I can't see any holes (or remember any) but I will have a proper look tomorrow. Even if they are there they "aint" working because of the linking I'm seeing along the side in some places. I have tried warming the barrel along the rib with a torch but as you say don't want to melt any solder and they still leaked...only 24hrs later...really annoying.
