You'll save money if you use stainless scrubbers for most of the packing and just go with copper mesh top and bottom. Or maybe just on top. Do you have a plate on the bottom of the column to stop the packing pushing/falling through? Stainless scrubbers from bunnings are easy to shape to fit the column, and spread out nicely to fit 4". 3 pack of sabco scrubbers is $6.05. I fit 10 scrubbers nicely into my 330 mm packed section. Andrew's copper packing is top quality.
