Bedford, agree with you, in Russian there is a saying - "Devil is not so black as he is painted". If you wish, soldering can be easily mastered. As a flux, I use zinc etched soldering acid. Judging by the photo, your approach to soldering is at a high level. -
Thank you, Michael! You are a Master of your craft, and I appreciate your attention to my work. I am very pleased to follow your work. The large scale of the model confronts you with special difficulties, and you successfully overcome them. I have something to learn from you! Each item spent approximately 8-10 hours in the electroplating bath. The slower the process, the better the detail is obtained.

The power source operates in DC mode, so I only regulate the amperage. I set the voltage to maximum and only once, I do not regulate it later.I follow the instructions for the power source, here it is: DC POWER SUPPLY HY1500-HY1800 DC MODE 1. Turn the voltage regulator clockwise until it stops, and current control counterclockwise until it stops. 2. Power on the instrument. 3 Connect the positive and negative outputs of the device to load. 3 Turn the current dial clockwise to set the official value of the output current.

Lou I tried to answer your question in a previous post. You need to understand that these formulas are needed to start the real process, in the course of work, you will definitely adjust these indicators as your experience becomes available.

I will try to answer questions as far as the translator and a small stock of my knowledge will allow me. 1) Recipe for cooking 1 l. electrolyte for electroforming: - we part 200 g of copper vitriol in 500 ml of water - we filter the resulting solution - add 134 ml. automotive electrolyte density of 1.28 - bring distilled water to 1 l. and mix well 2) Deposition Current: 15 mA * S (part coverage area) 3) To calculate the time of deposition of copper on small areas: t = (840 * m) / I time - in hours, mass - in grams, current - in milliamperes 4) Copper precipitated mass: m = (S * h) * ρ m - mass of copper in grams S - area in cm2 h - thickness in cm ρ = 8.93 g / cm3 - the proportion of copper 5) Any pure copper is used as an anode.

Joachim , I will show the process in pictures, if you have any questions, I will try to answer them. It will be good if the pictures do not mix up after my upload to the forum......

Since we are talking about shipping company models of the 1900s ... For the time being, I have been looking without success for detailed photos of two models of liners of the type "Empress of Japan" (1895). The first model is stored in Vancouver maritime museum, the second model is in the Canada Science and Technology Museum Ottawa. Perhaps one of our members of the forum will be able to photograph them in detail?

Thank you, Chris. This deflector is welded from two halves. Each half is made of copper by electroforming. At Varyag deflectors will be made by the same method of electroforming, but with whole details, without halves.
-
Colleagues, thank you all for your kind words. I hope you will also like my reports on the construction of the Varyag.

At the Varyag still ahead. The reasons for stopping work are temporary and undoubtedly the model will be completed.

Hello Joachim! I find it difficult to understand your question, since the translator does not translate the technical text very well. Please indicate with the arrow on the photo what detail you are asking.
-
Thank you all for your emotional evaluation. I am glad that I liked the model, although it is still far from complete. I often repeat the same words looking at models of sailing vessels made of wood and even paper on this forum.

Work on this project is temporarily stopped. Ironclad "Peresvet" , scale 1:50. Under the sheet of his hull , length of 2.65 m.

Thanks to all who follow the construction of Varyag! Thank you for your attention to my work! Congratulations to all the masters of this wonderful forum Happy New Year !!! I wish you all a good mood and good luck in building your wonderful models !!!
