Title: Own construction of a mine locomotive
Post by: Design-HSB on December 18, 2012, 05:42:46 AM
Hello,

I've decided to let you participate in my small Christmas construction project.

(http://www.buntbahn.de/fotos/data/8916/13P1050996a.jpg)
Here is the first finished and unfinished parts are more visible.

(http://www.buntbahn.de/fotos/data/8916/13P1060003.JPG)
Even after all 5 parts of this compound lever is one of them.

(http://www.buntbahn.de/fotos/data/8916/13P1040605a.jpg)
This car trailer socket is of course also included.

Now I go back to my workshop and look at times if I do not bring some parts finished.

This car trailer socket is of course also included.


Is this the winner in the unofficial "Smallest Brass Part Ever Shown On The Westlake Publishing Forums"  ?

Would be interesting to know what type of camera /lens you used for this picture, the macro function seems to be quite great.

Merry Christmas,

and here is the first image from the locomotive frame.

(http://www.buntbahn.de/fotos/data/8916/13P1060011a.jpg)
All frame components are joined together to test and fit perfectly.
A first rolling sample, the result, the locomotive will also run.

Title: Re: my small Christmas construction project
Post by: Design-HSB on December 25, 2012, 02:06:05 PM
Please excuse my English text that was so obviously incomprehensible.

It is an assembly with tape purely for test purposes before everything is soldered.
If you know a better method by which I can test the fit of the parts ls it me to know.

In any case, the original locomotive maximum 6 kmh slowly to wet Cars is more than a siege tower in the way and at 20 mm plate wins the locomotive.
After that helps NASSCAR certainly no more tape.

Very fiddly Helmut, nice work. And I don't drop small parts like that ever, they become projectiles from my tweezers before I get a chance to drop them.

Hi Marty,

yes, it is the self-construction of a mine locomotive.
All material shown on my part I have made myself.

(http://www.buntbahn.de/fotos/data/7526/13PA210050.JPG)

BBA Metalist locomotive No. 3, visitor mine Klosterstollen.
Moreover, I have previously controlled by the engine itself visitor moves in the mine.

On the work of, and with very small parts I will still report elsewhere.


Title: Re: Own construction of a mine locomotive (my small Christmas construction project)
Post by: Design-HSB on January 02, 2013, 05:48:39 PM
Luck on,

just my BBA Metalist has completed the first test drive.

The entirety not only on a chassis dynamometer, or a piece of straight track, but with me on the brake mountain monastery of Great model.

After I was able to start up the engine even on the pitch, I am with my own design of drives excellent.


Title: Re: Own construction of a mine locomotive (my small Christmas construction project)
Post by: Design-HSB on January 18, 2013, 07:49:47 AM
Hi all,

after the engine is running very satisfactory indeed I continue devoted to the exterior.

(http://www.buntbahn.de/fotos/data/8916/13P1060063a.jpg)
BBA front with reflector holders.

At the same time I started for the remaining bodies to an etching drafting film.

Hello silent reader and a silent reader,

yes it goes on and I hope it still interested. : wink:
What I would be interested to know whether women also read along. : gruebel:

(http://www.buntbahn.de/fotos/data/8916/13P1060069a.jpg)
The parking brake lever has been fitted.

(http://www.buntbahn.de/fotos/data/8916/13P1060070a.jpg)
It was the same back then re-soldering.

For the first time I had used solder paste and this was indeed wonderfully clean, only the columns were not filled.

Such small details, then see but sometimes only on the magnification of an image.

Meanwhile, I can make for the front mount and all the hardware.

(http://www.buntbahn.de/fotos/data/8916/13P1060079a.jpg)
Front ready fitted.
Thus finally realized where the trailer socket is mounted.

All parts except for the visible nuts and bolts are made ​​of brass and self-production.

Hi Marty and Ray,

for you and all others interested in a report on further progress.

(http://www.buntbahn.de/fotos/data/8916/13P1060084a.jpg)
Locomotive frame with further improvements.

Since I have no suitable rotation possibility that bolts are machined from a plate.

(http://www.buntbahn.de/fotos/data/8916/13P1060080.JPG)
Machined bolt for the buffer plate.

Then also the framework for the new headlights and side walls is formed.

As slow as the locomotive created me personally in mind.

