Does anyone know of a good epoxy or even a double sided tape that will bond
Teflon or Delrin to Nylon or other plastic?

Absolutely impossible with Teflon. The only way is a nasty chemical
conversion treatment of the Teflon surface into something bondable. You
can order material so treated on one side from mscdirect.com. Search for
"bondable ptfe". Ordinary epoxy will then work quite well.

There are some adhesives promoted as having several hundred psi of bond
strength for Delrin, but lack of peel strength is a problem. In any case
it's a tiny fraction of the strength you'd expect from epoxy on easier
materials. But it is more than zero.

There are many adhesives that work with the "other plastic" you mention, but
none that I'm aware of for Delrin and the like. You may want to try heat
welding them.
