Curti Posted October 23, 2009 Share Posted October 23, 2009 Superior plating in downtown Minneapolis has shut down their cad line forever. In the past I have had many parts plated with clear (silver) cad. Does anyone have experience with Zinc palting? Link to comment Share on other sites More sharing options...
MCHinson Posted October 24, 2009 Share Posted October 24, 2009 In case this helps.... I saw this posted on Ahooga.com by Steve Plucker... I found a place in Broomfield, CO that does the ORIGINAL STYLE Cadmium Plating (Dull Cad.) for those who are interested AND they use the "Cyanide" process. Aro Propeller9616 Metro Airport Ave.Hanger # 44Broomfield, CO 80021303-469-1749800-525-8756 Cost: 16 lb. minimum @ $85.00 and $4.75/lb. over the minimm poundage. $10 Hazard fee. Parts MUST be clean OR they can clean them but that is a $75.00/hr charge if they have to clean them. Link to comment Share on other sites More sharing options...
Ivan Saxton Posted October 24, 2009 Share Posted October 24, 2009 Take a look at www.janekits.com.au People who have used his stuff are enthusiastic. I dont see Cd listed but that is not an idication that he would not supply if required.As I recall it has good adhesion and corrosion protection; and the original electroplater I first used did Cd base on some very average wire wheel lock rings with Ni on top, and the protection and appearance have lasted very well. Needless to say, if you get to do this yourself you will be dealing with something that is very nasty biochemically, and you must follow precautions rigorously, or permanently compromise your health. You may be able to source do-it yourself supplies similarly where you are; but always remember that the advice and method are often more valuable to you than the chemicals.

Shop Rat Posted October 24, 2009 Share Posted October 24, 2009 2009 Official Judging Guidelines.Page17 Item 7. There will be no deduction for the use of aluminum paint or stainless steel to simulate cadmium plating as long as the final finish actually simulates the apprearance of cadmium plating. So if you can't find a shop to do the work this might help you. Link to comment Share on other sites More sharing options...
Guest Jim Morningstar Posted October 24, 2009 Share Posted October 24, 2009 I live in Michigan and use a plater in Madison Heights that does cad plating. They are very reasonable-I had 5 split rims and 100 pieces of Jaxon clamps, acorn nuts, wheel bolts and nuts done for $250.00. I have also had door latches, hood latches, hinges and many small parts done by them (Plating Specialties) as recently as September, with excellent results. The key is to prep(metal finish) the part as best as possible. A rough surface as from shot blasting or aluminum oxide will make the finish frosty looking. Fine sanding and wire wheel final prep make the part as new and shiney. Link to comment Share on other sites More sharing options...
Guest Skyking Posted October 25, 2009 Share Posted October 25, 2009 We use a place here in Providence called International. They did most of the cad plating on my 60 Metropolitan. Link to comment Share on other sites More sharing options...
Curti Posted October 25, 2009 Author Share Posted October 25, 2009 Thanks for all the responses. I fear that in the near future all cad plating will shut down by our friends at the EPA. I still wonder if clear zinc looks like cad. I know that cad is more resistant to the elements than zinc, but the cars I restore are not subjected to the winter time salt. Silver paint just isn't me.

Restorer32 Posted October 25, 2009 Share Posted October 25, 2009 Ask for "zinc with a conversion coating". We have it done on a regular basis. No one has ever questioned that it isn't cad. Polish just a bit with fine steel wool before installation. Link to comment Share on other sites More sharing options...
Curti Posted October 25, 2009 Author Share Posted October 25, 2009 What is a 'conversion coating'? Link to comment Share on other sites More sharing options...
Restorer32 Posted October 26, 2009 Share Posted October 26, 2009 No idea why they call it a "conversion coating". It is basically a clear plating of some type. Link to comment Share on other sites More sharing options...
Guest 60electra225 Posted October 31, 2009 Share Posted October 31, 2009 This should explain it.Chromate conversion coating - Wikipedia, the free encyclopediaConsider yourself lucky you still have it in some places. It was outlawed by the EPA in Australia more than 10 years ago, so Zinc is the only option. Link to comment Share on other sites More sharing options...
tbirdman Posted November 27, 2009 Share Posted November 27, 2009 When you get your fasteners cadmium plated, do you worry about hydrogen embrittlement caused bythe plating process? Link to comment Share on other sites More sharing options...
Curti Posted November 27, 2009 Author Share Posted November 27, 2009 No, I wasn never worried about hydrogen embrittlement when I was using cad. I am using zinc now. It will be OK for the kind of use my cars get. Link to comment Share on other sites More sharing options...
Guest Robin Coleman Posted November 30, 2009 Share Posted November 30, 2009 Cad plating is not meant to be a durable coating. Think of it as a sacrificial anode. The elements attack the cadmium instead of the metal underneath. It is easy to do at home for small parts. Check out Caswell Plating on the web. They sell the kits. I did all the parts on my Norton Commando with one. The results were perfect. Link to comment Share on other sites More sharing options...

I did all the parts on my Norton Commando with one. The results were perfect.I tried the Caswell plating and did not have great luck. Anyway my question remains. If you don't bake the parts that you have had cad plated, don't you run the risk of hydrogen embrittlement? Link to comment Share on other sites More sharing options...
Guest Robin Coleman Posted December 1, 2009 Share Posted December 1, 2009 tbirdman...I had great success with the Caswell system...Just make certain the parts are beyond clean, and do not touch them for an hour or so after rinsing them off. The number one rule in any plating process is clean, clean, clean before you start. Link to comment Share on other sites More sharing options...

Guest Old School Plating Posted June 3, 2015 Share Posted June 3, 2015 Hydrogen embrittlement is formed in all electroplating processes ( zinc or Cad ) but it does not effect ferrous materials under a hardness of 40 rockwell. On steel parts electroplating 40 rockwell or harder the hydrogen can be remove with a bake out at 375 degree F for 3 hours with in 24 hours of the plating process.