Post by: Design-HSB on February 06, 2013, 06:13:08 AM
Hi Michael,

thanks for the recognition.

But for you and all the others you dare to write something to calm or questions because I too am pleased with feedback as any other participants in a forum.

Hi all,
so now but finally back to progress because in the meantime the 0.3 mm silver Ätzblech has arrived with the other components.

(http://www.buntbahn.de/fotos/data/8916/13P1060090.JPG)
Left frame part soldered Exterior. After I had already made test runs and the locomotive was previously held mainly by duct tape, I have now started the soldering together.

Of course, before that were all the findings of tests and further considerations implemented.
This then also all the outer sides were milled again.

(http://www.buntbahn.de/fotos/data/8916/13P1060092.JPG)
Left frame part soldered Interior for easy alignment and hold during soldering I have the inner frame using the filler additionally screwed to M1 screws from the inside.
Moreover, the whole thing was so in my test drives already had more stability.

(http://www.buntbahn.de/fotos/data/8916/13P1060094.JPG)
Right frame part soldered Exterior.

(http://www.buntbahn.de/fotos/data/8916/13P1060095.JPG)
Right frame part soldered inside view.

(http://www.buntbahn.de/fotos/data/8916/13P1060097.JPG)
Here again is a somewhat freer view of my drives.

So I can edit module for separation and assembly by screwing the floorboards, everything after the desired stability and ease of maintenance.

Hi all,

First of all thank you for your interest and support.

Today I built at the BBA on.

(http://www.buntbahn.de/fotos/data/8916/13P1060101.JPG)
Front and rear of the BBA model.

The lamp guards are mounted at the rear and I have also attached edge protection geschlitzem 1 mm tube.

Everything is back to normal soldered and cleaned once before.

So I have now spent nearly 200 hours to build the engine and still not have finished.

In any case, since you give me here, particularly the possibility Marc models when it comes time for the color I want it to apply to the model.

Helmut I do not understand this statement, if you do not have rotational ability how did you get the bolts round whether you cut them from plate or anything else?

Hi Michael,

I have no suitable lathe, I have milled out the pin with a CNC machine from a brass plaque.

Post by: michael mott on February 08, 2013, 01:45:20 AM
Hi Helmut thanks for the information, seems a bit like making cubes on a lathe with a four jaw chuck, if it is the only tool you have, one adapts.

Hi Michael,

the model, it is always important to find a solution how to do it and this solution is then to use them.

But I had to learn early in my training and again, how to do certain work without any aids.

(http://www.buntbahn.de/fotos/data/6484/13P1060109.JPG)
My education work from 1964 is a cube.

Hello Nelson,

It is all of us are actually not so that we can make models for the sake of it and enjoy every hour.

Now I have to just be lucky pensioners and am now finally able to do everything alone, of which I could only dream of many years.


Title: Re: Own construction of a mine locomotive
Post by: Design-HSB on February 19, 2013, 02:54:47 PM
Hi all,

I have since continued to build.

(http://www.buntbahn.de/fotos/data/8916/13P1060152a.jpg)
BBA model front.

(http://www.buntbahn.de/fotos/data/8916/13P1060154a.jpg)
BBA model back with openable cover for the electrical control.

(http://www.buntbahn.de/fotos/data/8916/13P1060155a.jpg)
BBA model for charging open battery box.

In addition, my BBA has indeed the first use in the 11th International Lahnsteiner model railroad days survived well.

Coming along nicely!
Two questions;
1) why are the (new) upper parts grey and not brass?
2) who is doing the etching for you?

-Marty


Title: Re: Own construction of a mine locomotive
Post by: Design-HSB on February 20, 2013, 10:12:55 AM
Many thanks to Ray, Nelson and Marty,

but I want to answer the questions of Marty.

1) why are the (new) gray upperparts and not brass?
They are etched from nickel silver.
Nickel silver is for thin sheets, because of the higher stability even more suitable, such as brass.

2) who is doing the etching for you?
I leave everything in "Ätztechnik Herbert Caspers GmbH & Co. KG in Solingen" (http://www.aehc.de/ec181227-6ba9-4aac-b304-7fbd1c6c6924.html?1292932608335) etch.

