 Labeling/decals for pot controls
--------------------------------------------------------------------------------
 I'm rebuilding an old amp where the chassis face was so pitted/corroded that I sanded and (acrylic auto) lacquered the metal. It turned out very nice. Can someone instruct me on if there is a place to get
decals that are labeled volume, tremolo, reverb, etc ?
I'm thinking of decals with a clear coat over them.

 I found out that there is a decal paper that can be printed by an Inkjet printer to make decals. It certainly could be one way to "reproduce" approximated copies of decals for amps where there is no aftermarket product to purchase. For example, I need decals for a early 60's Danelectro. If I used a digital camera, perhaps I could probably print off a photo as a decal.

Can anyone tell me if they have used that and used a clear acrylic lacquer over it?

 I've had excellent luck with dry transfer letters, you can get them at any high end art supply store, they're available in any font. The only thing is you need a straight edge so your words aren't crooked. Regular rustoleum clear works fine on aluminum.

 I do either engraved brass or reverse engraved plastic laminate.


Reverse engraved.

 Another great idea! I've seen the pictures of your amps and they do look fantastic!
Thanks, tubenit

 I haven't gotten past the felt tip pen on formica yet.
Am looking for someone who can silkscreen chrome.

 how do you stop the brass from tarnishing??
--------------------------------------------------------------------------------
 Hi Casey4
I see that you have an engraved brass faceplate on your amp, I went the same route with my faceplate, but it ends up tarnishing real bad, I have to keep polishing it regularly, is there anything you have done to reduce the tarnish effect?? Thanks in Advance

 I bought brass stock that was "coated" with something, so it won't tarnish or pick-up finger prints.

I would imagine that if you cleaned the brass well, maybe you could coat it with clear Poly spray. Of course you'd have to remove the faceplate.

 Where do you get the reverse engraving done? How much?

Thanks!

 I have mine done locally where they know me. But I am told this place does excellent work.

Faceplates

There might be someone local to you that can do it.

You need to make a 1:1 layoutdrawing for the local engraver, I don't know about the guy at the link.

Any sik screener can screen chrome they just don't like to do it because it doesn't stick as well as they're normally used to. But for our application it sticks fine just don't take a key to it. I do my own and they turn out great. I use Nazdar epoxy ink which is the best ink to use for this appplication especially if you bake it as suggested by Nazdar.
You might notice that with the original fender and repro chrome face plates that the ink isn't very resistant to wear and you can scratch it off if you go at it with your finger nail (which i don't suggest you try with a vintage faceplate!). But again under normal light finger traffic it is fine. So don't take no for an answer from silkscreeners!

 Moose,
where did or do you buy your nazdar and silk screening supplies? I have need from time to time to rescreen chassis where the lettering has worn off but don't know a good supplier.

 I get my silk screen supplies at a local silkscreen supply shop. Any screen supply store should have everything you need including the Nazdar ink. If not check out the www.Nazdar.com site a find a distributor.

Once the silkscreening has been done could you spray the faceplate with a clear coat of something . Lacquer, Poly-something, maybe acrylic ?
