I normally use heavy brass caps (5 inch diameter) on stained glass lamps. I pre-tin the inside of the cap with solder, then line the cap up with the lamp and continue soldering the cap to the lamp. Usually, this works just fine but occasionally the cap begins to peel away from the lamp! The solder simply breaks away from the brass cap.
I would be grateful for any advice!
Many thanks, Andrew
