Scope repair

[CWS515]

Is there anyone out there who has tried to repair delaminated lens in a scope? I have an old style weaver k4 and the front and rear lens have delaminated to the point of no longer being able to see through them. I've pulled the scope apart (actually very simpe construction but solid) and pulled the delaminated lens out. What material did they use to glue them together? This is the most indepth repair I've every undertaken with a scope.
Thanks.

Never tried it, but you would have to remove all the old adhesive which would probably damage the coating. I think your best bet would be to look for new lens or send out for repair if it is a classic scope.

Near as I can tell there are no coatings, so I don't think that will be a problem. Even though it something of a vintage type scope, I don't have hardly anything in it and mostly it's the challenge of fixing something I've never fixed before. I've fixed a lot of stuff over the years that probably wasn't worth fixing but it was simply in the challenge of doing it. I know that scope repair outfits can fix delaminated lens so if I can figure it out its "yes I've done that" type of deal. But if all else fails I may have to take your advice and send it in for repair or just simply use the rest of the scope for parts.

Depending on the age, the lenses might have been bonded with the old traditional Canada Balsam or some newer synthetic.

There is a discussion of regluing lenses at:

I bet you could Google some more information.

Appreciate the link. That article was what I was looking for. I had done a search but must not have used the right key words. Thanks......

+1 on ironsightinc. I've had them redo some old steel tube Weavers; K2.5, K4 and a K6. Great work, good price and good turn around. Less than 6 months, that's good!!!
