I also have used E6000


I also have used E6000 successfully for quite some time.  I rough up both sides using a Dremel type grinder, clean and dry really well, put a fair amount of glue (enough for it to eek up a tiny bit around the edges of the bail), and then place them face down on a cookie sheet.  I put the sheet in the oven at 200° and cook for 2 hours.  They are left in the oven without being disturbed for 24 hours.  I have ocassionally had to take one off, but it gives me a devil of a time.
