Nickel plating with nickel acetate, nickel chloride, sulfur, saccharin and coumarin I am a hobbyist trying to learn/apply a nickel electroplating process that I can safely do at my shop.  My substrate is a machinable non-stainless steel with unknown carbon content, and I'm looking to do a close variation of the "Watts Bright nickel" formula.  I have a 99.9% pure nickel anode, nickel acetate, nickel chloride, boric acid, sulfur powder, saccharin and coumadin powders.

The formula calls for nickel sulfate; is it possible to simply add the powdered Sulfur to the solution, or do I have to use a different process to synthesize the nickel sulfate? If so,  can I do so with the materials that I have? 
Also, the Watts formula does not include the saccharin or coumarin, but I know that these chemical additives will increase the odds of a smooth mirror like finish.

Also, is there a recommended quantity range, or at least a starting point, for these two chemicals for this application? Any insights here from an experienced chemist/electroplater would be greatly appreciated.

This will not work. Sulfur ($\ce{S}$) and sulfate ($\ce{SO4^{2-}}$) are two pairs of shoes. The oxidation state is different and there is no way that sulfur powder will turn into sulfate during the electroplating.

It might be possible to heat another nickel salt in sulfuric acid, cool down and wait for the nickel sulfate to precipitate, but I wouldn't do it!

Given that the nickel salts are highly toxic, might cause cancer on inhalation and are harmful for aquatic organisms, I wouldn't mess around with crystallisation and the remaining solution for which you would have to find a safe way for disposal.

It might be much easier to aquire nickel sulfate and set up the bath for electroplating according to the given specifications.
