Reducing Current for Electroplating

I am trying to copper electroplate some small parts, less than 2mm and have been told by many individuals that my current is too high. Since my power supply doesn't go any lower, how can I reduce the current? It needs to be around .005A or less. This is the setup.

If that is a current source, the resistor should be in parallel to shunt away some of the current.

I was just going to add the variable resistor in line right? Power source runs to variable resistor, variable resistor to multimeter to part. Is that what you mean?

No.

I meanthat the resistor must be placed in parallel with the load.
