TECHNOLOGY OF APPLYING METAL TO PLASTIC, GLASS-TEXTOLITE, GLASS ....
A thin layer of glue is applied to the prepared degreased surface (for epoxy resin), it is rubbed with a swab, then we sprinkle the surface with a bronze powder (the paint is sold in household goods) and then go through the whole surface with a dry swab to allow the bronze to adhere well and leave it to dry.
Next, we prepare a solution of a pair of chlorine tin. We take hydrochloric acid, we throw into it pieces of pure tin also put on a water steam room (tin is etched in hydrochloric acid at a temperature somewhere from 90 degrees). We warmed the water bath around 6:00 , then we take the system to which the bronze paint has stuck, we make a diversion, we can press the exposed copper wire around the outskirts, if the system is an impressive type of plate - there are a few bows. You can drill the holes to insert the bolts.
Then pour or apply a brush solution of a couple of chlorine tin. Bronze brightens, the surface becomes conductive (tin stump). We lower the whole structure in some capacity (minus will be our product, plus some copper gizmo), fill the electrolyte with a voltage from the calculation of 0.1A to 1kv dm, if the current is strong the surface will turn loose (with normal electrolysis, copper settles smoothly, well is soldered). Can be coated with silver. If there are any gaps, you can correct it with a simple pencil.
I certainly do not forget about the solution, but it can be found in any edition for electrotype, I remember that there was copper sulfate, a bit of sulfuric acid, and alcohol, you can drink ammonia or moonshine.
At what time he was engaged in electroforming, tried to precipitate copper on quartz. The current should be somewhere 0.2-0.5 mA , quartz at 9MHz drove to 8MHz , if you switch the polarity upwards - went somewhere up to 9.3MHz more ... In general, it is necessary to accurately place the plate joints with rosin solution in alcohol. And yet, if you poison remunerations in copper sulfate, you can update it also improve. Try to lower in the pickling solution a pair of graphite rod from the batteries, connect to the battery through a light bulb from the flashlight for the night. In short, while the solution will lighten up, blue crystals will also be deposited in place of copper, this solution will work faster, I have a 3-liter bank dissolved in 1985, and it still persists till now.
