Landships II

Thanks Arie and Andy

The "disappearing frame" isn't a problem at all. It disappears only, when I am going to collect all files in one STL file. For printing all parts are separate files. So the frame is still on my harddisk!

@ Andy

Thank you for your words! Your first photo shows a Benz Zugmaschine, often misinterpreted as a Büssing. The second is a Podeus Tractor. You can see both further up in this thread.

Cheers, Peter

 Nice Photo's, I have never seen the configuration on the first photo, Thanks for charing...

All the best

Hi gents!

Once again, whenever I am going to export all files into a STL file, some parts are missing. Here for example the cab, the frame and some minor parts have disappeared . I think this is due to insufficient computer performance. But exactly for that, most details are visible in the pics.

Thanks, Andreas

Although I am very flattered by your words, it isn't art in the proper sence. I am not formally trained and if you are passionate enough you can learn almost everything. It takes some dedication and the proper equipment (the latter is rather missing). But if I can do it, you can as well.

Here some results! Alas, success and failure are never far apart. First, the winch in Smoothest Fine Detail Plastic from Shapeways. Absolutely great in detail (and also in price!!!)

The frame is a different story. It is a cheaper solution from India: The SLA printed High-Detail Resin is simply useless.

So, you see, I am still in the trial and error mode...

I look forward to seeing the finished product!

Hi Arie! May be you don't know: It took me more then ten years to finish my A7V I built long time ago! So you have to wait quite some time too....

But you are the one who knows that difficult subject most! So your words mean a lot to me - thanks!

After a first overwork and priming, the front wheel doesn't look that bad at all. What I find particularly disturbing is the fact, that the rim isn't a circle at all, more easily a polygon. Here I have to sand once again!

Hoi Peter,

Don't'worry, I still have a German WW1 horse drawn ammo wagon (a conversion from the Hät WW2 German field wagon) for a 21cm Mörser that is still waiting to be finshed since 2014, so I know the problem. 

Indeed, I think that of all the people following this tread that I am best aware of all the problems you have faced. I think that you got stuck on the same details that I did. Nevertheless, your work still looks great and to be honest way better than mine!!

I see your problem with the wheel. My software sets a cirlce to 24 parts. This should be more or less okay for the scale in which I work (1/72), but in your scale this will look like 24 faces that form a circle. What I do for wheels, is set the circle to 96 parts. I also have had a try at the Fahrpanzer, for which I set the cirle for the main body to 360 parts. This way it will look round, even in your scale, even though it never really is. But sanding also works... 

With kind regards,

-Arie.

Hi Peter,

I always used to redraw the offending part as it never occured to me if it could be corrected until you asked me this question. After some trying I found out that even with my ancient version of Sketchup the answer is yes, it can be corrected. Select the relevant circle, right mouse click, select Entity info and where it says segments, change it from 24 to for instance 96. Enter and you are ready, so I doubt that this is not possible with the software you are using. So I learn something new every day.  I hope this works for you.

With kind regards,

-Arie.

Oh, and the four pieces of pasta in front of the wagon are in fact 21cm ammo baskets... 

Today cab and bridge arrived from China (Hmm, although I ordered them in England) and the quality is surprisingly good!  Now the replacement frame is the only major part that is missing.

After nearly cutting off part of my finger trying to carve the planks on the inside, I set it aside and I haven't done any work on it since then...

Hi Arie

Nice little (... from my point of view, everything smaller then 1/25 apperars little) ammo wagon and very detailed too!

Your "nearly cut-off finger " makes me think of another problem in 3d (and general) modelling: Reproducing wood grain.

So far, I used basswood (lacquered and sanded before painting) with good results. Here an example from my last diorama.

With the use of 3d technology this has turned out to be more complex. To be honest, I haven't found out how to recreate the woodgrain in my CAD drawings, so I just omitted them in the actual project.

Obviously there seems to be a solution. May be this link is of interest ...

P.S.

Setting a circle to 96 parts won't work yet. But I have to take more time and try it once again!

Hi Peter,

Thanks for sharing the article on making woodgrain in 3D. I have had a stab at Blender, but I haven't got the hang of it so far. But perhaps this will be a good reason to give it another try, so Thanks!

With kind regards,

-Arie.

Hi Peter,

Your excellent work has inspired me to continue with my vehicle as well. I just finished the back axle with drive system and tow bar.

With kind regards,

-Arie.

Hi Peter, 

I am sorry to hear of your problems with the prints. SLA can indeed be very brittle and parts, especially thin ones, tend to break or even shatter. You could ask for a tougher resin to be used. I believe there is some ABS like resin, but I have no experience with it. 

As you already told me that you take 10 years with your projects, it will probably be me that will finish first...  Then again, while making a backup of all my files, I noticed that the first file was from january 2020, so I have been working on this for nearly 3 years now.

Love the water taps! Are these on the vehicle as well? Probably in the radiator?

With kind regards,

-Arie.

Hi Peter,

Thanks for the clarification!

With kind regards,

-Arie.

I am in contact now with a manufacturer who showed slight interests in producing a small batch of my Büssing in 1/35 scale. That’s why I have to redesign much more parts, as with the SLA- technique much smaller details (which I had to simplify just to make them printable) can be printed.
Although, there are still a lot of « would » and «could» in the whole thing, I am working almost obsessed and so I am progressing slowly but constantly!

Here some examples of some redesigned parts:

[Rearwheel devided in three parts needs less supports]

[Engine with more detail parts]

Cheers, Peter

Hi Arie

It is almost a neck-and-neck race between our two Büssing’s. ;-D

Seriously, I like very much, what you are doing in that small scale. However, I really do wonder if all that tiny details are printable. I am struggling with that problem even in 1/35 scale…

The cabin too had to be improved, and IMHO the new one looks really better in terms of shape. All this could only be archieved in improving my CAD-skills too with the help of countless tutorials... Huh!!!

old

new

Cheers, Peter

If this would be a race, you would have won - you are already printing your parts!!! 

However, mine is also in the pipeline, and I have to get through this challenging stage now. That's why I am working restlessly on (my first commercial) project, which will be produced from this French company hopefully during this year:

Cheers,
Peter

...besides, I have started this project over 3 years ago, so you work a lot faster than me... 

...and without your help I would never have been able to finish these drawings, so thanks!

Hi Arie

As I remarked already: a very fine Büssing you are doing here. Thus, I will get a good impression how my Büssing should look like!

This morning however I discovered something I hadn’t considered before. It is that box-like construction at the load plattform front. Could it be, that I had overlooked something???

Up to now I made out, that the two side doors would have served to unload munition from the railway wagons onto the lorry (Ok, with a lot of imagination from myself). Here a rough sketch to scale – the distances would match.
