Woronko plating tank

[geeteex]

I just got my CopyChrome kit and have been playing around with it. So far the results have been good. I need to plate some 1-1/2" square tubing 33" long in the woronko tank I built just fo that purpose. Can I start with the tube completely submerged in the solution and raise it after each section has been plated? I know the manual says do it the opposite way. How would you calculate the amps needed using a 4"x6" anode on each side? How far down the tube would the nickel plate with this size anode?

Yes, you can run the part from the bottom up.
You must figure only the area in the top wide part of the tank is being plated, so calculate that area for current control.
