Thank you for your feedback, colleagues! I continue to produce small parts on hull. Scupper lip.

Yes, Michael, the pressure was constant, but very weak and short. Some lubricating oil was used as a lubricant. The tube did not anneal, brass was already quite soft.

Thank you,druxey ! It's time for the portholes. The portholes on the Varyag had a visor in the upper part. This visor was cast entirely with the porthole.

Paper cannons! This is perhaps more abruptly than all the other amazing things on this model !!! Doris, I bow to your skill.

Keith, your propeller turned out to be very good, but in order to have absolutely everything correctly, it is necessary to twist each blade a little around its axis. I hope that I do not interfere too much with your process.

Keith , I understand that I was late, but maybe in the future these drawings will be useful to you.

Alexander, you work very carefully. I know how difficult it is to turn small parts out of ferrous metal, you do it perfectly.
-
Javier, that's wonderful! This is a masterpiece on the palm of your hand!!!

G.L. , I got all my knowledge of electroforming from the Internet, videos and articles. I added to this my thoughts, ideas and got the technology I needed. You can go the same way.

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.
