Is there a scanner that can work out cubic centimetres?
Oddjob:
The owner of Gateros told me in a conversation that a 6mm x 50mm bolt would be 1/3 of an amp for 20 mins, plating companies only plate for 15 min he said so the extra 5 mins gives you a better coating whilst only being a few more microns thick. If the part isn't a critical fit part you can leave it for a good while and really pile the plating on but not if you have threads etc.
Getting ready for my first attempt this weekend I reckon. Some of the parts I'm going to plate are unusual, we'll see how they come out.

Hi, Ken.
Screws arrived thanks.

I have always worked on 100mA /square inch of surface area for BZP. I got that figure from a 1943 Canning book.
One of these days I am going to make a DIY mini barrel plater as loads of tiny bits are a PITA using the wire 'hanging' method.
You basically have a little plastic barrel with lots of holes in it rotating slowly at an angle in the electrolyte and metal cathode 'danglers' strategically placed to contact the steel parts as they rotate.
I have discussed this with PM 's with Ken but I made a big mistake and tried out 'YouPlate's' ready mixed chemicals as opposed to the 'Gateros' stuff I have used for ten years. I got a really dull finish with the Youplate stuff and no amount of playing around with settings/brighteners will achieve a bright finish ... so voted with my feet and gone back to the Gateros stuff. Well we all make mistakes :-[ :-[

Just to throw another spanner in the works with the water displacement method. When measuring the surface area of the water you will
get vastly different results just by adding a drop of soap to break the surface tension of the water yet still have the same volume of
water.