Title: Re: Own construction of a mine locomotive
Post by: Design-HSB on February 24, 2013, 01:44:41 PM
Hi Marc,

definitely my BBA will be painted.

But first I have to build many small parts missing.
I hope that the locomotive will thereby gain even further.

(http://www.buntbahn.de/fotos/data/7526/13P1040226.JPG)
Especially in the control stand of BBA still missing many parts.


Title: Re: Own construction of a mine locomotive
Post by: Design-HSB on August 18, 2013, 09:30:10 AM
Hello,

new here and updates to my BBA.

(http://spannwerk.buntbahn.de/fotos/data/650/medium/image20.jpg)

With the Eplositions protected lamps of the model, it should finally move on.

(http://spannwerk.buntbahn.de/fotos/data/650/medium/image21.jpg)

So the lamp housing to the design of Volker should be.

(http://spannwerk.buntbahn.de/fotos/data/650/image1.jpg)

That came after the plot of the file out of it.
But unfortunately it lacks the finer points of the hex nuts as is nothing more to see.
All this put together Volker neither satisfied nor me.

(http://spannwerk.buntbahn.de/fotos/data/650/medium/image18.jpg)

The lamp housing again for comparison with a coin and the milled additional parts.

(http://spannwerk.buntbahn.de/fotos/data/650/medium/image19.jpg)

This is the first Unsuccessful attempt to manufacture the cable entry.
Unfortunately, only half succeeded, because only 0.1 mm wall thickness that travels easily in milling off and disappears into the exhaust system.

So I'll probably increase the wall thickness to scale and try again.

I'm starting to get the desired result of a full scale grommet detail.

(http://spannwerk.buntbahn.de/fotos/data/650/image22.jpg)

Unfortunately, still not good enough.

(http://spannwerk.buntbahn.de/fotos/data/650/medium/image23.jpg)
Thus, the lamp housings should actually look to plan.
What came out of it, I've already shown.
The lettering Volker had already been removed at the request of the company before.

(http://spannwerk.buntbahn.de/fotos/data/650/image24.jpg)
During my 3 attempt the grommet looks now from already used.
The trappings is milled from me for the rest of the lamp holder ring.

Now the protective rings around the case screws also still missing.

Beautiful work Helmut. What was the issue with the lettering?


Title: Re: Own construction of a mine locomotive
Post by: Design-HSB on August 18, 2013, 02:01:04 PM
Hello Chuck,

supposedly the font is too fine.
Character height 0.3 mm, writing webs 0.04 and 0.1 mm sublime.

But that's not the biggest problem.
The screws for the lid are missing, too.
The cable entry as such is not seen, so I had to have some new milled.


Title: Re: Own construction of a mine locomotive
Post by: Design-HSB on December 11, 2013, 05:31:53 AM
Hi,

it comes with support Volkers on, with my BBA.
Here, a first useful casting of the lamp housing.

(http://spannwerk.buntbahn.de/fotos/data/650/medium/IMG_20131211_115747.JPG)
New cast of the lamp housing.

The diameter of the lamp is incidentally about 9.5 mm, ie a merciless magnification of the model.

Lamp on the rear wall.

I also have the lamp housing forward and blasted.

Hello,

in another forum, I was asked whether the font is still visible, but see for yourself:

(http://spannwerk.buntbahn.de/fotos/data/650/medium/IMG_20131214_175949.JPG)
The diameter of the lid is about 2.8 mm.

Thus, the photographing is the biggest challenge.

I have tiny type on my hard drive - it is used for legal text on jobs where you don't want the customer to know anything!!!! LOL!!!!

Hello,

all loyal readers of my posts thank you, but a special thanks to those who also participate actively contributed with me.

A year ago at Christmas, I have started this project and with the lamp housing by supporting Volker now also able to drive as far as I can continue to be here now.

Thanks again to Volker.

(http://www.buntbahn.de/fotos/data/6263/13Weihnachten2013hsb.jpg)
Merry Christmas, health and happiness for 2014.

Also at the monastery tunnel going any further, because I can solve some challenges there, hopefully.

So I am looking forward to a dialogue with you.

hello,

after I finally had an idea how I could make the seat pan for my BBA, I have also tried the same.

(http://www.buntbahn.de/fotos/data/8916/13IMG_20140929_233448.JPG)
Seat pan made ​​of metal pressed over a model.

