't compare to modern kits, like the Takom.

Looks great :smiley: The FDM striations on the bed actually add a nice texture for once instead ruining the look of the model.

Post by: Jeffry Fontaine on November 03, 2025, 04:20:21 AM
The shortened track made a real difference in appearance on this.  The proportions are much better between the cargo bed and VW body and it has balance.  Which ever choice you make on purpose is going to be a winner!

I like that car arrangement!

I'm calling this one done. I added some generic tools. The French Mechanic and Jeff Bezos are discussing the work required in the field/forest:

"Mssr. Bezos, T'es un connard insupportable, tu sais?"...

C'est vrai!  ;D

... I don't know what bellend translates to in French.

Probably extrémité de cloche isn't what you had in mind  ;)

In slang, tête du noeud is virtually identical to bellend - referring to the glans or to an imbecile.
