As I recall that sticky was put there by Mike or Ken and they drilled a hole into the slots center? I do it that way too. I use the small tips that are an inch or two in length on my thin CA bottle and put the tip into the hole and add a bit of pressure on the bottle to get the CA to flow a little and as I draw out the tip I glue the slot too. Done correctly the CA hinge is as good as any as long as the slot is a little snug. If your hinge isn't exactly straight it doesn't create a problem.
