First attempt at Zinc Plating
« on: October 04, 2013, 12:12:28 AM »
Well I finally got around to try out my zinc plating process.  Everything seems to have gone ok for the first prelim run.  I believe once I get more parts and the process down I think these parts will come out great.  Figured I would try it out on a broken clamp.  I only worked on the outer ring portion of the clamp and nothing else.  I also think once I blast these parts they will take better.

After first dip.


After third dip and scrubbing.

Darrel your work looks good. I have found a real fine SS brush works well to even out the finish on some parts great for screws. 0000 steel wool works also. It is nice to plate at home so you can clean & plate as needed. George

And the chromate conversion.




George, thanks for the tips.  I'm really starting to enjoy this.

Not bad - in fact, not bad at all. Did you bead the chromate version ? I bet if you top coated with clear it would be dynamite. Probably last forever, too. Great job -

Thanks!!  I guess it is sorta a bead process.  I havent tried it with these parts yet but in the past when I have cleared chromate parts it tends to wash out the rainbow coloring.  It may have been my process.  Ill try to clear this clamp and see what it looks like after.

Darrel, I would think the clear would really change the finish. I try to polish the Zinc plating as much as possible before the chromate or Yellow cad dip. That should give you a brighter finish.Try to dip it for a shorter time blow dry and check the results. Ten seconds plus or minus really changes the color. Here are a couple pictures of some AC fittings I restored in this link.  http://www.camaros.org/forum/index.php?topic=9859.msg77826#msg77826  George.

Like I said my past experiences turned the chromate finish to just a gold finish after clearing.  That was my first attempt with the conversion process.  I hope to get a few other pieces finished before this weekend.  Ill post them up once I am finished.  Since that piece I showed of the clamp I do not allow the part to soak any longer than 15 secs..  Those AC fittings look great btw.  How many times do you strike your parts in the zinc bath?

This looks really good.  Did you use some kind of kit?  Thanks, Scoop

Just once, but sometimes I have to plate for a longer time frame to get good coverage. George

That looks like a CASWELL plating job to me.
http://www.caswellplating.com/kits/index.html
I purchased a kit in 2000 and built a variable power supply. I found the finish difficult to obtain (I lacked the necessary brighteners) and got a  dull gray finish. A Lot of the problem can be in your prep. AVOID sandblasting of any kind. You need to clean and polish the surface to obtain a smooth fresh plated part.
Your progress looks good.

I gave up and found a Local Plater who plates the equivalent of a 4 x 8 sheet of plywood part's for 130$ per lot near a local airplane manufacture in North Seattle.
