I see a lot of comments on using Lead Free bar solder to add tin to the mix. I have looked around at my local hardware stores and only find very expensive and very small rolls of lead free solder for wiping copper pipe joints.
I remember using bar solder years ago to make splices in lead sheathed power cables but have no clue where to find any now.
Where are you all finding your supply of bar solder now days? Any direction on this would be greatly appreciated!
