Looper Posted July 29, 2013 Share Posted July 29, 2013 Ok, this might be daft question but I've a hankering for a copper scratchplate, would it interfere with the electrics? Don't want to go to the hassle of making it only to find out I start picking up radio 4. Thanks all. Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted July 31, 2013 Share Posted July 31, 2013 Shielding is good, saves copper lining. Might be better off using unetched PCB blank though. Quote Link to comment Share on other sites More sharing options...
AngelLaHash Posted July 31, 2013 Share Posted July 31, 2013 The down sides would be copper oxidise and fluffy green And I always got nagged to earth every bit of ,metal but was warned that a faulty amp can send power up the earth line I've not seen that but I'm a noobie to such things happening Quote Link to comment Share on other sites More sharing options...
BigRedX Posted July 31, 2013 Share Posted July 31, 2013 I made a copper scratch plate for a guitar back in the 70s. After spending ages polishing it to a bright shine, it looked fantastic for about a week until the oxidation process started to make it go dull and eventually green in all the places that got a lot of finger contact. I tried sealing it with clear lacquer after re-polishing, but because I couldn't use the dip process (too big and therefore too expensive) I had to use a spray can. Eventually the oxidation started again around the screw holes and then I wore through the lacquer in places with pick use. So if you want it to stay bright and shiny IME you'll end up being disappointed. As for earthing yes it needs to be earthed unless it is no where near any of the electrics or any other item that is earthed. Quote Link to comment Share on other sites More sharing options...
Looper Posted July 31, 2013 Author Share Posted July 31, 2013 Thanks for the input. If I go ahead with it I'll make sure its earthed. Was looking to get an aged look to it, only way to keep it shiny would be regular rubs with brasso, but I don't mind dull with a bit green. Thanks again.

AngelLaHash Posted July 31, 2013 Share Posted July 31, 2013 I used to use a kind of rubber like you find in them pens you can rub out Dark black/gray, but most rubbers should get the green off What we use in circuits when designing them But isn't it like eating the copper, I kniw I got a old circuit and its lime green and no track.

cybertect Posted July 31, 2013 Share Posted July 31, 2013 You could always save yourself the bother of polishing it - go entirely the other way and patina the whole surface completely. Oxidised copper is pretty cool. https://www.google.co.uk/search?q=oxidised+copper http://m.wikihow.com/Oxidize-Copper Quote Link to comment Share on other sites More sharing options...

The guitar is supposed to be earthed. Quote Link to comment Share on other sites More sharing options...
Telebass Posted July 31, 2013 Share Posted July 31, 2013 Use brass. Doesn't oxidise quite as quickly. Quote Link to comment Share on other sites More sharing options...

JPJ Posted August 7, 2013 Share Posted August 7, 2013 A good friend of mine has just started a business doing custom etched and patina'd scratch plates similar to Trussart's and the like.
