Default Sd.Kfz. 251 Ausf. B - work horse of German infantry - the build report

After the success of the printed model kit of the 6-wheeled Sd.Kfz. 231, another important vehicle of German WW II armor is in development: the half track Sd.Kfz. 251

The design phase is in progress. Here are some pictures of the current status:









Some test printing took place to improve the design.





More details have to be designed (especially the engine hood and at the inside of the hull), before the first prototype will be printed.

Available will it be here soon:

Keep you updated.

Greets,
Freddy

Excellent project! I'm amazed how fast you can do the CAD work - takes me years! Are the resin prints functional parts or "test prints". I'm finding the ABS like resin to be pretty good for functional parts, esp if I make the part a little thicker than scale for strength. Following with interest! Will tracks be printed?
Best regards,
B

hmmm fast...not fast enough in my opinion; until now I've needed approx. 120 hours to get this status and I'm not finished yet.
The Resin and PLA prints are first test to see if it's correct an functional but will be improved.

There are metal tracks available:

After hours and hours of detailing, the design phase is done so far.

Some shots of the end design steps:











Workable back doors…









Coming up, the printing of the first prototype.

That looks amazing so far. I know of a few of my local crowd that would love one of these, and a -D for a PAK 40 WAGEN!

A PAK 40 WAGEN. THAT would be a sight for battling.

There's a guy at rctw who is also doing half tracks, he's quite a talented designer, and he plans to do the D, with the PAK 40. Handy for him he has already designed the PAK 40 and sells that right now. His name is Will, and the best thing about his half-tracks is that he plans to bring them in for under $400, and that will include Motors and tracks.

More test printings took place; this time the hull and engine hood. They‘re only brief cleaned with small parts of remaining strutting visible.

The hull was printed with a Peopoly Phenom.

I've made a check of wear of the resin sprocket because I'd some concerns regarding durability of resin:

https://www.youtube.com/watch?v=epwf...ature=youtu.be

The load was 0.7kg; the endurance test was 1 hour at high speed with 50 times on/off.

I'm amazed about the result!
Nearly no visible wear at the sprocket, rather more finish of the metal tracks sticks at the sprocket.

Wow, nice test results!!! Will you print the wheels and sprocket in black so all you have to do is paint rims the base color and leave the rubber black?

@Maus45, I'll have to check if that's possible.

After hours and hours of printing all necessary parts for the prototype are produced; it’s a lot







There will be an upgrade for spring loaded bogies and wear resistant drive sprockets:

Let‘s start the brief build report.

Pictures of the hull and the motor deck…





…after little reworking it fits



Mounting the back panel…





Next is the track gear…





…the idler mount…



…and the bogies.





Movement of the bogies should be good enough.



Mounting the tracks for checking again…

(almost looking like an alligator )

Think it looks better without the front wheels... Would probably handle better without them too. Looks great.

Some progress to report .

first are two videos; one with metal tracks...

...and the other with printed plastic tracks

After applying a dark grey primer this is the current status





















To compare the size or scale respectively, there is a tank commander from Classy Hobby 16004 next by.

That's amazing.. After I finish a couple other AFVs I plan on doing one of these too, but in 1/12 scale. You know, if you print out each of the spring leaves in the front separately, you can have a real working front suspension too

It looks good, but I'm not seeing a lot of movement on the road wheels. What kind of suspension do you have in there? Are they just fixed axles, or does it have an actual working suspension?

So it does not have an active suspension, it just lets the bogeys pivot in pairs. Hmmm, not exactly what I was looking for. I'll hold out for the wcp model because I know that's going to have an active torsion bar suspension, just like our model tanks do.
