Nickel plating removal

Print Post  
I recent bought a Borchardt that has a nickel plated action.  I believe it’s what would be called a military action.  It is not original, has newer wood and barrel with a modern chambering.

My plan is to completely rebuild it into something more appealing to me, with new wood and barrel.  This being a future project I am starting the research now, and I will also be reshaping the action so, I will need to anneal it and remove the plating.

My question being, how do I remove the plating, or who can do this for me?  I’ve never dealt with plating before.

Bob,
Royal plating in Tucson AZ has done several projects for me in the past. Excellent service and fast turnaround.

Bob,

I’ve  done it just once a  very long time ago.  It was a pretty simple process similar to plating but with the current reversed.  I recall that I overdid it a bit leaving the underlying  metal slightly pitted.  Lower current or a weaker solution might have prevented the slight damage.

The preferred method if you want a smooth controlled surface profile, except cast metals, is to use reverse Electroplating or Electropolishing where the part is made into the positively charged anode the opposite of plating creating the electrically charged chemical cell bath that carries off the nickel. Lots of small shops do this work depending on your locale. Electropolishing is used a lot to clean up welded stainless parts. 

Understand lots of early military plating with nickel used a copper bath substrate so I'd doubt if the advertised or Utube claims using sulphuric or HCL will do the job. The pros used high 30-40% concentrations of Nitric and very controlled temps. Nitric will dissolve nickel but as important is it takes off copper too.

I should clarify my original post on this being a military action.  I have done no research on what I have, I should have said a military “like” action.  I say this because it is just a plain action without any of the sculpting like I see on nicer Borchardt guns.  The action lettering appears to be thin and partially struck out from polishing in the past.  So I am assuming the plating is not original and may have been done when the work was done as it is configured today.

Tony, I had thought about them but was hoping someone like singleshotsam who has experience with someone that had removed plating.  I had heard about pitting if not properly done.  I will call them, but wanted other options to also talk to.  I really don’t want to do it, just as soon have someone else with experience remove it.

The Caswell process looks do able. Cost of materials is not in expensive when you add it up and time. Here is a video if you are interested. (You need to Login or Register to view media files and links)

I used the Caswell to strip a nickle Shiloh sharps prior to bluing and c/case, it worked very well.

This Caswell process looks promising.  Thanks for the link. 

I watched the video Lynn, and it did bring up a few question.  The guy removed a chrome plating before using the Caswell product to remove the nickel.

Since I’m totally ignorant on chrome/nickel plating.  Am I correct in assuming this action is just nickel and not chrome plated?  And is also plated though out the interior of the action?

Do you think parts were modified to allow for the added layer of nickel and to allow for clearances back when this gun was reworked?  Thus being looser when the plating is removed.  I know modern plating on firearms is very thin and does not require any special fitting but, what about 50-60 years ago?

Thank you Bob for the pictures. That is a good looking action not pitted or beat up, a bit too shiny for me but still very shootable, what is the trigger pull like? If you have any questions about a Borchardt send me a pm

Haven’t even pulled trigger.  Been looking for an action for awhile so when this one was offered to me I grabbed it.  I’m interested in installing a Zischang double set in it, so the pull it has now didn’t matter to me.

For sure…the shiny has to go.  Never been a fan of plated actions.

I will take you up on your offer when I get to it. Be awhile though.  Thanks
Bob
