I have some 4, 3 and 2 inch stainless ferrules, copper pipe is expanded and I cannot get the solder to take.
I am using aquasafe lead free solder, have tired bakers solder flux fluid and 801 liquid flux. Using Mapp gas torch.
Have even tired this method http://homedistiller.org/forum/viewtopi ... =2&t=46881 but the solder is too large. Surely someone can help me out
