I'm trying to get an idea on what aged parts go for. See below and let me know. View attachment 135225
If you're thinking of making and selling them as a "thing you do", then I'd say you could add one hour's labor to the cost of the bridge. Your labor in this case might be worth $10 or so.
I've been having a devil of a time ageing my tuners. For some reason I can't get the same result, as the other prts I've done.
I placed this in a sealed bucket with a top. Inside the bucket was a cup of myriadic acid. The fumes attacked the metal, and I left the bridge in there for 12 hours. Will I sell it? Not sure. I really have no use for it. I also did a bang up job on a neck plate and string tree. http://www.talkbass.com/forum/showthread.php?t=567750 I guess I could sell it. Not sure if I'd sell them separately or together. I will think about it. Not even sure what a new MIM bridge goes for. Make me an offer.
If you ever decide to offer the service, let me know. I'd like to relic the chrome parts on my p-bass. Not a lot, just enough to take the newness off the parts.
Thanks for the offer, but I'm barely understanding the process. God forbid I screw up someone elses parts.
