Copper Plating
unfy:
kozball: yup, looks like air agitation will be just fine. have a friend that does the reverse (stripping instead of plating). i have spare aquarium air pumps for that :D
----
I'll be adding some vinegar to the solution tonight. Need to work out numbers for how much.

Dan W:
I would be curious to see the surface of a commercially plated bullet under your microscope
unfy:
Went to walmart, bought the under $10 single air channel air pump thing, some tubing, lemon juice, non-iodized salt, and vinegar.
will be posting more in a bit :).
----
Dan: I'll bring a berry's bullet to work tomorrow and take some pics. I'll also bring whatever i plate tonight.
----
edit: was single channel, not dual channel. with holes poked in tubing with hot needle, single channel doesnt seem to push enough air like i want. it's agitating, but not great.
unfy:
brushed, 5min lemon juice + salt pickle, rinse, acetone 5min, rinse, plating for 20min on a C cell.
140.3 grains start -> 140.7 grains finish
start size: .401 -> .4015 to .4025
coating is fairly smooth.

The bullet on the left is the one above, the one on the right was in the tank for 40min on the C cell.
It added 1.4 grains of copper, but came out .4020 to .4030 depending on positioning.
It's also got a slightly rougher finish.
Berry's does between... I think 0.003 of an inch up to 0.008 ? I'm still approximately 0.0015 - 0.0020ish, so i need to nearly double my plating thickness to get to where berry's is.
I'll take these to work tomorrow to see how they look under scope (along with a berry's).
---
I can't scratch either with my fingernail.
unfy:
Left to right: berry 125gr 38, 20min, 40min from last night (both 140gr 10mm)
these were in my pocket for the morning.
although the noses look dark, i believe that's just dirt / etc.... closer inspection seems still shows a copper look.
