Can be a Coelian as he would have in 1946

Hello,

After some time I would like to once again build a tank for me , except that I need a course with the latest technology for presentations . Until Munster he should then at least able to ride .

Since I have a penchant for paper armor , Asiatam the Coelian tower now has on offer , I have built the latest gear for the Panthers , the idea was not difficult.

For tank itself

The Coelian was indeed built hull with a Atrappenturm on a panther. So is one to think that certain freedoms as such a vehicle could look like in 1946 ....

So I 'll put the Coelian on a Panther G hull with steel drive. My reasoning for this is this , that for such vehicles often damaged and repaired vehicles were used and the G version would have been replaced at this time increasingly of the Panther F . I 'm on to consider whether I will provide the tower with a different paint than the tub , but that I decide then during construction.

First off, I build the lower hull and this I have already standing in the shell with me.

Here's compiled the most part .



Most of all components used in the construction are so castors with me accrued remains the Asiatam King Tiger that there is not more to buy in this form. I have not found enough of it to build a steel drive as it was described by Atzemann some time ago in a post.

For the steel drive I disconnect the 8 caster wheels and connect it again with a brass spacer.





So I splicing all wheels together. These must now be only times 24 hours.



After the rollers cure now I 've started with the transmission and the cheeks and fitted as a block in the lower hull .

  ciao edwin , interessante da seguire anche il nw progetto del Coelian su base Panther G , scafo in metallo con gli splendidi riduttori da te elaborati .... buon lavoro robby62 e riky94 ....   

And on it goes , but for other things . Since the Coelian will be heavier than usual , I think so to 10.5 kg I have to adjust the stiffness of the hull that weight too.

That's why today I first wound springs and not only for the Coelian , but also the same for a few other tanks.

The lower hull I had built for a travel weight of 8.5 to 9.5 kg in weight and to take account of this extra weight I'm building now 4 stronger springs in four swing arms a . Here you can see a little difference of the springs. Located in the center is a stronger one.

In order to gain a general impression of the Coelian I compiled it once loose . That will be a nice chunk, so the size of a KV 2

In addition I have the steel rollers in the later arrangement made ​​, since the question arose how they are installed . When steel drive I'll stay by my previous research well .
This is an equally rare drive that was still used in only a few Panther and it is no longer available in this form for the King Tiger .

My Coelian grows and thrives nice and slow .

I have made further first on the inner gear block .

The walls are fitted into the hull , and processes the gears beginning to install .





In the lower hull I wanted this time to make an exact match electronics . So I had to disconnect an 8 cell battery and connect the two halves with cables.



So now I could draw an exact match use and printing.





And even in drive it went a little further .
The drive axles , I had already done and had to just turn something suitable . Then I also have two late idlers found ...



To be able to do with the drive wheels on but I must first mount the rollers and then align control and drive wheels afterwards.
So I first made ​​the axes for the eight wider wheels.
These are made of silver steel and as a stop do I solder a small washer on hard .
For this I stretch it standing in the vice , put some flux under the centrally placed washer and put a very small portion of silver solder in the middle.



Then I warm the axis has been so long from the bottom to the braze .





After cleaning the axles , I can now mount the first eight casters.

By the way still runs the 3D printer for the Coelian . Now that I have also printed a speaker was for the interior nor a control box behind the motors turn.



And so it looks tidy, but later in the tank properly.



But really went there today with the drive on. To mount the center rollers at the correct distance I needed first 8 6.5 mm long brass tube as spacers .



So then I could install the missing wheels.



In the late idlers first some tweaking was necessary. This I had to turn to each 1mm on the inside and then they could also be attached appropriately.





The assembly of the drive wheels and countershaft turns out a little more difficult . First, I have the tracks properly aligned with the aid of an aluminum bar and set the exact position of the track and drive gear.



The drive shows up as even of a new page.

Now that I know exactly where I can solder the drive gear on the axle hard I have this first elaborate a bit .





The axis also slightly roughened and put together in the correct location on a fireproof surface .





So I could then hard soldering and cleaning.





Just as I did with the small drive sprocket.





And so now the forces to be transmitted .





Now I only had to assemble the lid of the outer gear. This is completely filled with grease and screwed to the tray and adhered .







Through the triple ball bearings per axis and strong axis , the torque is now transferred to clean the tracks , but first , the adhesive must still dry.

  il tuo coelian prende sempre piu' una struttura interessante , bel lavoro pure sugli ingranaggi di rinvio motori , e come sempre nei tuoi lavori metallo a tutto campo , salutoni robby62  

And it goes on , so at least he can drive well in Munster .

Today, I have made ​​ready the first attachment of the transom . For this purpose, first to double up the sides as on the front with plastic sheets , crop and files.











Then I have with " STABILITH express" closed all open columns of the transom to the pan . This adhesive is for ideal because it has approximately the same hardness and properties of the plastic of the upper hull .



I have also done this with the terminals of the upper hull to the lower hull . Prevents the tape in between, that the parts stick together finally and still no gap. So the connection is later virtually dustproof. The adhesive cures relatively quickly and can be in the gelling Zusatnd first almost filling and later simply cut with the utility knife . If he's hard as you can hone and polish the plastic tub it as well.







Thus, the upper tray fits now sucking on the lower part and only holds two small magnets simply held the bomb .

I nich screwed the turret ring to the tower base to end for today.



That fits just like in all HL- models and also the height right through a small paragraph at the Resinteil .



However, I must nevertheless there can still come up with something , because the tower so easy to difficult turns , but at least things look already slowly like a tank from .

In order to continue with the tower drive , I first set the speaker and other internals back into the tub.



Thus, the tower can be rotated acceptable to Build 4 small but wide ball bearing into the hull top . In order to achieve a distance of 0.5 mm between the tower and the roof I had the axes of the bearings unscrew something .







So I could then glue from the bottom and support the axles with plastic pieces.





So I Konnet the ring gear from the bottom tightening and it fits quite well.





Since the normal tower drive is too slow , I use a mini servo , to which I have set the drive gear of a HL gear.



To the still good and properly attach I drew me a small bracket that I 'm going to print it tomorrow .

A very small little went here on today.

I have printed the first servo holder and so glued the servo it.



The servo I have cracked and so I need a controller to operate it. For this I use a micro controller of the power from the receiver gets and so I do not need a separate feed lines.



And so I then glued in place.



The drive works quite well now and gets on well with the weight of the tower, but unfortunately it is too slow for me. A revolution in about 8 seconds is just too slow for a flack tanks. Since I'll probably still install a faster servo. The tower was later able to make one revolution in about 3-4 seconds.

The tower servo I have exchanged today. Was just a small effort and now the tower is much faster now. While he has still not the optimal speed, but I'll now first way.

By the way I have a few Etched found for Panther and dabbled in the anterior chain plates.







I did this intentionally bent and dented. I do not have a picture of a tank in use seen in which these sheets would not have been bent and so I will build my Coelian.
