Unglued Miyata Frame

[Cazza]

I have a mid-eighties Alumi-tech Miyata road bike with "Miyata exclusive aluminum tubing" using their APA bonding. The top tube appears to have come unglued(?) from the seat tube - the top tube has risen up and is exposing a minimal amount of unpainted seat tube. Can this be repaired easily and cheaply? I really like this bike - is it worth the repair and will it last?

If the cost of it does not exceed what you want to put into it then go for it. If not look around for another like it then you will have parts.
