An -11 owner would be able to say for certain, but the
old model
airplane solvent glue was methyl chloride. It's also in a lot paint
stripper as well. "Tenax" model glue is a name that comes to mind.
In the UK, dichloromethane (same stuff) is sold under the brand name
'Plastic Weld', It is _by far_ the best way of mending plastics that it will
disolve. And I think DEC front panel toggles fit into that category.
That said, trying to glue the pivot pins back on to the toggle is going
to be (IMHO) a waste of time. The area is just so small. Personally, I would
drill through the toggle (make sure it's in the exact right direction) and put
a metal pin through.
