Hi All...quick question about protecting chrome from the heat/flame of brazing. I have a frame with chrome lugs. I'd like to have some cable guides and pump pegs brazed on the top tube. They would be about 2-3 inches from the lug and I am wondering whether there is danger of damaging the chrome with the heat/flame of the brazing torch and how one might want to go about preventing that. Not that I would be doing the brazing myself and I will certainly discuss this with my frame builder before getting the work done but I'd like to get some opinions first so that I can have an informed discussion with him. Thanks for your opinions.
