[QUOTE="thor447, post: 4208319, member: 24867"] Grobet USA Plating Guide - No. 62.01215 I went a little overboard in my setup, with a magnetic stirrer hot plate. I also could've made my own nickel acetate, but I decided to buy pre-made solution, along with a good quality activator. The guide is handy and gives a quick reference for several types of plating. Everything is listed in volts, but in my research I found it much better to adjust plating strength in amps, that ways the flow of ions is consistent. The time and amperage needed to plate an individual part varies, along with plating temp, but there are some formulas out there that will guide you as long as you have a rough idea of the surface area being plated. I have a spreadsheet I'm using to estimate watch case surface area, and then some formulas added to calculate plating strength and time. About 10 days of research ended up being worth it in the end. Preparation of the part is key though. It takes 20x the amount of time to prep the part and get it to a level of cleanliness to ensure it passes the 'water-break' test than it does to actually plate the part. [/QUOTE]
