G'Day all
Norman, Surplus Shed here http://www.surplusshed.com/pages/item/b1077.html
have some Canadian Balsam, sold in relatively small quantities.
Super Glue doesn't stick to glass. It appears as if it will but it falls apart after a few days. It also won't give you any time to set the lens correctly before it sets.
The modern glue is a UV cured epoxy with the correct optical refraction. Epoxy gives you enough time to optically set the elements before setting.
If its a good lens it might be would be worth sending out to get properly done, if its not then I doubt than any cementing that you can do at home would be worthwhile.
If you hold then lens under a lamp, you can count the number of reflections of the lamp that you can see in the lens. Every glass air surface will give you a reflection. You will have to move the lens around a bit to see.
Good luck with your project.
Cheers
Greg
