HP-67 keys wanted

[Brad Barton]

I don't have any keys but i wonder if a carefully controlled toaster oven could be set at just the right temperature to "reflow" the surface of these keys. You'd have to be very careful not to over do it.

I once saw an Instructable on how to do it. Here it is. It's not something you want to walk away from, but it looks like it would get you very good temperature control

You could take a single key and, starting at a low temperature, leave it in there for varying times and see if they can be saved. Someone with injection molding experience may be able to tell us if it's worth trying.
