Thought I would add my recent experience with DIY plating. Shout out to Norm for his post on his process and setup...I used this as the basis for my plating setup. I have gotten very good results with the zinc plate and the yellow chromate - this weekend was my first attempt. I was not able to get the black chromate to work well so still trying to figure that out.
Here are some pictures of my setup, a stud with zinc and parts drying.
I really see the benefit of being able to plate parts on an individual basis as you need them.
