Very clean work Valeriy, I wonder how you keep the soldering so neat?

[wefalck]

Impressive metal-work on the davits. I gather you used some sort of jig to keep everything together, while soldering ?

[Bedford]

You're the brass master!

Keith , when soldering with tin, I use a thin soldering iron tip and after soldering I carefully clean the traces of solder.

No, I did not use the template. A simple soldering process has been applied here.

[Valeriy V]

Rosters , ammunition rail and bridge for the transition are soldered together.

[wefalck]

Very complex soldering project ... and well-done, of course !

Valeriy, beautiful workmanship on the rail assembly. Have you been using heat sinks or different temp solders for the sequencing of the assembly? I understand the small tip in order to transfer heat to a small area if the soldering iron is of a high enough wattage, but will so many small items so close together and the melt point of the solder having a range even a small one I am wondering about the heat transfer to previously assembles parts.

 

Thanks Michael

Thanks, Michael !

In this assembly, I did not use any heat dissipation devices. I applied a simple scheme of sequential actions - initially massive metal parts are welded together and only after that small parts are soldered. In a short time of soldering smaller parts, the remaining larger ones do not have time to heat up very much. Therefore, the parts do not fall apart from overheating.

 

A special role is played by the composition of the solder:  Sn - 50%   Pb - 32%   Cd - 18%

This solder spreads very quickly in the right direction and this nuance allows you to reduce the heating time of the surrounding parts, protecting them from overheating.

 

With this soldering, I mainly use a 30W and 60W soldering iron, very rarely 80W. And only the sharp tip of the soldering iron.

Not sure we can still get solderof this composition - the use of lead and cadmium is being phased out at least in the EU.

[michael mott]

Thank you Valeriy for your explanation, I will see what is available in Canada.

It doesn’t matter, you can buy such solder in Ukraine.  

For instance   http://www.zpsplav.com.ua/pripoi/posk50-18/

Lovely work Valeriy. Like others I marvel at your soldering skills.

[FriedClams]

You have been busy modeling since your last postings in October and what beautiful modeling it is!  Your davits and rail assembly are wonderfully made - an intimidating quantity of fragile pieces to solder up.  Beautiful work Valeriy!

Impressive!

Sweet! (Political remark here) 😉

 

By far the most impressive build ever.

There is no policy, only mutually beneficial trade!

Ventilation pipes .

[RGL]

Dammit you’re good! 

[wefalck]

So, how did you make the cowls ? Galvanoplastic ?

Yes, Eberhard, these parts are made using electroforming.

 

The wax mold is coated with a conductive layer of graphite and lowered into a galvanic bath. I already told the details in my topic above.

[Valeriy V]

Thank you all for your feedback and likes.  

I continue to work on the ventilation pipes. 
I make a mechanism for turning the trumpet.

Elegant way of forming the cog-wheel and the pinion by knurling. I probably would have cut them the hard and traditional way, as watchmakers do.

 

I don't understand, where the drive goes to and what the lever does. Is this a double bevel-gear drive that leads then down inside the ventilator ?

The lever is needed to rotate the gear axis, it is removable.

[KeithAug]

Beautiful work as ever Valeriy. 

[druxey]

Elegant solution, using a knurling tool! Lovely work as usual, Valery.

[Valeriy V]

Pre Installation of parts on the model.

[paulsutcliffe]

Omg that looks awesome, Great work valeriy

 

[Valeriy V]

I greet everyone!  

 I continue to build the model, in the photo the assembly of the aft bridge.