(http://www.buntbahn.de/fotos/data/8916/13IMG_20140929_233526.JPG)
Seat breakdown from below.

The sheet should be both stable and can also be particularly good embossing and drag.
Finally, much to me at supper the aluminum lid of a fish sauce in the fingers, which brought the solution.

So now I can finally make to the design of the driver's cab.

Post by: Design-HSB on September 30, 2014, 03:55:14 PM
hello,

Sometimes one comes by accident to the right idea, as in this case with the deep-drawing sheet.

After Volker has specifically asked by the embosser me I want to introduce here.

(http://www.buntbahn.de/fotos/data/8916/13IMG_20140930_230020.jpg)
Embossing tool for the BBA seat.

Consisting of two brass blocks 15 X 15 X 50 mm.
Therein some holes for guiding and positioning except the one trough for the seat shells. In addition to the trough, a wire is soldered, in order to press the circumferential bead in the tray. In counterpart, a groove is milled to.

The raised stamp for the seat pan is created and riveted a piece of brass with the Dremel.

With the support of Volker when drawing the main switch and cruise switch but also goes further continue on the control console.
Meanwhile, the casts of the 3 D models have been delivered to me.

The details are really great too.

Hi Ray,

yes it gives me great pleasure to make everything as accurately as possible after.

Hi Russ,
I do not want to depress you, but to encourage it possible to also try.
That's why I always try to show how I do it.

Hi Marty,
Thanks for the suggestion, only if I so wanted to go into production, I once would have a whole lot of fish canned food.
Whether that would be me then and still taste like it.

In any case, another missing parts and some even very small, it is to build for me a challenge.

Hi Jacq,

great idea but I have no cat.
But my dog likes to eat cats.
But my dog gets a little better as canned fish to eat.

But an even better idea Jacq, do you use for your next project the scale of 1: 22.5 then I eat more fish and can supply you.

Before the fish now also corrupts and even starts to smell, I think I should better build on.

So I got down to the travel direction selector lever.

The lever is made ​​of 0.2 mm spring hard stainless steel sheet.
The first challenge was the 0.3 mm hole.

What came with this 0.3 mm drill.

On the travel switch, I have the travel direction selector lever then soldered easily.

Hello Bill, also an absolutely successful work.
That with the burn out of brass, was then in my Plan B.

Helmut,

Would you consider selling me one or two of your seats?
Just the shaped seat.

Hi Marty,

if it in your model building projects like helping you.

Just please remember the seat is at a scale of 1: 22.5 and has the dimensions of 17.5 x 13.4 mm or 0.688975 x 0.527558 inches.

If so give me an e-mail with your mailing address.

Helmut,

please can you write some 'how to'? Obviously the base plate is cnc milled, but how did you make the crossed cutting in the tubing? Doesn't look like handmade ...

Hello Volker,

I am pleased with your question and möhte they also like to answer.

Parts and tools for the seat frame production.
Since there is no extra-thin-walled tube, I drilled a 2.5mm tube with an extra long 2 mm drill.
So I could make the double tube for the seat frame.
Thus, it holds better and was more stable, have I gotten support angle in the pipe.
These had to cross two slits are cut into the pipe.

In addition I have taken a brass block and centrally drilled a 2.5 mm hole through.
So that the pipe I have not twisted when cutting a 1.6 mm hole drilled in the side of the block to the middle and cut M2 threaded into it.
With an M2 grub screw the tube can now be held during sawing.

(http://www.buntbahn.de/fotos/data/8916/13IMG_20141023_234023.jpg)
Now just need the slots are cut crosswise on the table saw with a thin blade.

Thanks for the extra instructions. Some of these techniques can be useful even for us who model in styrene.

For me, a more realistic sound belongs to a realistic model.
That's why I made and edited sound recordings from the original.
The preliminary result I have loaded decoder in the DCC and even made a video to the sample.

Hello,

It has meanwhile passed a lot of time and so I have once again made my BBA.

Linear servo for driving the brake lever

Yes, I have finally managed after many failed attempts to move the hand brake lever with a linear servo.

But that's not all the locomotive's arm moves with what you can see here (https://youtu.be/PvA-2BKIImY).
